【摘要】 在植物的生命周期中从营养生长到开花是发育过程的重要转折。花启动的时机对生殖生长的成功至关重要。植物开花时间突变体的获得,在揭示植物花发育的奥秘中起了十分重要的作用。本研究以模式植物拟南芥(A rabid op sis tha liana)为材料,将野生型拟南芥(Co lum b ia生态型)的种子用甲基黄酸乙酯(EM S)诱变处理,将经诱变处理的种子M1播种收获M2种子用于突变体筛选。以初生莲座叶片数作为筛选指标,筛选出一株晚花突变体,命名flx(flow ering locus x)。更多还原

【Abstract】 The transition from vegetative growth to flowering is the major developmental switch in the plant life cycle.The timing of flower initiation is critical for reproductive success.The acquisition of mutants related to flowering time played an important role in uncovering floral development.In this study,seeds of wild-type Arabidopsis thaliana（Columbia） were mutagenized with EMS,M₂ populations were screened by rosette leaf number.A late-flowering Arabidopsis mutant flx was isolated.更多还原
