为了更好地了解水稻花的发育，从甲基磺酸乙酯(EMS)处理的金恢10号(Oryza sativa L.SSP)中鉴定出一个水稻花突变体。在本研究中使用的是(水稻)。在SNL突变体中，内稃获得了外皮特征，形成了额外的颖片状器官，鳞被增加和伸长，雄蕊减少，少数异常心皮形成。这些表型表明SNL参与了整个水稻花的发育。SNL定位于2号染色体上约800kb的两个简单序列重复标记RM3512和RM1342之间，并与SSR215共分离。因此，SNL基因是一个与水稻花发育相关的新基因。本研究为进一步克隆SNL基因奠定了基础，为进一步阐明水稻花发育奠定了基础。
In order to gain a better understanding of rice flower development, a rice flower mutant supernumerary lodicules (snl), which was identified from ethyl methane sulfonate (EMS)-treated Jinhui10 (Oryza sativa L. ssp. indica) was used in the present study. In the snl mutant, the palea obtained lemma identity, additional glume-like organs formed, lodicules increased and elongated, stamens decreased, and a few aberrant carpels formed. These phenotypes suggest that SNL is involved in the entire rice flower development. SNL was mapped between two simple sequence repeat markers RM3512 and RM1342 on chromosome 2, an approximate 800 kb region, and it co-segregated with SSR215. We conclude that SNL is a novel gene involved in flower development in rice. The present study will be useful for further cloning of the SNL gene, which will contribute to the elucidation of rice flower development.
