摘　要：

生长素作为最早被人们发现的植物激素, 在植物生长发育的各个环节都起着重要作用。然而, 因为无法自由选择生活环境, 植物个体往往在生长过程中不可避免地遇到各种生物的和非生物的胁迫, 加之全球气候的恶化, 非生物胁迫对植物生长的影响越来越显著。了解植物激素, 尤其是生长素在植物体应对非生物胁迫时的作用有助于人们更好地找到应对胁迫, 保障农作物和经济作物产量的措施。非生物胁迫中, 冷胁迫是限制植物生长发育和作物产量的一个主要胁迫因子, 本文综述了生长素在冷胁迫下植物应答反应中的研究进展, 同时对以生长素为中心的植物激素网络调控与胁迫的关系也作了阐述。

Abstract:

As the first discovered plant hormone, auxin plays important roles in plant growth and development. It will help to cope with stress and to ensure the yield of crops and economic crops, if we could understand the function of auxin in response to biotic and abiotic stresses. Among various abiotic stresses, cold stress is a main factor which limited plant growth and development. Here, the research progress of auxin as a regulator of cold stress response is reviewed. At the same time, the relationship between stress response and the complex regulatory network of hormones which centered on auxin is also discussed.

Key words: auxin; regulatory network of hormones; cold stress
