摘要
干旱、涝渍、极端温度以及病虫害等多种逆境胁迫严重影响辣椒的生长,导致辣椒发育不良而减产.启动子包含重要的顺式作用元件,对目的基因的表达调控有重要作用,尤其是植物诱导型启动子,在胁迫条件下会激发抗逆调控机制与激活目的基因表达,改变植物代谢组分和生理生化反应,增强植物抗逆性.主要对辣椒应答干旱、高温、低温、盐等非生物和生物胁迫诱导型启动子的种类、功能以及与反式作用因子的互作进行综述,以期为进一步研究辣椒基因诱导型启动子提供一定的理论依据和抗逆品种改良提供参考.
Abstract
Drought,waterlogging,extreme temperature,pests and diseases seriously affect the growth of pepper,leading to poor development and reduced yield.Promoters contain important cis-acting elements and play crucial roles in regulat-ing the expression of target genes.Plant inducible promoters can stimulate stress resistance regulatory mechanisms and ac-tivate the expression of target genes under stress conditions,which alter plant metabolic components and physiologi-cal-biochemical reactions,and enhance plant stress resistance.In this paper,the authors mainly review the types,func-tions,and interactions with trans-acting factors of inducible promoters in response to abiotic and biotic stresses,such as drought,high temperature,low temperature,salt in pepper,in order to provide a theoretical basis for further research on in-ducible promoters of pepper genes and stress-tolerant cultivar improvement.
