Map-based cloning of the 637ys locus. a The 637ys locus was mapped to a region between InDel markers L1 and L2 on the short arm of the chromosome 2 (Chr.2). b The 637ys locus was narrowed down to a region between SSR markers RM110 and RM7033 using 231 F₂ plants. c The 334 kb-region contains 62 putative genes. d The candidate LOC_Os02g03330 gene is constituted by three exons and two introns, and G-to-A substitution occurred at the first nucleotide of the first intron in the 637ys mutant, the position 368 of its coding region. e 10 bp of intron sequence inserted in the cDNA sequence of OsLIL3 in the 637ys mutant. The sequences of intron and exon are shown in lower and upper case, respectively
