摘要: By nitrogen ion implanting, we obtained a semi-dwarf mutant from a japonica rice cultivar Y98148, designated as Y98149. The genetic analysis of Y98149 indicated that the semi-dwarf phenotype was controlled by a single dominant gene, Sdd(t). We show that Y98149 reduced plant height mainly via inhibiting the first, second and third internode elongation. Based on this dwarfing pattern, the mutant could be grouped into dn-type dwarf defined by Takeda [Gamma Field Symp. (1977) Vol. 16, PP. 1-18]. In addition, the Sdd(t) gene was sensitive to gibberellin (GA) based on the response to extraneous GA(3) and the quantitative determination of endogenous GA(1) and GA(4). To map the Sdd(t) gene, we tested molecular markers by bulk segregant analysis. The Sdd(t) gene was localized to a 6.4 cM-interval on the short arm of chromosome 6, flanked by two sequence-tagged site markers S9 and S13.
