| 摘 要： | 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。

| Abstract: | Citrus Alternaria brown spot（ABS）caused by the tangerine pathotype of Alternaria alternata is a fungal disease，which has posed a threat to the citrus industy. Considerable advances have focused on the signal transduction genes in the tangerine pathotype of A. alternata，but most are involved in biological functions of a single gene. Signaling pathways mediating ROS detoxification have been elucidated. ACT toxin produced by the tangerine pathotype of A. alternata is responsible for the infection of citrus. Studies have shown that the ability to mitigate the toxicity of ROS is also required for pathogenesis. This paper summarizes the latest knowledge of signal transduction genes，signaling pathways and mechanism associated with ROS detoxification in the tangerine pathotype of A. alternata，aimed at providing some theoretical reference for the molecular pathogenesis on the tangerine pathotype of A. alternata. |
