摘要: 离子型谷氨酸受体(iGLuR)是哺乳动物中一类由L-氨基酸(如谷氨酸、甘氨酸)等配体门控的阳离子通道, 具有调节兴奋性神经信号传递和引导神经元发育等分子功能。1998年研究者在拟南芥(Arabidopsis thaliana)中发现了20个与iGLuRs同源的序列(即AtGLRs), 它们的功能涉及植物光信号传递、根尖分生细胞活性、花粉管生长、胞质Ca2+流以及应答多种生物和非生物环境胁迫等。该文从谷氨酸受体(GLR)的结构特征、离子通道激活与配体的关系、表达模式及可能的生物学功能等方面, 综述了近十几年来关于植物GLR和氨基酸信号的研究成果, 旨在为相关领域的同行提供有益的参考。

Abstract: In mammals, ionotropic glutamate receptors (iGLuR) are amino acids (e.g. glutamate and glycine) -gated cation channels, and exhibit molecular functions in the regulation of excitatory neurotransmission as well as in directing neuron growth. Since 1998 twenty genes homologous to iGLuR have been identified in Arabidopsis genome (termed AtGLRs), with reported functions involved in many biological processes including light signaling, root-tip meristematic cell activity, pollen tube growth, cytosolic calcium ion flux and response to varied biotic and abiotic stresses. This paper comprehensively summarizes research achievements or advances in terms of plant glutamate receptors and amino acid (e.g. glutamate) signaling in the past more than ten years, with major issues focusing on e.g. the protein structure of GLRs, a relationship between activation of ion channels and their ligands, their gene expression patterns as well as possible biological roles in plants, thus hopefully providing valuable information for researchers related to this field.
