由链格孢菌(Alternaria alternata)引起的柑橘褐斑病(Alternaria brown spot,ABS)是严重为害柑橘的一种真菌病害。在柑橘褐斑病菌中已鉴定出多个信号转导基因,但大多围绕单基因生物学功能的研究,关于信号级联通路主要集中在病原菌解毒活性氧(reactive oxygen species,ROS)方面。研究发现除毒素ACT外,柑橘褐斑病菌对活性氧的高效解毒机制也是其致病所必需的。对柑橘褐斑病菌信号转导基因研究现状进行综述,分析其活性氧解毒相关通路及机制,旨在为进一步研究柑橘褐斑病菌分子致病机制提供参考。
Alternaria brown spot (ABS) caused by Alternaria alternata is a fungal disease that is seriously damaging to citrus. Many signal transduction genes have been identified in Cryptosporidium citri, but most of them focus on the study of single-gene biological functions. The signaling cascades mainly focus on the pathogen detoxification of reactive oxygen species (ROS). The study found that in addition to toxins ACT, Corynebacterium solani efficient reactive detoxification mechanism is also necessary for its pathogenesis. The current research status of brown spot pathogen signal transduction genes were reviewed, and the related pathways and mechanisms of reactive oxygen species detoxification were analyzed in order to provide references for further study on the molecular pathogenesis of brown spot pathogen.
