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.
