近几年来,关于寄主专化性毒素(Host-Specific Toxin,HST)的作用机制及分子生物学方面的研究有了新进展;在14种寄主专化性毒素中,以Alternaria属的病原菌产生的专化性毒素的研究更为深入。非寄主专化性毒素(Non-Host-Specific Toxin,NHST)的研究着重在毒素产生的条件、生物活性测定、抗性鉴定以及检测被感染植物体的毒素含量等。本文综述了一些能产生专化性毒素和非专化性毒素的植物病原真菌,有链格孢(Alternaria)、镰孢(Fusarium)、尾孢(Cercospora)、轮枝孢(Verticillium)、梨孢(Pyricularia)、疫霉(Phytophthora)、长蠕孢(Helminthosporium)、黑团孢(Periconia)和核盘菌(sclerotinia)等属的病原菌。从所发表的文献表明真菌毒素在植物病害发展中起着重要作用。
In recent years, new progress has been made in the research on the mechanism of action and molecular biology of host-specific Toxin (HST). Of 14 host-specific toxins, which are produced by pathogens of the genus Alternaria Specialized toxins more in-depth study. Non-Host-Specific Toxin (NHST) research focuses on the conditions of toxin production, bioactivity determination, resistance identification, and detection of toxin content in infected plants. This review summarizes plant pathogenic fungi that produce both specific and non-specific toxins, including Alternaria, Fusarium, Cercospora, Verticillium, Pyricularia, Phytophthora, Helminthosporium, Periconia, and Sclerotinia. From the published literature, mycotoxins play an important role in the development of plant diseases.
