植物光系统II(PSII)应答非生物胁迫机理研究进展
Research Progress in the Mechanism of Plant Photosystem II(PSII)Responsing to Abiotic Stress
摘要
Abstract
Plant growth process is influenced by a series of abiotic stresses represented by environmental factors(temperature,drought,salinity,and heavy metals,etc.),which hinder the photosynthetic process mainly characterized by substance conversion and energy metabolism.Photosystem II(PSII)is a multi-subunit pigment-protein complex located on the thylakoid membrane,which is particularly important for plant growth and development by capturing light energy to complete the photolysis of water and plastoquinone reduction.Generally,abiotic stress may inhibit the activity of PSII,affect its structure,and hinder electron transport and energy conversion.As the most vulnerable part of photosynthesis,PSII has attracted much attention in recent years due to its relationship with environmental factors.Based on this,this article summarized the physiological responses of plant PSII under major abiotic stresses such as temperature,drought,salt and heavy metals,and reviewed the structure and function of PSII,electron transfer process,photoinhibition and photoprotection based on chlorophyll fluorescence technology.It also provides a theoretical basis for further research on the physiological and molecular mechanisms of plant PSII response to abiotic stress.关键词
