辣椒应答冷信号转导机制研究进展

Research progress of cold signal transduction mechanisms in pepper

辣椒原产中南美洲热带地区,为喜温性蔬菜作物。冷害是辣椒生产中的主要逆境因子,严重影响辣椒的生长发育。遭受冷害胁迫时,包括辣椒在内的众多植物通过多个信号转导途径调节耐冷相关基因的表达,提高植物的耐冷性。本文从冷信号感知、冷信号转导途径中关键转录因子、耐冷基因表达等方面,综述了辣椒应答冷信号的研究进展,从而为辣椒耐冷分子机制研究提供参考。

Pepper(Capsicum spp.),which originates from tropical region of Central and South America,is a thermophilic vegetable crop.Cold stress is one of the main environmental limitations in pepper production,which seviously affects plant growth and development.Under chilling stress,many plants,including pepper,regulate the expression of genes related to cold tolerance various signal transduction pathways to improve cold tolerance.In this paper,the research progress of response to cold stress in pepper was reviewed from the aspects of cold signal sensing,the key transcription factors and expression of coldtolerance genes in cold-related signal transduction pathways.This paper provides reference for the study of molecular mechanism of cold tolerance in pepper.
