The effects of salt on the quality of fruits were investigated in order to compare the impact of salt on key fruit properties of the cultivated domesticated tomato species (Solanum lycopersicum) and its wild halophyte relative Solanum chilense. To this end, cherry tomato plants (S. lycopersicum var. cerasiforme) and from accession LA4107 (S. chilense) were maintained for 112 days in the absence or presence of NaCl (40 and 80 mM) in nutrient solution. Among others, salinity decreased fruit weight and increased total soluble solid (TSS) in S. lycopersicum but not in S. chilense. The fruit antioxidant capacity estimated by ferric reducing antioxidant power (FRAP) analysis was higher in S. chilense than in S. lycopersicum and increased in the former while it decreased in the latter in response to NaCl. Salinity increased the lycopene (LYC) content but decreased ß-carotene (b-CAR) concentration in the fruits of S. lycopersicum, while these compounds were not detected in the wild halophyte S. chilense. The oxidative status of salt-treated fruits was more tightly regulated in S. chilense than in S. lycopersicum. The two considered species, however, possess complementary properties and interspecific crosses may therefore be considered as a promising option for the improvement of salt-stress resistance in tomatoes.

Arrayan and peumo fruits are commonly used in the traditional medicine of Chile. In this study, the concentration of the extracts halving the bacterial viability and biofilms formation and disruption of the drug-sensitive and drug-resistant strains of Staphylococcus aureus and Pseudomonas aeruginosa was determined. The chemical composition of extracts was analyzed by high-resolution liquid chromatography coupled with mass spectrometry (U-HPLC/MS). The arrayan extract (Inhibitory concentration IC50 0.35 ± 0.01 mg/mL) was more effective than peumo extract (IC50 0.53 ± 0.02 mg/mL) in the inhibition of S. aureus planktonic cells. Similarly, the arrayan extract was more effective in inhibiting the adhesion (S. aureus IC50 0.23 ± 0.02 mg/mL, P. aeruginosa IC50 0.29 ± 0.02 mg/mL) than peumo extracts (S. aureus IC50 0.47 ± 0.03 mg/mL, P. aeruginosa IC50 0.35 ± 0.01 mg/mL). Both extracts inhibited quorum sensing in a concentration-dependent manner, and the most significant was the autoinducer-2 type communication inhibition by arrayan extract. Both extracts also disrupted preformed biofilm of P. aeruginosa (arrayan IC50 0.56 ± 0.04 mg/mL, peumo IC50 0.59 ± 0.04 mg/mL). However, neither arrayan nor peumo extracts disrupted S. aureus mature biofilm. U-HPLC/MS showed that both fruit extracts mainly possessed quercetin compounds; the peumo fruit extract also contained phenolic acids and phenylpropanoids. Our results suggested that both extracts could be used as natural antimicrobials for some skin and nosocomial infections.

This review discusses the contribution of the use of the isolated rat aorta (IRA) as a model for the evaluation of extracts and metabolites produced by plants with a vasodilator effect in animals. This model continues to be a valuable approach for the search and development of new phytochemicals consumed as medicinal plants or foods. In most cases, the sources of phytochemicals have been used in folk medicine to treat ailments that include hypertension. In this model, the endothelium is emphasized as a key component that modulates the vessel contractility, and therefore the basal tone and blood pressure. Based on the functional nature of the model, we focused on studies that determined the endothelium-dependent and -independent vasodilatory activity of phytochemicals. We describe the mechanisms that account for aorta contraction and relaxation, and subsequently show the vasoactive effect of a series of phytochemicals acting as vasodilators and its endothelium dependence. We highlight information regarding the cardiovascular benefits of phytochemicals, especially their potential antihypertensive effect. On this basis, we discuss the advantages of the IRA as a predictive model to support the research and development of new drugs that may be of help in the prevention and treatment of cardiovascular diseases, the number one cause of death worldwide.

In recent years, there has been an increasing interest in studying food and its derived ingredients that can provide beneficial effects for human health. These studies are helping to understand the bases of the ancestral use of several natural products, including native fruits as functional foods. As a result, the polyphenol profile and the antioxidant capacity of the extracts obtained from different Patagonian native berries have been described. This review aims to provide valuable information regarding fruit quality, its particular compound profile, and the feasibility of producing functional foods for human consumption to prevent disorders such as metabolic syndrome and cardiovascular diseases. We also discuss attempts concerning the domestication of these species and generating knowledge that strengthens their potential as traditional fruits in the food market and as a natural heritage for future generations. Finally, additional efforts are still necessary to fully understand the potential beneficial effects of the consumption of these berries on human health, the application of suitable technology for postharvest improvement, and the generation of successfully processed foods derived from Patagonian berries.

Fleshy fruits are characterized by having a developmentally and genetically controlled, highly intricate ripening process, leading to dramatic modifications in fruit size, texture, color, flavor, and aroma. Climacteric fruits such as tomato, pear, banana, and melon show a ripening-associated increase in respiration and ethylene production and these processes are well-documented. In contrast, the hormonal mechanism of fruit development and ripening in non-climacteric fruit, such as strawberry, grape, raspberry, and citrus, is not well characterized. However, recent studies have shown that non-climacteric fruit development and ripening, involves the coordinated action of different hormones, such as abscisic acid (ABA), auxin, gibberellins, ethylene, and others. In this review, we discuss and evaluate the recent research findings concerning the hormonal regulation of non-climacteric fruit development and ripening and their cross-talk by taking grape, strawberry, and raspberry as reference fruit species.

Using Illumina HiSeq ™ 2000 sequencing platform (100 bp double-end reads), we performed transcriptome analysis of flower (F), green (G) and pink (P) fruit stages of red raspberry. Transcriptome was obtained by the de-novo assembly of 298 Million high-quality reads through Trinity assembler, out of the 41,650 high quality transcripts, 18,171 coding sequences were successfully characterized using databases such as UniProtKB, NCBI Non-Redundant, KEGG, Gene Ontology, and InterPro-Scan. A total of 2409 transcripts were further identified as differentially expressed genes (DEGs) between the three libraries generated, and 253 DEGs were found between different fruit stages. Singular enrichment analysis of gene ontology (GO) detected an important group of DEGs over-expressed during fruit development; and associated with ethylene, auxin conjugation, abscisic acid response, brassinosteroids biosynthesis and signaling, and cell-wall disassembly processes. Our transcriptome data provides valuable insights on genes involved in the ripening process of Rubus fruit, as a representative of non-model fruit species, and may help in developing these cultivars with improved fruit quality characteristics in the years to come.

The conjugation of indole-3-acetic acid (IAA) to amino acids by indole-3-acetic acid (IAA)-amido synthetases (GH3) is an important part of auxin level regulation. However, the auxin conjugation during development of soft fruits such as raspberry is poorly understood. In this study, indole-3-acetic acid (IAA)-amido synthetases in raspberry, designated as RiGH3 (RiGH3.1, RiGH3.5 transcripts) were evaluated during fruit development of raspberry cultivar Rubus idaeus Heritage, and under IAA treatment. The results showed that before to the onset of ripening the fruit size, weight and the expression of IAA-amido synthetase RiGH3.1 transcript levels increased. Then when the fruits attain full development, fruit firmness and titratable acidity decreased, in the contrast to ethylene production and total soluble solids content increasing. However, the RiGH3.5 transcript was found to be expressed primarily in flowers. When compared to untreated control fruit, fruit treated with 1 mM of IAA at white stage, showed an increase of RiGH3.1 transcript during in-vitro assay (10 °C by 18 h). However, no significant change in the levels of RiGH3.5 was observed during IAA treatment. Multiple alignments of the full-length predicted RiGH3.1 protein sequences revealed a high sequence homology with proteins deduced sequences described for other fruit of Rosaceae species. The RiGH3.1 deduced sequence showed the presence of binding motives for IAA and aspartic acid, and indicate that the isolated sequence have the typical motives of GH3.1 protein family. These findings give new insights into the possible role of RiGH3.1 transcripts, and the IAA conjugation (in maintaining the low concentration of free IAA) during raspberry fruit ripening.

BACKGROUND Pomegranate (Punica granatum) is a non‐climacteric fruit susceptible to chilling injury (CI) at temperatures below 5 °C. To understand the influences of ethylene and modified atmosphere on CI physiological disorders of pomegranate, the exogenous ethrel (0.5, 1, and 1.5 μg L‐1) treatments, 1‐methylcyclopropene (1‐MCP) (1 μL L‐1) exposure, packaging in modified atmosphere (MAP: XTend ™ bags), a MAP/1‐MCP combination, and packaging in macro‐perforated bags (MPB) were applied. The treated fruits were cold stored (2 ± 1 °C; 85% RH) and sampled during 120 d + 3 d at 20 °C. RESULTS During cold storage CI symptoms started at 20 d in MPB and at 60 d for all exogenous ethylene treatments, being delayed to 120 d in MAP, 1‐MCP, and MAP/1‐MCP treatments. MPB and ethylene treatments induced significantly electrolyte leakage, oxidative damage, lipid peroxidation, ethylene and CO2 production and 1‐aminocyclopropane‐1‐carboxylic acid oxidase activity, without change in TSS, TA, or skin and aril colours. Conversely, MAP by itself or in combination with 1‐MCP application, effectively delayed CI symptoms. CONCLUSION During long‐term cold storage of this non‐climacteric fruit, ethrel application induce endogenous ethylene biosynthesis accelerating the appearance of CI symptoms as a contrary to observe for MAP and 1‐MCP treatments.

The arrayan berry (Luma apiculata) is a native fruit from South America that belongs to the Myrtaceae family. To elucidate and characterize the developmental process and the potential health benefits of this edible fruit, quality and physiological parameters, along with antioxidant capacity, were evaluated during four clearly defined developmental stages of the fruit in two seasons. Fruit firmness slowly decreases during fruit development, whereas the solid soluble content/titratable acidity ratio (SSC/TA) increases significantly in the final stages of development. The measurement of low respiration rates and low ethylene production during growth and ripening suggested that the arrayan berry should be classified as a non-climacteric fruit. Arrayan berries show a significant increase in their antioxidant capacity from small green to black ripe fruit. FRAP and TEAC assays showed high correlations with total polyphenolic content (TPC) during ripening and high antioxidant capacity at all fruit stages, showing greater values in ripe fruit (FRAP: 24 ± 2 and 28 ± 3 μM FeSO4/gFW; TEAC: 18 ± 2 and 20 ± 1 Eq. Trolox/gFW for each season, respectively) than those observed in the blueberry (FRAP: 10 ± 2 and 19 ± 3 μM FeSO4/gFW; TEAC: 10 ± 2 and 17 ± 3). In addition, bioactive assays using ripe fruit extracts show presence of flavonol and anthocyanins, a high ORAC value (62,500 ± 7000 μmol/gDW) and a concentration-dependent vascular protection under high glucose conditions. The results obtained show that these endemic berry fruits have a promising potential as functional food.

Red Raspberry (Rubus idaeus) is traditionally classified as non-climacteric, and the role of ethylene in fruit ripening is not clear. The available information indicates that the receptacle, a modified stem that supports the drupelets, is involved in ethylene production of ripe fruits. In this study, we report receptacle-related ethylene biosynthesis during the ripening of fruits of cv. Heritage. In addition, the expression pattern of ethylene biosynthesis transcripts was evaluated during the ripening process. The major transcript levels of 1-aminocyclopropane-1-carboxylic acid synthase (RiACS1) and 1-aminocyclopropane-1-carboxylic acid oxidase (RiACO1) were concomitant with ethylene production, increased total soluble solids (TSS) and decreased titratable acidity (TA) and fruit firmness. Moreover, ethylene biosynthesis and transcript levels of RiACS1 and RiACO1 were higher in the receptacle, sustaining the receptacle's role as a source of ethylene in regulating the ripening of raspberry.

SUMMARYFarmers around the world are concerned about the effects of human-induced salinity on crop yield and quality. Therefore, researchers are actively testing wild relatives of cultivated plants to identify candidates to improve crop performance under salt stress. A study was conducted to understand the effects of salt stress (Sodium chloride, NaCl) on cultivated tomato species (Solanum lycopersicum var. cerasiforme L.) and a wild tomato relative (Solanum chilense Dun.) from the Northern part of Chile. Plants were cultivated hydroponically under controlled environmental conditions for 112 days with nutrient solution containing 0 mM (3 dS m−1), 40 mM (6 dS m−1) and 80-mM (9 dS m−1) NaCl. Salt stress reduced the shoot biomass in S. lycopersicum but not in S. chilense. Both species were able to maintain the leaf water content; however, the cultivated S. lycopersicum showed osmotic adjustment, while S. chilense did not. Salt stress reduced the total fruit yield in S. lycopersicum based on a decrease in the mean fruit weight, but it had no impact on the number of fruits per plant. In contrast, salt stress had no significant impact on the fruit yield in S. chilense. Salt stress increased the total soluble solids content in S. lycopersicum and the titratable acidity in S. chilense. It was concluded that S. chilense displays a contrasting behaviour in response to prolonged exposure to moderate salinity compared with S. lycopersicum, and that this related species could be an interesting plant for breeding purposes.

Mountain papaya (Vasconcellea pubescens) is a climacteric fruit that develops a strong and characteristic aroma during ripening. Esters are the main volatile compounds produced by the fruit, and most of them are dependent on ethylene. As esters are synthesized through alcohol acyltransferases (AAT), a full-length cDNA (VpAAT1) was isolated that displayed the characteristic motifs of most plant acyltransferases. The full-length cDNA sequence was cloned and expressed in yeasts, obtaining a functional enzyme with high AAT activity toward the formation of benzyl acetate. The transcript accumulation pattern provided by qPCR analysis showed that the VpAAT1 gene is expressed exclusively in fruit tissues and that a high level of transcripts is accumulated during ripening. The increase in VpAAT1 transcripts in fruit is coincident with the increase in AAT activity; transcript accumulation is induced by ethylene, and it is avoided by 1-methylcyclopropene (1-MCP) treatment. The data indicate that VpAAT1 is involved in aroma formation and that ethylene plays a major role in regulating its expression.

Fragaria chiloensis is characterized for having great aroma and flavor properties. Using headspace-SPME different volatile compounds were identified and quantified during development and ripening of the fruit. The headspace was dominated by esters, butyl acetate, ethyl acetate, ethyl butanoate and ethyl hexanoate being the most abundant in fully ripe fruit. As esters are important for aroma and synthesized through alcohol acyltransferases (AAT), a full-length cDNA (FcAAT1) was isolated from F. chiloensis fruit which displayed the three motifs characteristic of most AATs. As the production of esters increased during ripening, a clear increment in FcAAT1 transcripts was observed in fruit tissue. A good correlation was found between AAT activity and the total content of esters, especially with acetates and hexanoates. Aroma-related esters displayed during ripening the same production profile as AAT activity. Therefore it can be suggested that the FcAAT1 gene may have a significant role in ester production of F. chiloensis fruit.
