摘　　要：盐碱是影响作物产量的主要非生物胁迫之一。pH恒稳态是植物正常生长和发育的必要条件,也是植物细胞生命过程中的重要信号,在许多信号转导中起重要的调控作用。但植物对高pH逆境响应和信号转导的分子机理研究尚未得到充分重视。本文对盐碱地高pH因素对植物生长发育的影响及相关分子生物学研究进展进行了综述,并提出了今后植物在盐碱复杂胁迫条件下遗传机理的研究策略。Saline-alkaline stress is one of the major abiotic stresses that influence the yield of crops, pH homeostasis is critical to plant growth and development, pH also mediates many signal transduction pathways in plant response to various internal and external stimuli. However, molecular genetics of pH signal transduction and plant response to high pH is largely unknown. In this paper, the authors summarize the progress in physiology and molecular biology of plant in response to high pH and regulation of pH homeostasis. The authors also provide insights into future research on elucidation of genetic basis of pH signal transduction and tolerance of plant to high pH.
