Figure 1.
Characteristics of genetic origin, selection signatures, and introgression of weedy rice. (a) Summary of the genomic composition of weedy rice populations worldwide. The majority of weedy rice populations are derived from domesticated indica, japonica, and aus genetic backgrounds, represented by blue, brown, and purple colors, respectively. Weedy rice populations exhibiting wild introgressions are indicated in green, while those resulting from admixture between indica and aus are depicted with a bidirectional arrow. The percentage values represent the proportion of wild rice ancestry present in weedy rice genomes. (b) A comparison of changes in genetic diversity for both genome-wide and target genes during the processes of rice domestication and feralization. (c) A schematic illustration highlighting the multiple independent origins of weedy rice and the role of multi-way introgressions in facilitating its adaptations.
