Title：Genomic Architecture of Trait Evolution and Plant-Microbe Interactions: Lessons from Vigna for Biodiversity Research

Host：Dr. Yin-Ru Chiang

Abstract
        Legumes provide a robust framework for investigating the genomic basis of domestication and plant-microbe interactions. In particular, studies in Vigna angularis and Vigna radiata have revealed selection on seed coat pigmentation genes and variation in symbiotic efficiency, respectively, highlighting key evolutionary processes. These insights are further supported by broader investigations into plant immunity and pathogen population structure, including stomatal defense signaling and the phylogeography of bacterial pathogens. Building on these foundations, comparative and functional genomic approaches across legume lineages are enabling the reconstruction of evolutionary trajectories shaped by microbial co-adaptation. Moreover, the integration of population genomics, microbiome profiling, and archaeological data contributes to a deeper understanding of molecular adaptation. Together, these efforts establish legumes, especially Vigna spp., as a model for biodiversity, ecological resilience, and sustainable agriculture.
