摘要: 植物细胞依赖细胞质膜上的受体感知并传递环境信号, 而受体通过与配体特异结合启动一系列下游信号转导途径, 维持植物正常的生命活动及其对外界环境变化的适应。类受体激酶是其中一类重要受体, 通常由胞外结合结构域、跨膜结构域和胞内激酶结构域3部分组成, 是植物适应外界环境变化的重要调节枢纽。FER属于CrRLK1L类受体蛋白激酶家族, 最早被发现在高等植物雌雄配子体识别过程中发挥作用。随后, 众多研究表明, FER在植物生长发育、激素间交互作用、植物与病原菌互作和逆境响应等多种生物学过程中扮演重要角色, 是近年来植物信号通路研究领域的“明星蛋白”。随着植物病理学研究的不断深入, FER在植物与病原菌互作过程中的功能备受关注。该文主要综述FER调节植物与病原菌互作的研究进展, 旨在为进一步解析类受体蛋白激酶在植物细胞响应病原菌侵染过程中的信号转导机制提供参考。

Abstract: Plant cells rely on the receptors on the plasma membrane to sense and transmit environmental signals that mediate by the specific binding of ligands, thus initiating a series of downstream signaling pathways to maintain normal activities of plants and their responses to environmental stimuli. Receptor-like kinases (RLKs) are a group of important receptors composed of extracellular binding domain, transmembrane domain and intracellular kinase domain, which are the important regulatory hubs of plants to respond to environmental stimuli. FERONIA (FER) is a member of CrRLK1L receptor protein kinase family, which was firstly identified to play a role in the recognition between male and female game- tes in higher plants. Subsequently, numerous studies have shown that FER plays an important role in various biological processes, such as plant growth and development, hormonal cross-talk, responses to biotic and abiotic stress. FER has become a “star protein” in the studies of plants signaling transduction in recent years. With the intensification of the studies on plant pathology, the functions of FER in the interaction between plants and pathogens have attracted more attention. In this paper, we summarized the advances in understanding the functions of FER in the plants-pathogen interaction. This review will provide a reference for further understanding the mechanisms of receptor-like protein kinases of plant cells in response to pathogen infection.
