Abstract
Mutations that result in plant male sterility provide means not only to probe reproductive development but also to facilitate commercial heterosis application and hybrid seed production. In this study, we report a novel male sterility gene, ms91(t), in a spontaneous mutant line (SH38) from a Chinese rice cultivar (Oryza sativa subsp. japonica ‘Jijing14’). The sterility of SH38 was studied by examining its progenies derived from crosses with 6 japonica cultivars. Corresponding F2 populations were obtained by selfing each of the 6 F1s and a backcross population was produced by crossing SH38 to the F1 of SH38 × C18. Our results revealed that SH38 has normal agronomic traits but produces no pollen grains. Segregations of male-sterile and male-fertile progenies in the F2 and backcross populations fit well with ratios of 3:1 and 1:1, respectively, indicating that ms91(t) is a single recessive gene. Amplified fragment length polymorphism (AFLP) analysis of SH38 and Jijing14 plants showed the presence of a unique band in SH38. Simple sequence repeat (SSR) analysis of the bulked and individual progenies of the F2 population of SH38 × C18 showed linkage of ms91(t) with the SSR marker RM5853 on chromosome 1. Subsequently, ms91(t) was fine-mapped to the interval between markers RM7075 (3.75 cM) and RM5638 (3.57 cM). Our results would facilitate the isolation of ms91(t) and male sterility in heterosis application.Keywords
