摘要
土壤盐害是一个全球性的生态问题,对生态环境和农业生产带来了巨大的负面影响。研究发现,植物磷脂酶D(Phospholipase D,PLD)是磷脂代谢和应答非生物胁迫的重要酶类;PLD具有不同的结构、生化和调节特性,产生信号分子磷脂酸(Phosphatidic acid,PA)并参与多种胁迫反应。总结了PLD及其产物PA调控植物耐盐的相关报道,探讨其感受、应答盐信号的分子机制,为研究植物应答高盐胁迫和农作物分子遗传改良提供相关参考。
Soil salinity is a global ecological problem,which has a great negative impact on ecological environment and agricultural production. Researches showed that Phospholipase D（PLD）was a key enzyme in catalyzing lipids and response to abiotic stresses. PLDs contained diverse structures,distinguishable biochemical and regulatory properties,which produced phosphatidic acid（PA）and participated in plant response to various stresses. This review summarized the current advances in regulating plant salt tolerance,and discussed the putative molecular mechanisms of PLD in sensing and response to salt stress,which might benefit the study of plant salt resistance and crop genetic enhancement.
