摘要
干旱是影响全球生态的重要因子,文章综述了转录调控因子和转录后RNA/蛋白修饰因子两类抗旱相关基因及其在耐旱性遗传改良中的应用。其中,胁迫应答的转录调控因子包括脱水响应因子(DRE)、锌指蛋白(ZFP)、核因子(NF-Y)和WRKY转录因子;转录后RNA/蛋白修饰因子包括蛋白的法尼基化、蛋白磷酸化和蛋白的聚ADP核糖基化作用。这些基因中有的已克隆并通过生物技术手段转入作物中,靶基因的表达提高了作物的抗旱性及产量。
Drought is one of the important factors affecting the global ecological environment. Here we reviewed two types of genes related to drought resistance as well as their cloning and using in genetic engineering for crops. Among them, transcriptional regulation of drought stress responses including transcriptional factors responsive to dehydration, Zinc Finger Protein, Nuclear Factor and WRKY. Post-translation protein modifications in drought response consisted of protein farnesylation, ptotein phosphorylation and protein poly (ADP-ribosyl)ation. Some of the genes mentioned above had been cloned and embedded in crops by genetic engineering, the expression of the target gene had improved the drought tolerance and yield of crop.
