Allelic effects and distribution of GW5/GSE5. Alleles of GW5/GSE5 (a); comparisons of grain length (b), grain width (c) and length/width ratio (d) for the three GW5/GSE5 alleles; the distribution of GW5/GSE5 alleles (e) in international indica accessions and Guangdong Simiao varieties; * A pangenome was used as the reference genome (Wang et al. 2022); letters above the bars are ranked by Duncan’s test at P < 0.05; different letters indicate significant differences; red rectangle box: major allele in Guangdong Simiao varieties; scale bar: 100 bp
