is a native perennial plant used in traditional Mexican medicine. In June 2022, leaf blight symptoms were observed in a wild population of plants. Disease incidence was 80% and disease intensity reached up to 5% of the leaf area. Currently, there are no reports of pathogens causing leaf blight in this plant; therefore, this work aimed to identify the fungi responsible for the disease. The fungi recovered from the diseased tissue were characterized by means of pathogenicity tests and cultural, morphological, and molecular characterization. The information obtained revealed that and are the pathogens responsible for the disease. This is the first report implicating species of in causing leaf blight of in Mexico, as well as the first report of also in Mexico. These pathogens may threaten the in situ conservation of native populations and limit their in vitro propagation. Future research lines should focus on determining the effect of these pathogens on metabolite production.
是一种墨西哥本土多年生植物，用于传统医学。2022年6月，在该植物的野生种群中观察到叶枯病症状。发病率为80%，病害严重程度达到叶面积的5%。目前，尚无关于该植物叶枯病病原菌的报道；因此，本研究旨在鉴定引起该病的真菌。从患病组织中分离出的真菌通过致病性测试、培养、形态学和分子特征进行鉴定。所获得的信息表明，[具体真菌名称1]和[具体真菌名称2]是引起该病的病原菌。这是墨西哥首次报道[具体真菌名称1]和[具体真菌名称2]引起该植物叶枯病，也是墨西哥首次报道[具体真菌名称2]。这些病原菌可能威胁该植物野生种群的原地保护，并限制其离体繁殖。未来的研究方向应集中在确定这些病原菌对代谢产物产生的影响。
