摘要:

盐胁迫是限制植物生长和产量的重要环境因子之一。经过长期的进化,植物已形成了一套响应盐胁迫的调控机制。转录组学可以从植物mRNA整体转录水平揭示植物响应盐胁迫的调控机制,对研究植物抗盐、耐盐具有重要意义。本文针对转录组学在植物响应盐胁迫调控机制中的研究,简述了植物体内的信号传导、渗透调节、内源激素合成、光合作用、活性氧清除、次生代谢与细胞壁合成、转录因子等有关的差异表达基因,从转录水平上分析了植物的耐盐机制,为今后植物抗逆分子研究提供参考。

Abstract:

Salt stress is one of the important environmental factors that limit plant growth and yield. After long-term evolution, plants have formed a set of regulatory mechanisms that response to salt stress. Transcriptomics can reveal the regulation mechanism of plants in response to salt stress from the overall transcription level of plant mRNA, which is of great significance for the study of plant salt resistance and salt tolerance. Aiming at the transcriptome study in revealing the mechanism of plant response to salt stress control in the research, this paper expounded on differentially expressed genes of signal transduction, osmoregulation, endogenous hormone synthesis, photosynthesis, reactive oxygen removal, secondary metabolism, cell wall synthesis and transcription factors. The mechanism of salt tolerance in plants was analyzed at the transcriptional level, which could provide a reference for molecular research of plant stress tolerance in the future.

Key words: salt stress, transcriptome, differenially expressed gene
