【摘要】：植物盐害的阴离子毒害主要由Cl~-造成,盐逆境下植物体内Cl~-吸收、运输及其调控的分子机制已成为植物耐盐性研究不可忽视的重要方面,但有关Cl~-毒害问题相对Na~+毒害和适应的研究在过去较少受到关注。Cl~-通道(chloride channels,CLCs)是一类广泛分布于原核和真核生物细胞膜(主要是内膜系统),以介导Cl~-为代表的阴离子运输的重要转运蛋白家族。本文对目前已报道的包括拟南芥、大豆、水稻等多种植物的CLC同源基因及其编码蛋白进行了系统的生物信息学分析,并对植物CLC同源基因参与耐氯(盐)功能解析方面的研究进展进行了归纳,为今后进一步发掘和利用植物耐氯(盐)基因,全面揭示植物耐盐性的分子机制和最终寻求提高大豆、水稻等作物耐氯(盐)性的分子育种途径,指明可借鉴的研究方向。
[Abstract]:The anion toxicity of plant salt damage is mainly caused by ClO-, and the molecular mechanism of Cl ~ + absorption, transport and regulation in plants under salt stress has become an important aspect in the study of plant salt tolerance. In the past, however, less attention has been paid to the study of Cl-toxicity in relation to Na- toxicity and adaptation. Cl-channel chloride channels (CLCs) are a class of prokaryotic and eukaryote cell membranes (mainly intimal systems, which are represented by mediating Cln-). A family of important transporter proteins for seed transport. In this review, Arabidopsis, including Arabidopsis thaliana, has been reported. The CLC homologous genes and their encoded proteins of soybean, rice and other plants were systematically analyzed by bioinformatics, and the research progress of plant CLC homologous genes involved in chlorine (salt) tolerance function analysis was summarized. In order to further explore and utilize chlorine (salt) tolerance genes in plants, fully reveal the molecular mechanism of salt tolerance in plants and ultimately seek molecular breeding ways to improve chlorine tolerance in soybean and rice crops, the research direction that can be used for reference is pointed out.
