植物响应淹水胁迫的研究进展

淹水胁迫是影响植物分布与生长发育的重要因素,植物耐涝性研究是提高作物耐涝性以应对日益严峻的极端气候及规模化生产管理的关键。为了合理开展植物耐涝性研究,深入挖掘不同植物响应淹水胁迫的调控机理,本文归纳了淹水胁迫对植物生长发育的影响,总结了植物响应淹水胁迫的调节机制,并详细分析了淹水胁迫对植物表型性状、生物量、光合作用、活性氧离子积累、糖含量和生物膜的影响,以及乙烯信号分子、活性氧清除机制、渗透调节、形态调节、分子和代谢调控在植物响应淹水胁迫中的调节机制。最后,通过总结,提出了合理开发外源调节物质提高作物耐涝性值得进一步的深入研究。

Plant Response to Waterlogging Stress: Research Progress

Waterlogging stress is an important factor that affects the distribution, growth and development of plants. The research on plant waterlogging tolerance is critical to improving plant tolerance in order to cope with the increasingly severe extreme weather and the large-scale production management. In order to carry out researches on plant waterlogging tolerance and explore the regulation mechanism of different plants in response to waterlogging stress, we summarized the effects of waterlogging stress on plant growth, the regulation mechanism of plant in response to waterlogging stress, and analyzed the effects of waterlogging stress on plant phenotypic traits, biomass, photosynthesis, reactive oxygen species accumulation, sugar content as well as biological membrane in detail. In addition, the regulation mechanism of ethylene signal molecule, reactive oxygen species scavenging mechanism, osmotic regulation, morphological regulation, molecular and metabolic regulation of plant in response to waterlogging stress were also analyzed. Finally, it is proposed that further in-depth study should be focus on the development of exogenous regulatory substances to improve plant waterlogging tolerance.
