Article Synopsis
- High-depth whole-genome resequencing of 53 fig tree genotypes revealed over 5.5 million genetic variants, creating a detailed genetic map of the species.
- The study identified three geographical groups of fig trees, analyzing their genetic diversity, structural variants, and potential impacts on plant health and metabolism.
- Genome-wide association studies linked specific genetic markers to important fruit quality traits, opening avenues for future research and improvements in fig agriculture.
The genetic relationships between Greek wild olive tree populations and cultivars were investigated. A total of 219 wild genotypes and 67 cultivar genotypes were analyzed by employing 10 SSR markers. Data evidenced that the wild populations exhibited high levels of genetic diversity and exclusively host 40% of the total number of alleles detected.

- The olive tree is a key species in the Mediterranean, with a rich history of domestication and now a better understanding of its genomic diversity thanks to whole genome assemblies and annotations.
- Recent research created a comprehensive genomic variation map for 89 olive tree genotypes from across the Mediterranean, highlighting genetic diversity and relationships among different varieties.
- The study also identified candidate genes linked to important traits like olive oil quality and fruit yield, paving the way for future breeding and insights into olive tree biology.
Evaluation of a dill ( L.) gene bank germplasm collection using multivariate analysis of morphological traits, molecular genotyping and chemical composition to identify novel genotypes for plant breeding.

Dill ( L.) is an aromatic herb widely used in the food industry, with several commercial cultivars available with different qualitative characteristics. Commercial cultivars are usually preferred over landraces due to their higher yield and also the lack of improved landraces than can be commercialized.

The first objective of this study was to evaluate eighteen genotypes derived from different regions of Greece regarding the phytochemical contents of their soluble extracts in total phenolics, total flavonoids, and individual polyphenols as determined by LC-MS analysis, as well as ascorbic acid content and their antioxidant capacity as determined by different assays, including ABTS (2,2-azino-bis-3-ethylbenzothiazoline-6-sulfonic acid), DPPH (2,2-diphenyl-1-picrylhydrazyl radical scavenging activity), and FRAP (ferric reducing antioxidant power) assays.
