Fine genetic mapping of v-1 gene. (a) Framework map of v-1 gene with 148 RILs. Numbers above the chromosome are genetic distance in centiMorgan (cM); (b) Fine mapping narrowed the v-1 locus into a 50.4 kb region flanked with markers v1SSR8 and CAPs15 based on 1800 F₂ plants. Numbers above the chromosome are recombinants at each interval; (c) Six genes were predicted in the 50.4 kb region; (d) Structure of CsaCNGCs candidate gene. Black boxes are exons; white boxes are UTRs; and black lines indicate introns; and (e) Alleles of a SNP (A/T) in the promoter region of the CsaCNGCs candidate gene in 9110G, 9110Gt, 9930 and 3 recombinant plants.
