【摘要】 土壤盐渍化是危害世界农业的一个重要的环境因素。土壤中高浓度的盐分会使离子失衡、氧化伤害、水分亏缺、营养缺乏,并导致生物大分子被破坏、生长迟缓、甚至植株死亡。关于植物耐盐性机理研究,以及耐盐作物品种的选育已经成为近年来植物研究领域和生物技术领域的研究热点。分子生物学技术的不断发展,尤其是后基因组时代蛋白质组技术的不断进步,为植物的抗性研究提供了新思路,从而也极大促进了植物耐盐性分子机制的研究。本文就这方面的研究进展进行了简要的综述。更多还原

【Abstract】 Soil salinity-alkalinity is one of the most important factors restricting agriculture worldwide. High concentration of salt in soil causes ion imbalance, oxidative damage, water deficit and nutrient deficiency, which lead to molecular damage, growth retarded, and even death of plant. Studies on salt tolerance mechanisms of plant and salt tolerance crops breeding have become to the focus issue within agricultural and biotechnological regions in recent years. The development of molecular biotechniques, especially the improving of proteomic techniques in post genome era gives new insight into salinity-alkalinity stress response in plant,and accelerates the understanding of the molecular mechanism of salt tolerance. This review summarized the achievements and the developments of plant salt tolerance research on molecular biology, in particular, on proteomics recently.更多还原
