类受体激酶调控根生长发育的研究进展

Advance in Receptor-like Kinases in Root Growth and Development Control

类受体激酶是一类具有激酶活性的单次跨膜受体,通过接收和传递胞外信号调控细胞的生理反应,参与植物生长发育过程。植物根在生长发育过程中受到大量的外部刺激和内源性发育信号的影响,植物必须通过整合这些信号并转化为细胞反应,才能适应不断变化的环境条件;植物类受体激酶作为细胞膜上的信息监测者,通过与外源和内源信号的通讯调控根的生长发育。该文对近年来国内外有关类受体激酶的结构、分类及其作用机制,特别是植物类受体激酶在根发育信号转导途径中的功能和作用等方面的研究进展进行综述,为进一步揭示植物类受体激酶在根生长发育中的功能及其作用机制提供参考。

Receptor-like kinases (RLKs) are a class of single-transmembrane receptors with kinase activity. They modulate plant growth and development by perceiving and transmitting extracellular signals to regulate cellular physiological responses. Plant roots are suffered by a large amount of external stimuli and endogenous developmental signals during growth and development. Plants must integrate these signals and transform into cellular responses to adapt to changeable environmental conditions. RLKs regulate plant root growth and development by communicating with exogenous and endogenous signals as information monitors on plasma membrane. In this paper, we summarized recent studies on the structure, classification and mechanism of RLKs, and highlighted their function and roles in signal transduction in root development, which provides important information for further revealing the function and mechanism of RLKs in plant root growth and development.
