CRF转录因子调控植物生长发育的研究进展

Advances in the regulation of plant growth and development by cytokinin response factor

细胞分裂素应答因子(cytokinin response factors,CRFs)是植物特有的转录因子,属于AP2/ERF家族的亚组成员。CRFs在细胞分裂素双元组分信号通路分支中发挥作用。最近研究表明CRFs参与植物胚胎形成、种子发育、根系生长以及叶片衰老等过程,在低温、氧化、盐等胁迫响应中起重要的调控作用。本文简要介绍了CRFs转录因子特征及其在细胞分裂素信号途径的作用,重点阐述CRFs调控植物生长发育、胁迫响应等方面的研究进展。

Cytokinin response factors(CRFs)are plant specific transcription factors,belonging to the AP2/ERF family of subgroup members.CRFs plays a role in the branch of cytokinin binomial signaling pathway.Recent studies have shown that CRFs is involved in plant embryo formation,seed development,root growth and leaf senescence,and plays an important regulatory role in response to stress such as low temperature,oxidation and salt.This paper briefly introduces the characteristics of CRFs transcription factors and their role in cytokinin signaling pathway,and focuses on the research progress in the regulation of plant growth and development and stress response by CRFs.
