摘要： 水稻小穗具确定性，一个小穗内只包含一个可育的小花。本文报道一个多小花小穗突变体，其一个小穗内出现两朵及以上小花，暗示小穗分生组织确定性的丢失；另外，这些小花的花器官也表现不正常，包括外稃的伸长、浆片的缺失和雄蕊的减少。遗传分析表明该突变性状受1个隐性单基因控制，暂被命名为multi-floret 1 (mf1)。利用群体分离分析法(bulked segregation analysis, BSA)，MF1基因被定位在第3染色体上SSR标记PSSR3和RM7576之间，物理距离大约为34 kb，包含4个候选基因。研究结果为MF1基因的图位克隆和功能研究奠定了基础。

Abstract:  Rice has a determinate spikelet producing a fertile floret above two sterile lemmas. In this study, we reported a multi-floret 1 (mf1) mutant, in which spikelet lost the determinacy and produced two or more florets in an alternate phyllotaxy above sterile lemmas. In addition, all the florets showed the defects of floral organs development, such as the elongated leafy lemma, and decreased lodicule/stamen. Genetic analysis indicated that the mf1 trait is controlled by a single recessive gene. By bulked segregation analysis (BSA) and rice SSR molecular maker, the mf1 locus was located between PSSR3 and RM7576 on chromosome 3 with a 34 kb physical distance containing four annotated genes. This result provided a foundation of map-based cloning and function analysis of MF1 gene.
