胁迫诱导植物体细胞胚发生中相关基因及蛋白的研究进展

摘要

Somatic embryogenesis (SE) is a complicated developmental process and a unique model system to investigate the physiological,biochemical,and molecular biological events occurring during plant embryo development. Stresses are very important factors that have been increasingly recognized in the induction of SE. Plant growth regulators such as 2,4-dichlorophenoxyacetic acid (2,4-D),ABA and so on are known as stress-related substances for acquisition of embryogenic competence by plant cells. Some stress-related genes and proteins associated with SE have been identified and researched from both the proteome and transcriptome levels. This review focuses on stress-related genes and proteins in the induction of SE.%植物体细胞胚发生是一个复杂的发育过程,体细胞胚发生已成为研究植物胚胎发育过程中生理、生化、分子生物学等方面分子机理的模式系统.胁迫被认为是对体细胞胚的诱导有重要作用的因素.植物生长调节物质如2,4-D、ABA等目前认为是与胚性能力获得有关的胁迫物质.在蛋白和转录水平上对基因表达的分析中已鉴定出一些与体细胞胚发生相关的基因和蛋白.该文主要对近年来国内外有关胁迫诱导体细胞胚发生的相关基因及蛋白的研究进展进行综述.
