a Analysis of two key amino acids (aa) of SDR3.1 in wild rice. The red arrows mark the positions of the two key amino acids (aa102 and aa156). b Two combinations of two key aa of SDR3.1 in 28 wild rice accessions. c-d Tajima’s D and nucleotide diversity (π) for the ~2-Mb genomic region flanking SDR3.1 in the 3 K RGs; SDR3.1 is indicated by a red dashed line. e Germination rate of ZH11 and N102S 35 DAH (n = 3 independent experiments); PHS phenotypes of ZH11 and N102S 35 DAH. f Germination rate of YK17 and D156E 35 DAH (n = 3 independent experiments); PHS phenotypes of YK17 and D156E 35 DAH. g Proposed two-line model for the process of rice seed dormancy domestication. During the domestication of wild rice to Geng/japonica, Ser102 of SDR3.1 was converted to Asn102, which caused most of the dormancy lost. During the process of domestication to Xian/indica, Glu156 was converted to Asp156, which caused some of the dormancy lost. The values in parentheses indicate the average germination rate. In e, f Data are presented as the mean ± SD, and P values are indicated by two-tailed Student’s t test. Source data are provided as a Source Data file.
