植物耐涝分子机理研究进展

Research Progress on Molecular Mechanism of Waterlogging Tolerance in Plants

涝害严重影响植物的生长发育和产量形成,引起植物光合作用、不定根发生等地上和地下部形态特性发生变化,乙烯和脱落酸含量也会发生改变,糖代谢失衡,并诱导碳水化合物代谢调节相关基因的表达。植物AP2/ERF类转录因子基因SUB1、HRE和植物类钙调神经磷酸酶B亚基互作蛋白激酶基因CIPK是值得关注的与植物耐涝性调控相关的新基因。今后我们应重视挖掘控制植物耐涝性状的关键基因,开展植物耐涝性的分子遗传改良与种质创新,为农业产业的健康发展奠定基础。

Waterlogging seriously affect plant growth, yield formation, cause changes in aboveground and belowground morphological characteristics of plant, such as photosynthesis, adventitious root formation etc.Waterlogging also cause changes in content of ethylene and abscisic acid, glucose metabolism disorder, and induce expression of genes related to regulation of carbohydrate metabolism. SUB1（Submergence 1）,（Hypoxia responsive ERF genes） and CIPK（calcineurin B-like-interacting protein kinase） were the new genes which were worth to be concerned with the regulation and control of plant tolerance to waterlogging. In the future, we should pay attention to explore the key genes that control the waterlogging tolerance of plants, carry out the molecular genetic improvement and germplasm innovation, and lay the foundation for the healthy development of the agricultural industry.
