转录组学和代谢组学在植物应答温度胁迫中的研究进展

Research Progress of Transcriptomics and Metabolomics in Plant Response to Temperature Stress

摘要:

极端温度是制约植物正常生长发育的重要因素。在温度胁迫下，植物会通过重新配置转录调控与代谢网络来保证生存和持续生长。近年来，随着测序技术和质谱技术等生物技术的发展，转录组学和代谢组学是继基因组学和蛋白质组学之后发展起来的新兴学科，有助于鉴定非生物胁迫下植物内的代谢产物和调控基因。本文主要分析转录组学和代谢组学的技术特点及优缺点，就近年来国内外关于转录组学和代谢组学在植物应答温度胁迫(高温胁迫和低温胁迫)两方面的研究进展进行综述，同时针对目前所面临的问题进行展望，有助于加快解析植物响应温度胁迫的机理，为未来培育抗逆新品种提供新思路。

Abstract:

Extreme temperature is an important factor to limit plant growth and development. Under temperature stress, plants mainly reconfigure transcriptional regulatory and metabolic networks to maintain life and keep growing. In recent years, with the development of biotechnology such as sequencing technology and mass spectrometry technology, transcriptomics and metabolomics are new subjects that have developed after genomics and proteomics, helping to identify metabolites and modulate genes in plants under abiotic stress. The characteristics, advantages, and disadvantages of transcriptomics and metabolomics technologies were analyzed. The research progress of plant transcriptomics and metabolomics under temperature stress(high-temperature stress and low-temperature stress) were reviewed in domestic and international. Moreover, in view of the current problems, the future was prospected, which will accelerate the analysis of the mechanism of plant response to temperature stresses and provide new ideas for the cultivation of stress resistant varieties in the future.
