Collection description
This study analyses genetic diversification, demographic history, and evolution of various plant species by analyzing genetic markers. For Eokochia saxicola, a rare Mediterranean coastal halophyte, chloroplast and nuclear SNPs were employed. Results indicate low haplotype variation in plastid genomes, with evidence of admixture among populations and multiple colonizations. Nuclear SNPs reveal distinct genetic clusters corresponding to sampling localities, with genetic solid isolation. Additionally, a phylogenetic analysis was conducted on E. saxicola and Spirobassia hirsuta, providing new insights into genetic complexities within the Camphorosmeae, with implications for genome size evolution and phylogenetic relationships. Similarly, genomic analysis of Ophrys sphegodes identified genomic regions as candidates for pollinator- mediated evolution. Lastly, genome analysis of Phaseolus vulgaris supports a specific geographic origin for this crop, rejecting recent hypotheses and emphasizing the importance of genetic variability analysis in understanding crop evolution. Custom-designed orchid bait sets exhibit high performance in phylogenetic analysis and species identification, providing valuable tools for Orchidaceae research. This study provides a comprehensive framework of evolutionary dynamics in various plant species using advanced genetic approaches.
