摘 要 :拟南芥春化作用相关基因FLOWERING LOCUS C(FLC)属于MADS盒基因,它编码的蛋白转录因子对开花具抑制作用。春化作用通过负调控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。主要介绍了FLC基因在春化途径中的关键作用,及其春化作用通过FLC基因与其它开花途径相联系等内容。
Abstract:In Arabidopsis,the MADS-box protein encoded by FLOWREING LOCUS C(FLC) is a repressor of flowering.Vernalization promotes flowering in some late-flowering ecotypes and many late-flowering mutants by decreasing the level of FLC transcript and protein in the
