开花的时间对植物的繁殖成功很重要。在这里，我们描述了一个新的MADS盒基因，FLOWESTERN LOCUS M（FLM），这是参与从营养向生殖发育的过渡的鉴定和表征。FLM的氨基酸序列与FLC相似，FLC是另一个参与开花时间控制的MADS盒基因。flm突变体在诱导光周期和非诱导光周期下均提早开花，且开花时间对FLM剂量敏感。FLM过表达产生晚花植物。因此，FLM作为开花的抑制剂。FLM在细胞分裂的区域如根和茎的顶端区域和叶原基中表达。
The timing of flowering is important for the reproductive success of plants. Here we describe the identification and characterization of a new MADS-box gene, FLOWERING LOCUS M (FLM), which is involved in the transition from vegetative to reproductive development. FLM is similar in amino-acid sequence to FLC, another MADS-box gene involved in flowering-time control. flm mutants are early flowering in both inductive and non-inductive photoperiods, and flowering time is sensitive to FLM dosage. FLM overexpression produces late-flowering plants. Thus FLM acts as an inhibitor of flowering. FLM is expressed in areas of cell division such as root and shoot apical regions and leaf primordia.
