植物受病原物诱导启动子是一类能对病原物的侵染作出响应的启动子,其活性主要局限于被侵染之时及被侵染的位点。植物受病原物诱导启动子的这一特性赋予其在抗病基因工程中潜在的应用价值。相比植物庞大的启动子组,已发现的植物受病原物诱导启动子仍是少数,关于其作用机制的研究仍有待加强和深入,而其调控的基因与植物抗病性关系还需要引起足够的重视。作者在对植物受病原物诱导启动子进行归类的基础上,重点关注了病原物诱导启动子调控基因的编码产物与植物抗病性的关系,对植物受病原物诱导启动子的顺式调控元件作了简要分析,并对该领域的发展动向进行了讨论。
Plants are pathogen-inducible promoters, a class of promoters that respond to the infection of pathogens, whose activity is mainly restricted to the site of infection and to the site of infection. This feature of the plant pathogen-inducible promoter gives it potential value in resistance gene engineering. Compared with the large plant promoter group, the discovered plants are still a few promoters induced by pathogenic agents. The research on their mechanism of action needs to be further strengthened and further, and the relationship between the regulated genes and plant disease resistance needs to be enough The importance of. Based on the classification of plant-induced promoters by pathogens, the author focuses on the relationship between the coding products of the pathogen-inducible promoter regulatory genes and the disease resistance of plants and the cis-regulation of plant-induced promoters The components are briefly analyzed and the development of the field is discussed.
