Genomic Diversity and Introgression in O. sativa Reveal the Impact of Domestication and Breeding on the Rice Genome
Figure 4
Regions of introgression from temperate japonica into indica aligned with admixture mapping and association mapping p-values for amylose content.
Genome position of SNPs and introgressions indicated across the bottom; vertical grey lines indicate chromosomes; position of Waxy gene on chromosome 6 shown as vertical dashed line. (A) Horizontal grey lines indicate accessions; blue-colored regions represent introgressions (defined by ≥5 SNPs) from temperate japonica into indica; variety names (on left) colored dark blue indicate indica accessions carrying a waxy allele introgressed from temperate japonica; those without waxy introgression indicated in red. (B) Admixture mapping p-values for amylose content using the temperate japonica component in the admixed subpopulation. (C) Association mapping p-values for amylose content in all accessions using mixed model approach. Horizontal dotted lines in both (B) and (C) represent significance values of 0.05 after Bonferroni correction.
