Banana fruit rot is a common postharvest disease of the banana fruit. The appearance of rot symptoms on the surface of the fruits reduces the quality and marketability of banana. From rot lesions on banana fruits, three isolates were isolated. Based on morphological characteristics and sequences of Internal Transcribed Spacer, β-tubulin and calmodulin, the isolates were identified as . Pathogenicity tests of the isolates, conducted using mycelial plugs with wounded and unwounded treatments, showed as the pathogen of banana fruit rot. Rot symptoms were highly severe on wounded banana fruits compared to unwounded fruits, and therefore, wounded banana fruits are more susceptible to infection. To the best of our knowledge, this is the first report of as a causal pathogen of banana fruit rot. This study indicated is one of postharvest rot pathogens of banana.
香蕉果实腐烂是香蕉果实常见的采后病害。果实表面出现腐烂症状会降低香蕉的品质和市场适销性。从香蕉果实的腐烂病斑中分离出三株菌株。基于形态特征以及内转录间隔区、β-微管蛋白和钙调蛋白的序列，这些菌株被鉴定为 。使用带有创伤和未创伤处理的菌丝块对这些菌株进行致病性测试，结果表明 是香蕉果实腐烂的病原菌。与未创伤的果实相比，创伤的香蕉果实上的腐烂症状更为严重，因此，创伤的香蕉果实更容易受到 感染。据我们所知，这是关于 作为香蕉果实腐烂致病病原菌的首次报道。这项研究表明 是香蕉采后腐烂病原菌之一。
