Call of the wild rice: Oryza rufipogon shapes weedy rice evolution in Southeast Asia.

ABSTRACT: Agricultural weeds serve as productive models for studying the genetic basis of rapid adaptation, with weed-adaptive traits potentially evolving multiple times independently in geographically distinct but environmentally similar agroecosystems. Weedy relatives of domesticated crops can be especially interesting systems because of the potential for weed-adaptive alleles to originate through multiple mechanisms, including introgression from cultivated and/or wild relatives, standing genetic variation, and de novo mutations. Weedy rice populations have evolved multiple times through dedomestication from cultivated rice. Much of the genomic work to date in weedy rice has focused on populations that exist outside the range of the wild crop progenitor. In this study, we use genome-wide SNPs gene
