Understanding intraspecific genetic variation is one of the principal requirements for the evaluation of tree species capacity to cope with intensive climatic changes, as well as designing long-term conservation programs. Herein, we evaluated the genetic diversity and genetic structure of seven pedunculate oak (Quercus robur L.) populations, located at the southern margin of its distribution range on the Balkan Peninsula (Serbia). The objective of the study was to propose future in situ conservation measures aimed at protection of pedunculate oak adaptive and neutral genetic diversity at the species rear-edge. Genetic diversity and structure were estimated using twelve highly polymorphic simple sequence repeat (SSR) markers. The mean expected heterozygosity (He) was 0.769, allelic richness (AR) 9.63, and private allelic richness (pAR) 0.79, indicating high genetic diversity in the studied populations. Genetic differentiation among the populations was low (Fst = 0.032). Structure analysis, the unweighted pair group method with arithmetic mean (UPGMA) showed the existence of two gene pools unrelated to the populations’ area of occurrence. Taking into consideration the results of the current study and previous conservation activities on the pedunculate oak in Serbia, as well as the importance of rear-edge populations in the long-term conservation of the species genetic diversity, we suggested establishing three additional gene conservation units for securing long-term sustainability of the species.

Epigenetics has emerged as an important research field for crop improvement under the on-going climatic changes. Heritable epigenetic changes can arise independently of DNA sequence alterations and have been associated with altered gene expression and transmitted phenotypic variation. By modulating plant development and physiological responses to environmental conditions, epigenetic diversity—naturally, genetically, chemically, or environmentally induced—can help optimise crop traits in an era challenged by global climate change. Beyond DNA sequence variation, the epigenetic modifications may contribute to breeding by providing useful markers and allowing the use of epigenome diversity to predict plant performance and increase final crop production. Given the difficulties in transferring the knowledge of the epigenetic mechanisms from model plants to crops, various strategies have emerged. Among those strategies are modelling frameworks dedicated to predicting epigenetically controlled-adaptive traits, the use of epigenetics for in vitro regeneration to accelerate crop breeding, and changes of specific epigenetic marks that modulate gene expression of traits of interest. The key challenge that agriculture faces in the 21st century is to increase crop production by speeding up the breeding of resilient crop species. Therefore, epigenetics provides fundamental molecular information with potential direct applications in crop enhancement, tolerance, and adaptation within the context of climate change.

Urban green areas present a lucid example for the harmonious co-existence of the artificial and natural environments best illustrated by their interdependence and interconnection in urban spaces. Urban green areas are essential for the health and wellbeing of citizens. The present study aimed to investigate those multiple benefits for citizens that arise through the existence of urban green areas, as well as important policy dimensions that should be considered when designing the expansion of urban green spaces in urban development. The study was based on a literature review to examine for available evidence on the benefit levels derived by the existence of urban green areas. An extended literature review was followed by a structured review, based on specific inclusion and exclusion criteria, which partly followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The search was conducted in two databases, and a total of 1674 articles and abstracts were identified through the database searches. After removing 114 duplicates, 1560 records were initially screened based on title and Following inclusion and exclusion criteria, 14 articles were incorporated in the structured review and a total of 47 in the extended review. The extended literature review identified 33 additional articles examining aspects of benefits that did not fall under the pre-established inclusion and exclusion criteria used in the structured review, such as health benefits and other social parameters associated with urban green spaces. The selected studies were allocated in five principal groups according to study types: three of the them consisted of studies employing “willingness to pay” (WTP) methods, five were based on property values, two studies assigned monetary values, while another two assigned CO2 values, and, finally, two studies were based on qualitative criteria. The results indicated benefits to citizens and increased welfare levels gained by the existence of urban green areas. The conducted review revealed a number of findings and recommendations that could direct future research and urban policy. Those hints could assist local authorities as well as stakeholders in order to measure and assess the benefits of green spaces and urban parks and promote measures and programs to assist their further deployment.

Although epigenetic modifications have been intensely investigated over the last decade due to their role in crop adaptation to rapid climate change, it is unclear which epigenetic changes are heritable and therefore transmitted to their progeny. The identification of epigenetic marks that are transmitted to the next generations is of primary importance for their use in breeding and for the development of new cultivars with a broad-spectrum of tolerance/resistance to abiotic and biotic stresses. In this review, we discuss general aspects of plant responses to environmental stresses and provide an overview of recent findings on the role of transgenerational epigenetic modifications in crops. In addition, we take the opportunity to describe the aims of EPI-CATCH, an international COST action consortium composed by researchers from 28 countries. The aim of this COST action launched in 2020 is: (1) to define standardized pipelines and methods used in the study of epigenetic mechanisms in plants, (2) update, share, and exchange findings in epigenetic responses to environmental stresses in plants, (3) develop new concepts and frontiers in plant epigenetics and epigenomics, (4) enhance dissemination, communication, and transfer of knowledge in plant epigenetics and epigenomics.

Parsley (Petroselinum crispum) aromatic, edible leaves are used fresh or dried as a herb, but also for their pharmaceutical properties. Given the profound concern to high nutritious and pharmaceutical value of superior plant’s germplasm, a survey is presented in this study on the phenotypic, genetic and phytochemical characterization of fifteen Greek parsley landraces in comparison to nine commercial cultivars, all grown under the same conditions in Greece. Our data reported high differences between the Greek landraces and most of the commercial cultivars in a majority of morphological traits investigated according to the International Union for the Protection of New Varieties of Plants descriptors list. The genetic diversity of all landraces and commercial cultivars were investigated using Inter Simple Sequence Repeat and Amplified Fragment Length Polymorphism molecular markers. The percentage of polymorphic loci was 63.83 % for the cultivars, and all loci were polymorphic (100 %) for the Greek landraces, while considerably higher values of unbiased haploid gene diversity were revealed in the landraces compared with the commercial cultivars. The essential oil yield of the landraces and cultivars of parsley studied ranged from 0.11−0.26 mL 100 g−1 leaf FW. The major compounds in the parsley essential oils as determined by gas-chromatography were α-pinene (0.6–11.8%), β-pinene (0.2–8.2%), myrcene (1.3–13.5%), β-phellandrene (9.6–39.1 %), terpinolene (1.4–8.9 %), 1, 3, 8-p-menthatriene (0.1–43.4 %), cis-carveol (0.2–8.1 %), iso-dihydro carveol acetate (0.2–6.9 %), myristicin (0.51–44.4%) and apiole (0.01–35.2 %). According to the targeted liquid chromatographic analysis coumarin derivatives, hydrocinnamic acids, flavanones, flavones and flavonols were identified in parsley methanolic extracts. Flavones were represented by apigenin and luteolin derivatives, and flavonols by kaempferol, quercetin, galangin and morin. Apiin was the major flavone in all parsley samples ranging from 1732.57 to 3676.43 mg 100 g -1 dry weight. The wide variation in phenotypic, genetic and phytochemical profiles observed for the landraces, indicate that the Greek germplasm collection could serve as an important source of genetic material for plant breeding and selection towards the development of new cultivars with superior traits regarding their aroma quality and polyphenolic content but also to support ongoing studies on flavonoid biosynthesis in this culinary herb.

Sweet cherry germplasm contains a high variety of phenotypes which are associated with fruit size and shape as well as sugar content, etc. High phenotypic variation can be a result of genetic or epigenetic diversity that may interact through time. Recent studies have provided evidence that besides allelic variation, epiallelic variation can establish new heritable phenotypes. Herein we conducted a genetic and an epigenetic study (using amplified fragment length polymorphism (AFLP) and methylation-sensitive amplified polymorphism (MSAP) markers, respectively), accompanied by phenotypic traits correlation analysis in sweet cherry gene pools. The mean genetic diversity was greater than the epigenetic diversity (hgen = 0.193; hepi = 0.185), while no significant relationship was found between genetic and epigenetic distance according to a Mantel test. Furthermore, according to correlation analyses our results provided evidence that epigenetic diversity in predefined populations of sweet cherry had a stronger impact on phenotypic traits than their rich genetic diversity.

Motivation Trait variation within species can reveal plastic and/or genetic responses to environmental gradients, and may indicate where local adaptation has occurred. Here, we present a dataset of rangewide variation in leaf traits from seven of the most ecologically and economically important tree species in Europe. Sample collection and trait assessment are embedded in the GenTree project (EU‐Horizon 2020), which aims at characterizing the genetic and phenotypic variability of forest tree species to optimize the management and sustainable use of forest genetic resources. Our dataset captures substantial intra‐ and interspecific leaf phenotypic variability, and provides valuable information for studying the relationship between ecosystem functioning and trait variability of individuals, and the response and resilience of species to environmental changes. Main types of variable contained We chose morphological and chemical characters linked to trade‐offs between acquisition and conservation of resources and water use, namely specific leaf area, leaf size, carbon and nitrogen content and their ratio, and the isotopic signature of stable isotope 13C and 15N in leaves. Spatial location and grain We surveyed between 18 and 22 populations per species, 141 in total, across Europe. Time period Leaf sampling took place between 2016 and 2017. Major taxa and level of measurement We sampled at least 25 individuals in each population, 3,569 trees in total, and measured traits in 35,755 leaves from seven European tree species, i.e. the conifers Picea abies, Pinus pinaster and Pinus sylvestris, and the broadleaves Betula pendula, Fagus sylvatica, Populus nigra and Quercus petraea. Software format The data files are in ASCII text, tab delimited, not compressed.

During recent centuries, cultivated olive has evolved to one of the major tree crops in the Mediterranean Basin and lately expanded to America, Australia, and Asia producing an estimated global average value of over USD 18 billion. A long-term research effort has been established with the long-term goal to preserve biodiversity, characterize agronomic behavior, and ultimately utilize genotypes suitable for cultivation in areas of unfavorable environmental conditions. In the present study, a combination of 10 simple sequence repeat (SSR) markers with the classification binary tree (CBT) analysis was evaluated as a method for discriminating genotypes within cultivated olive trees, while Olea europaea subsp. cuspidata was also used as an outgroup. The 10 SSR loci employed in this study, were highly polymorphic and gave reproducible amplification patterns for all accessions analyzed. Genetic analysis indicated that the group of SSR loci employed was highly informative. A further analysis revealed that two sub populations and pairwise relatedness gave insight about synonymies. In conclusion, the CBT method which employed SSR allelic sizes proved to be a valuable tool in order to distinguish olive cultivars over the traditional unweighted pair group method with the arithmetic mean (UPGMA) algorithm. Further research which will combine phenotyping characterization of olive germplasm will have the potential to enable the utilization of existing, and breeding of new, superior cultivars.

Global DNA methylation changes in response to recurrent drought stress were investigated in two common Greek Medicago sativa L. varieties (Lamia and Chaironia-Institute of Ιndustrial and Forage Crops). The water deficit was implemented in two phases. At the end of the first phase, which lasted for 60 days, the plants were cut at the height of 5 cm and were watered regularly for two months before being subjected to the second drought stress, which lasted for two weeks. Finally, the following groups of plants were formed: CC (controls both in phase I and phase II), CD2 (Controls in phase I, experiencing drought in phase II), and D1D2 (were subjected to drought in both phase I and phase II). At the end of phase II, samples were taken for global DNA methylation analysis with the Methylation Sensitive Amplification Polymorphism (MSAP) method, and all plants were harvested in order to measure the fresh and dry weight of roots and shoots. The variety Lamia responded better, especially the D1D2 group, compared to Chaironia in terms of root and shoot dry weight. Additionally, the shoots of Lamia had a constant water status for CD2 and D1D2 group of plants. According to DNA methylation analysis by the MSAP method, Lamia had lower total DNA methylation percentage after the second drought episode (D1D2) as compared to the plants CD2 that had experienced only one drought episode. On the other hand, the total DNA methylation percentage of Chaironia was almost the same in plants grown under recurrent drought stress conditions compared to control plants. In conclusion, the decrease of DNA methylation of Lamia stressed plants probably indicates the existence of an epigenetic mechanism that may render drought tolerance.

In the main distribution area the genetic pattern of silver birch is dominated by two haplotypes: haplotype A located in the western and north-western Europe, and haplotype C in eastern and southeastern Europe, characterized by high levels of neutral genetic variability within populations, and low differentiation among populations. Information about the amount and structure of genetic variation in the southern marginal areas, representing rear populations left during the expansion of this species from southern glacial refugia, are lacking. The general aim of the study was to investigate the existence of the climatic characteristics typical of the environmental niche of the species, jointly to genetic organization, variation and gene flow, in marginal populations on the Italian Apennines and Greek Southern Rhodope and compare them with populations of the southern part of the main distribution range on the Alps and Balkans. Genetic analysis was performed using nuclear microsatellites loci on 311 trees sampled from 14 populations. Environmental analysis was performed on the multivariate analysis of derived climatic variables. The allelic pattern was analyzed to assess genetic diversity, population diversity and differentiation, population structure and gene flow. The geographic and environmental peripherality did not always match, with some Apennine sites at higher elevation enveloped in the environmental niche. In the peripheral populations on the Apennines, we observed a lower genetic diversity and higher differentiation, with evident genetic barriers detected around these sites. These characteristics were not shown in the marginal Greek populations. Unexpectedly, the southern Italian marginal populations showed genetic links with the Greek and central area of the distribution range. The Greek populations also showed evident gene flow with the Alpine and Balkan areas. The disparity of results in these two marginal areas show that it is not the geographic peripherality or even the ecological marginality that may shape the genetic diversity and structure of marginal populations, but primarily their position as part of the continuous range or as disjunct populations. This outcome suggests different considerations on how to manage their gene pools and the role that these rear populations can play in maintaining the biodiversity of this species.

Novel primary sources of one of the world’s leading anticancer agent, paclitaxel, as well as of other antineoplastic taxanes such as 10-deacetylbaccatin-III, are needed to meet an increasing demand. Among the Taxus species the promise of Taxus baccata L. (European or English yew) has been documented. In this study, the metabolite analysis of two marginal T. baccata populations in Greece (Mt. Cholomon and Mt. Olympus), located at the southeastern edge of the species natural distribution, are being explored. A targeted liquid chromatography – mass spectrometry (LC-MS/MS) analysis was used to determine the content of 10-deacetylbaccatin III, baccatin III, 10-deacetyltaxol, paclitaxel and cephalomannine in the needles of each of the populations from three sampling periods (spring, summer and winter). This is the first survey to generate a taxane targeted metabolite data set, since it derives from Hellenic natural populations that have not been explored before. Furthermore, it has used an extensive sample design in order to evaluate chemodiversity at the population level. The analysis revealed significant levels of chemodiversity within and among the investigated populations and significant seasonal variation that could be exploited for the selection of superior germplasm native to Greece, for yew plantations and further exploitation which is necessary for the production of important taxanes.

The Mediterranean hot spot includes numerous endemic and socio-economically important plant species seriously threatened by climate change and habitat loss. In this study, the genetic diversity of five populations of Cicer graecum, an endangered endemic species from northern Peloponnisos, Greece and a wild relative of the cultivated Cicer arietinum, was investigated using inter-simple sequence repeats (ISSRs) and amplified fragment length polymorphism (AFLP) markers in order to determine levels and structure of genetic variability. Nei’s gene diversity by ISSR and AFLP markers indicated medium to high genetic diversity at the population level. Moreover, AMOVA results suggest that most of the variation exists within (93 % for AFLPs and 65 % for ISSRs), rather than among populations. Furthermore, Principal Component Analysis based on ISSRs positively correlated the genetic differentiation among the populations to the geographic distances, suggesting that the gene flow among distant populations is limited. The ecological adaptation of C. graecum populations was also investigated by correlation of their genetic diversity with certain environmental variables. Aridity arose as the dominant factor positively affecting the genetic diversity of C. graecum populations. We modelled the realized climatic niche of C. graecum in an ensemble forecasting scheme under three different global circulation models and two climate change scenarios. In all cases, a severe range contraction for C. graecum is projected, highlighting the high extinction risk that is probably going to face during the coming decades. These results could be a valuable tool towards the implementation of an integrated in situ and ex situ conservation scheme approach for activating management programmes for this endemic and threatened species.

Seed (endocarp) morphology is useful for genotype discrimination and cultivar classification. Over a 20-year period, 504 olive trees (Olea europaea subsp. europaea) previously assigned to different cultivars originating from Greece (n = 37), Spain (n = 2), and Italy (n = 2) as well as one accession of Olea europaea subsp. cuspidata were evaluated employing 11 endocarp morphological markers and 9 SSR markers. A matrix of 42 morphotypes in total was subjected to classification binary tree (CBT) analysis. In addition, cultivars were fingerprinted employing 9 microsatellite (SSR) markers and placed on a similarity dendrogram. All 41 olive cultivars and one accession of Olea europaea subsp. cuspidata employed in the present study yielded different morphological profiles produced by the 11 endocarp traits. In the resulting CBT, the total reduction in error, that is, the total information in the set of all 42 morphotypes, was 100%. This meant that the set of 11 morphological characters—having 28 different states in all—was sufficient to remove all data noise and to correctly classify all examined olive cultivars. In addition, all olive cultivars were successfully discriminated by the 9 SSR markers employed. It is suggested that cultivars with large seeds—and concomitantly large fruits—are more distant from the wild forms and probably more evolved compared to cultivars with small seeds. In corroboration to the above, based on seed shape, some of the olive cultivars showed high resemblance to wild olives leading thus to the hypothesis that they were produced or selected during the early ages of olive domestication.

In the present paper we studied the genetic diversity and genetic structure of five Norway spruce (Picea abies (L.) Karsten) natural populations situated in Serbia, belonging to the southern lineage of the species at the southern margin of the species distribution range. Four populations occur as disjunct populations on the outskirts of the Dinaric Alps mountain chain, whereas one is located at the edge of Balkan Mountain range and, therefore, can be considered as ecologically marginal due to drier climatic conditions occurring in this region. Due to the negative effect of biotic and abiotic stress factors, the sustainability of these populations is endangered, making conservation of their genetic resources one of the key measures of Norway spruce persistence in Serbia under climatic changes. The insight on genetic diversity and genetic structure of the studied spruce populations can provide the information required for the initiation of programs aimed at the conservation and utilization of spruce genetic resources at the rear edge of species environmental limits. Norway spruce genetic variation and population genetic structure were estimated using eight EST-SSR markers. The results showed that mean expected heterozygosity was 0.616 and allelic richness 10.22. Genetic differentiation among populations was low (Fst = 0.007). No recent bottleneck effect or isolation by distance were detected. Bayesian clustering, obtained with STRUCTURE, grouped the populations into two genetic clusters, whereas UPGMA analysis distinguished three main groups approximately in line with the geographic area of occurrence. Based on the study results and the EUFORGEN Pan-European strategy for genetic conservation of forest trees, the establishment of additional dynamic gene conservation units must be considered in Serbia in order to protect the adaptive and neutral genetic diversity of the species.

The different levels of biodiversity (genetic diversity, species diversity, ecosystem diversity) present in Greece are introduced, quantified, where possible, and analysed in comparison to the rest of the European continent and internationally. Greece ranks third and fourth regarding key biodiversity areas in Europe and Mediterranean Basin respectively and first in the number of species per unit area. The genetic diversity and differentiation in natural ecosystems and especially in forest tree species is very high. For a number of species (e.g. in chestnut) a significant portion of their total European genetic diversity is present in Greece and some metrics of genetic diversity parameters present high values when compared to European and world-wide average values. Nevertheless, the conservation of biodiversity has insofar focused at the ecosystem level. About one-third of the country land mass is under some form of biodiversity protection (27% included in the Natura 2000 network), however the forest genetic resources protection lags behind as officially only 5 species and 15 populations are part of the European Forest Genetic Resources Network. Overall, the richness for biodiversity in Greece is almost irreversibly proportional to the stage of its protection, especially at the genetic resource level.

Forest tree genetic monitoring and conservation are of the utmost significance for the persistence of natural forests. Genetic conservation aspires to guard and maintain genetic diversity which is crucial for safeguarding species adaptive potential. Genetic monitoring is the quantification of time-based alterations in population genetic structure and diversity which expose processes that preserve genetic variation in nature, pioneering prognosis and assisting in defining instruments for forest genetic resource management. Genetic monitoring is founded on the geneecological approach and therefore the proposed indicators are linked to the evaluation of genetic variation, genetic drift, gene flow, mating systems and natural selection. The development of genetic baseline data for the application of genetic monitoring in forest conservation areas in Greece is presented as a case study.

The phenotypic and genetic analysis of apple (Malus × domestica Borkh) genotypes is essential for breeding species. Information on the morphology and genetic structure of apple offers significant help for germplasm maintenance and selection of suitable material to breed superior cultivars. This study shows the results of an investigation on the morphology and the genetic diversity for 19 apple cultivars, which are preserved in an ex situ collection in Naoussa, Central Macedonia, Greece. Information was recorded over a 5-year period for 47 traits describing plant morphology and phenotype, as well as leaf and fruit quality. Data were analyzed using the principal component analysis (PCA) method. The Euclidean distance metric and the Ward’s agglomeration method were used in an unsupervised hierarchical cluster analysis of all cultivars. The cultivars were grouped into four main clusters, suggesting that the characterized apple collection has a high potential for specific breeding goals. Furthermore, the cultivars were genotyped using seven microsatellite primers. Moderate levels of polymorphism were detected, and 38 distinctive alleles (5.4 alleles per primer pair) were identified. Both multivariate clustering approach (phenotypic data) and the genetic distance clustering approach (genetic data) grouped the apple cultivars according to their type. Hence, these data could be used for protection or patenting processes of existing or new apple cultivars carried out by the EU-Community Plant Variety Office.

To further understand the impact of grafting on fruit characteristics and to comprehend the mechanisms involved in graft-induced changes we studied homo- and hetero- grafted Cucurbita pepo cultivars (cv.) that vary in fruit size and shape. C. pepo cv. ‘Munchkin’ and cv. ‘Big Moose’ as well as cv. ‘Round green’ and cv. ‘Princess’ were homo-grafted and reciprocally hetero-grafted. The results show significant changes in fruit size when ‘Big Moose’ was grafted onto ‘Munchkin’ rootstocks in comparison to homo-grafted controls. Statistically significant changes were also observed in fruit shape when cv. ‘Princess’ was grafted on cv. ‘Round green’. This is the first report of such phenotypic changes after intra-species/inter-cultivar grafting in Cucurbitaceae. Additionally, we found significant changes in (i) secondary metabolite profile, (ii) global DNA methylation pattern and (iii) miRNA expression patterns in grafted scions and (iv) DNA methylation on graft-induced phenotypic changes in grafted plants. Our results contribute to further understanding graft-induced effects on fruit morphology in intra-species grafting. Furthermore, our results pave the way for understanding the role of phenolic metabolites and epigenetic molecular mechanisms on the phenotypic changes recorded.

Foods based on Olea europaea are of substantial importance for Mediterranean people. The association between olive products with great civilizations emphasizes the role that played the olive tree products and especially the olive oil. This generated the need for authentication, quality control and traceability of olive products. The physicochemical and sensory analysis methods, both classical (discrimination, ordination, classification) and novel (artificial neural networks, fuzzy logic, expert systems, decision trees, support vector machines) supplemented with molecular marker techniques (SSR, AFLP, RAPD), generated the need for effective multivariate analytical methods. These mathematically complex methods are greatly needed in the detection of adulterations of oil products and particularly for olive oil. The lack of mathematical symbolism and jargon is believed to make the text attractive to all potential workers in the field and help them improve the already low level of adulterations and augment the quality control databases for Mediterranean olive products. Practical applications In this review, multivariate methods applied until now in chemometrics supplemented with molecular methods of olive‐based products were presented. Data processing in chemometris and molecular methods is an important issue in order to examine, explain, and evaluate such priorities of olive oil‐based products. This review will facilitate researches to select the best suitable statistic model or equation regarding their hypothesis and use the most appropriate method in order to improve the low level of adulterations and augment in the quality control databases for Mediterranean olive products.
