spp. are well known to be plant pathogens, endophytes, or saprophytes on a wide range of economically significant crops, ornamental plants, and forest trees. In the present study, we aimed to investigate the diversity of species, which cause kiwifruit soft rot in Guizhou Province. Five strains of fungi were isolated from kiwifruit infected with soft rot in Guizhou province. These strains were identified using morphological and multilocus sequences analysis of the rDNA internal transcribed spacer region (ITS), calmodulin (), histone H3 (), translation elongation factor 1-alpha (), and β-tubulin (). The results confirmed two new species - and This study identifies two new soft-rot pathogens of kiwifruit and provides a reference for future disease-management studies.
已知某些物种是多种具有重要经济意义的农作物、观赏植物和林木上的植物病原体、内生菌或腐生菌。在本研究中,我们旨在调查贵州省导致猕猴桃软腐病的物种多样性。从贵州省感染软腐病的猕猴桃中分离出五株真菌菌株。使用核糖体DNA内部转录间隔区(ITS)、钙调蛋白()、组蛋白H3()、翻译延伸因子1-α()和β-微管蛋白()的形态学和多位点序列分析对这些菌株进行鉴定。结果证实了两个新物种—— 和 。本研究鉴定出两种猕猴桃软腐病的新病原体,并为未来的病害管理研究提供了参考。
