Fig. 3: COG1 is selected during japonica rice domestication.

a The three COG1 haplogroups identified in 67 representative rice accessions. The Nipponbare genome sequence was used as a reference. b Phylogenetic tree showing the relationships of COG1 haplotypes. Phylogenetic tree was constructed using the sequences of COG1 in 67 representative rice accessions. c Nucleotide polymorphism and neutrality tests for COG1 in the 67 representative rice accessions. S: Number of sample. h: Number of haplotypes. π: Average number of pairwise nucleotide differences per site calculated on the silent sites. D: Tajima’s D value. d The within population selection signal value (SweeD) of the 500-kb region flanking COG1. See also Supplementary Data 2 and 3.
