摘　　要：控制成花的各基因在植物生长过程中具有重要的作用。FLC是拟南芥中抑制成花的基因,通过负调控FLC的转录及蛋白表达水平,促进拟南芥的某些晚花生态型和晚花突变体开花。研究发现,FLC的表达水平与植株低温处理的时间呈数量关系,低温处理时间越长,FLC的表达越弱。介绍了拟南芥FLC基因的分子特征以及基因表达被抑制的分子机理及相关内容。Various flowering-related genes play important roles as developmental regulators in plants. FLC gene is an inhibitor of flowering in Arabidopsis. It can promote flowering in some late-flowering ecotypes and many late-flowering mutants to decrease the level of FLC transcription and expression in the plant. There is a quantitative relationship between the duration of cold treatment and the level of FLC expression. The longer cold treatment time is, and the weaker level of FLC expression is. The molecular-characteristics and expression inhibition mechanism of FLC gene in Arabidopsis thaliana were introduced in detail.
