图3 s2-21 在水稻第1染色体上的精细定位 A: 基因的初步定位; B: 基因的精细定位数值表示发生的交换单株个数; C: 定位区间的预测基因和突变基因; D: PLA2 基因结构, 该基因包含6个外显子和5个内含子, 箭头指示突变体的突变位点。 Fig. 3 Fine mapping of s2-21 on chromosome 1 A: primary mapping of s2-21 mutant; B: fine mapping of mutant allele region the numbers of recombination events were shown; C: the candidate region of the s2-21 gene and the predicted OFRs in this interval; D: struture of the s2-21 gene. It consists of six exons filled rectangles and five introns black line. Arrows indicate the mutation site in the s2-21 mutant. |
