摘要:

设施栽培冬春生产中的低温逆境严重影响番茄等喜温作物的光合作用,而不适宜的光强、光周期、光质等光环境加剧了作物的低温光抑制,导致产量降低和品质变劣。因此,解析植物响应光温逆境的生理分子机制对冬春季节生产中作物抗逆性调控不可或缺。近年来,植物响应光温逆境的分子机制逐渐清晰,然而光温信号整合因子及其功能还有待进一步挖掘。基于此,对番茄响应光温逆境的生理分子机制进行了综述,重点讨论了光及其信号对植物低温抗性的影响,并分析了此领域研究中存在的问题及今后研究的方向,以期为减轻番茄的逆境危害、提高产量和品质等提供参考,也为深入探索新的光温互作因子及其功能奠定基础。

Abstract:

The cold stress during the greenhouse production in winter and spring has seriously affected the photosynthesis of thermophilic crops such as tomato. Importantly,the inappropriate light intensity,photoperiod,light quality and other light environments have intensified the cold-induced photoinhibition in crop,resulting in the decline of yield and quality. Therefore,it is necessary to analyze the physiological and molecular mechanism of plant response to light and temperature stresses for the regulation of crop stress tolerance during winter and spring. Recently,the molecular mechanism of plant response to light and temperature stresses has been gradually clarified. However,the integration factors of light and temperature signaling pathways and their functions still need to be further explored. Here,we review some recent advances in our understanding of the physiological and molecular mechanisms of tomato response to light and temperature stresses,with an emphasis on the effects of light and its signals on plant cold tolerance. In addition,the main problems in current researches were pointed out and the key points in future studies were also proposed. It is expected to provide a reference for alleviating the stress effects of tomatoes,improving yield and quality,and laying a foundation for in-depth exploration of new light-temperature integration factors and their functions.

Key words: tomato, light, temperature, light signal, stress
