Olive tree (Olea europaea L. subsp. var. europaea) is one of the most important species Mediterranean region and ancient domesticated. The availability whole genome assemblies annotations olive cultivars oleaster (O. sylvestris) has contributed to a better understanding genetic genomic differences between cultivars. However, compared other plant there still lack resources for populations that span entire region. In present study we developed complete variation map comprehensive...

The genetic relationships between Greek wild olive tree populations and cultivars were investigated. A total of 219 genotypes 67 cultivar analyzed by employing 10 SSR markers. Data evidenced that the exhibited high levels diversity exclusively host 40% number alleles detected. Inbreeding was observed within populations, probably as a consequence their fragmented spatial distribution. differentiation individuals, well low. Nevertheless, three gene pools trees detected, corresponding to...

High-depth whole-genome resequencing of 53 diverse fig tree genotypes yielded a rich dataset genetic variants. We successfully identified 5,501,460 single-nucleotide polymorphisms (SNPs) and 1,228,537 insertions deletions (InDels), providing high-density excellent-quality map the tree. also performed detailed population structure analysis, dividing into three geographical groups assessing their diversity divergence. Analysis structural variants (SVs) copy number variations (CNVs) revealed...

Dill ( Anethum graveolens L.) is an aromatic herb widely used in the food industry, with several commercial cultivars available different qualitative characteristics. Commercial are usually preferred over landraces due to their higher yield and also lack of improved than can be commercialized. In Greece, however, traditional dill cultivated by local communities. Many conserved Greek Gene Bank aim here was investigate compare morphological, genetic, chemical biodiversity twenty-two nine...

Observed (Ho) and expected (He) heterozygosity, as well allelic richness (AR) were calculated using Simple Sequence Repeats (SSR) genotyping for two important European keystone forest tree species. Abies alba Fagus sylvatica are under pressure in a large part of their distribution due to climate change. Since Greece is south-eastern limits, climatic even higher. As rear edge/peripheral populations, it harbor valuable well-adapted germplasm conditions such those central Europe by the end...

Vicia sativa L., commonly known as the common vetch, is an annual, self-pollinating legume used primarily fodder both by livestock and wildlife. Additionally, it contributes to environmental balance through nitrogen fixation improvement of soil properties. The phenotypic, genetic, metabolite variability among four advanced lines (BK45, BK29, BK23, BK27) two commercial varieties (M-6900, BI-65) V. were evaluated in order be for future breeding programs aimed at producing genetically improved...

However, genetic resources in Crete have rarely studied assessed, while chestnuts are threatened by several anthropogenic factors. This study assessed variability using 59 trees corresponding four best-known cultivars (Strovliani, Rogdiani, Koutsakera Katharokastania). (2) Materials Methods: The were...
