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

  • 摘要: 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。

     

    Abstract: 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.
