Seed priming, traditionally viewed as a method for enhancing crop resilience to abiotic stress, has evolved into a multifaceted agronomic strategy. This review synthesizes the current findings demonstrating that priming influences plant development, metabolic regulation, and yield enhancement even under optimal conditions. By covering a wide range of crops, including cereals (e.g., wheat, maize, rice, and barley) as well as vegetables and horticultural species (e.g., tomato, carrot, spinach, and lettuce), we highlight the broad applicability of priming across agricultural systems. The underlying mechanisms include hormonal modulation, altered source–sink dynamics, accelerated phenology, and epigenetic memory. Various priming techniques are discussed, including hydropriming, osmopriming, biopriming, chemopriming, and nanopriming, with attention to their physiological and molecular effects. Special focus is given to the role of seed priming in advancing climate-smart and precision agriculture. By shifting the narrative from stress mitigation to holistic crop performance optimization, seed priming emerges as a key tool for sustainable agriculture in the face of global challenges.

Polyploidy is a powerful mechanism driving genetic, physiological, and phenotypic changes among cytotypes of the same species across both large and small geographic scales. These changes can significantly shape population structure and increase the evolutionary and adaptation potential of cytotypes. Alyssum moellendorfianum, an edaphic steno-endemic species with a narrow distribution in the Balkan Peninsula, serves as an intriguing case study. We conducted a comprehensive analysis of genetic diversity and population structure across the species’ range, employing an array of genetic techniques (nuclear microsatellites, amplified fragment length polymorphisms, and plastid DNA sequences), flow cytometry (FCM), morphometry, and pollen analysis. The study reveals two genetic lineages: spatially distributed diploid and tetraploid cytotypes. Clear divergence between diploids and tetraploids was shown by AFLP, while plastid DNA sequences confirmed private haplotypes in each of the studied populations. Higher genetic diversity and allelic richness following the north-south pattern were documented in tetraploids compared to diploids, as indicated by nuclear microsatellites. Morphometric analysis via principal component analysis (PCA) and canonical discriminant analysis (CDA) did not reveal any divergence between diploid and tetraploid cytotypes. Nonetheless, a distinction in pollen size was clearly observed. The results suggest an autopolyploid origin of tetraploids from diploid ancestors. Despite the population fragmentation in a very small geographic range, these populations harbour high genetic diversity, which would allow them to remain stable if natural processes remain undisturbed.

In the present study modern technology of DNA extraction and automatic genotyping was applied in Bosnian and Herzegovinian autochthonous horse breed by using 17-Plex horse genotyping kit. The study was aimed at investigating usefulness of the 17-plex STR Kit for Bosnian mountain horse genotyping and establishing highly useful microsatellite markers system for genetic diversity studies in Bosnian mountain horse breed. Genomic DNA was extracted from whole blood collected from 22 unrelated Bosnian mountain horse specimens. A total of 95 alleles were detected. Average number of detected alleles per locus was 5.588, varying from 3 (HTG7) to 10 (ASB17). Average effective number of alleles was 3.603, fluctuating from 1.789 (HMS7) to 5.728 (HMS2). The observed heterozygosity ranged from 0.136 (HMS3) to 0.909 (ASB2) with a mean of 0.631. The results indicate that the studied population originates from the appropriate number of parent generations. The mean expected heterozygosity was 0.690, varying from 0.441 (HMS7) to 0.853 (ASB17) indicating high genetic variability within Bosnian mountain horse population. The PIC values ranged from 0.409 (HMS7) to 0.837 (ASB17) with a mean of 0.643, suggesting that 94.12% markers were quite informative in terms of their suitability for genetic diversity studies .The most polymorphic locus was HMS2 and the least polymorphic locus was HMS7. The inbreeding coefficient ranged from -0.030 (HMS7) to 0.807 (HMS3) with a mean of 0.077. Inbreeding coefficient values indicated no shortage of heterozygotes in Bosnian mountain horses. Deviation from Hardy-Weinberg equilibrium (p<0,05) was found in three loci (HTG10, HMS3 and ASB17). The applied set of 17 microsatellite markers proved to be sufficiently specific for use in genotyping of Bosnian mountain horse. Considering the values of HO, HEand PIC over 0.6, five microsatellite markers system (HTG4, AHT4, AHT5, ASB2, HMS2) is considered to be highly useful for genetic diversity studies in Bosnian mountain horse breed.
