Genome-wide detection of selection signals and functional validation reveals adaptive evolutionin grapevine
We identified a four-gene VsGAUT cluster that has undergone a selective sweep. Among these genes, VsGAUT24 shows differentiation between wild and cultivated grapevines, supporting its role in domestication. Functional validation further confirms the reliability of theselection signals. We also analyzed the expression patterns of GAUT gene family members andsdetermined-whichgenes"areinduced-by which treatments.
