摘要
对近年来牧草和草坪草耐热性方面的研究进行了综述,包括高温对牧草和草坪草生理生化指标及形态结构的影响;高温胁迫下牧草和草坪草对高温的响应,包括细胞膜热稳定性、水分状况、碳氮素代谢、光合及呼吸作用、热激蛋白诱导、内源激素等基本耐热影响因素的变化情况,旨在为耐热品种筛选奠定基础。对抗热基因的差异表达、分离克隆,热胁迫下信号转导、热激蛋白及蛋白差异表达情况方面的研究进展做了综述。并对今后此领域的研究方向和应用前景进行了讨论。
The recent research work on heat tolerance of forage and turfgrass were reviewed in this paper in terms of the stability of cell membranes,self induction of heat shock proteins,water,nitrogen and endogenous hormones.The influence of hot stress on photosynthesis and respiration were discussed.The work on physiological responses of sugar metabolism,identification and characterization of genes associated with heat tolerance,differentially expressed protein under hot stress and heat stress-induced signal transduction was also discussed.
