| 摘 要： | 植物开花是从营养生长到生殖状态的重要发育转变，是多种内在因子和环境因素共同作用的结果。在拟南芥开花调控网络中，开花抑制基因FLC处于枢纽地位。FLC的表达受许多来自环境和生长发育的信号调控，主要包括：PAF1复合体、SWR1复合体成员，FRI依赖途径、自主途径和春化作用途径基因。本文主要综述了影响FLC表达的春化相关基因及天然早花突变体的研究进展，并根据最新的研究成果提出该研究领域的研究方向和重点。

| Abstract: | Plant flowering is a crucial developmental transition from the vegetative to reproductive phase and is properly timed by a number of intrinsic and environmental cues. In the regulation network of flowering of Arabidopsis, FLC is a potent repressor of flowering. The expression of FLC is regulated by lots of factors, including endogenous cues and environmental stimuli which mainly contain： SWRlcomplex, PAFlcomplex, FRI complex, autonomous pathway and vernalization pathway genes. This paper reviews the progress of study on vernalization-related genes that regulate the expression of FLC and natural early flowering variation, and the new directions and focal points in this research field. |
