摘要
开花是植物从营养生长向生殖生长的转变过程。拟南芥中存在多条调控开花时间的信号途径如光周期途径、春化途径、赤霉素途径和自动途径等。与草本植物相比,木本植物成花调控研究进展较缓慢。本文综述了木本果树中开花综合基因,即综合不同成花调控途径信号的关键基因,如CO、FLC、SVP、FT、LFY、TFL、AP1、SOC1等的研究进展,以期为进一步探索木本植物成花的分子调控机制提供参考。
Flowering is an important process for plants to transfer from vegetative to reproductive development. Studies on Arabidopsis revealed several pathways were involved in flowering time control, such as photoperiod pathway, vernalization pathway, GA pathway, and autonomous pathway. Compared with herbs, the research progress of flowering regulation in woody plants is slowly and have a big divergence. This review summarizes recent progresses on flowering integrator genes such as CO, FLC, SVP, FT, TFL, AP1, SOC1 and LFY in woody fruit trees, so as to provide reference for further explore about flowering molccttlar mechanism of woody plants.
