miR396-GRF模块参与植物逆境胁迫响应的研究进展

Research progress on miR396-GRF module regulating plant stress response

miR396-GRF模块是一类新型高效的植物生长发育调控模块。该模块中miR396通过负调控生长调节因子GRF,影响植物生长发育过程中的信号传导通路,并广泛参与植物对干旱、盐害、温度、UV-B等非生物胁迫,以及胞囊线虫和病原菌等造成的生物胁迫的响应过程。本文综述了miR396-GRF模块的调控网络和其参与植物抗逆响应的作用机理,并探讨了相关研究动态及存在的问题,旨在为进一步推动GRF相关研究提供理论参考。

The miR396-GRF module is a novel and efficient plant growth and development regulatory module.In this module,miR396 negatively regulates growth-regulating factor(GRF),affects the signal transduction pathway in the process of plant growth and development,and participates in the response of plants to abiotic stress(e.g.,drought,salt damage,temperature,and UV-B radiation)and biological stress(e.g.,cyst nematodes and pathogens).In this review,we discuss the regulatory network of the miR396-GRF module and the response mechanism involved in plant stress resistance,and further discuss related research trends and existing problems to provide a theoretical reference for future research on GRF.
