| 摘 要： | 热激蛋白90(HSP90,heat shock protein 90)广泛介导了胁迫信号的传递,在控制人体细胞正常生长和促进肿瘤细胞发育中起着重要作用。目前,HSP90已成为细胞免疫、信号转导以及抗肿瘤研究的前沿课题。但植物HSP90的生理功能研究起步较晚,最近的研究发现HSP90在植物发育、胁迫环境的应答以及抗病性中起着重要作用。本文从分子生物学角度,系统综述了植物HSP90分子作用机理研究的最新进展,以及在改良植物抗性上的应用,以期为通过基因工程方法改良作物抗性提供参考。

| Abstract: | Heat shock protein 90 (HSP90) widely mediated stress signal transduction, and plays an important role in the control of normal growth of human cells and in the promoting tumor cell development. At present, HSP90 has become forefront projects of cellular immunity, signal transduction and anti-cancer investigation. The physiological function of HSP90 start later in plant than in animal and fungi. Recent researches revealed that plant HSP90 plays an important role in development, environmental stress response and disease resistance. This paper discussed the molecular functions of HSP90, and systematically reviews latest progresses on molecular mechanism of plant HSP90 as well as improvement of plant resistance to facalitate broaden work. |
