Abstract

Foshou yam () is a tuber food crop in China. It is a rare species of the yam family and known for its high nutritional value. From 2019 to 2021, tuber rot was observed in Foshou yam in Wuxue, Hubei Province, China. Fungal strains were isolated from diseased tubers, and ten representative strains were identified based on microscopical characterization and multi-locus phylogenetic analysis. A total of five different species were identified, including , , , , and . Pathogenicity test revealed that these fungi are the pathogens of tuber rot in Foshou yam. Among them, . exhibited the strongest pathogenicity. To our knowledge, this is the first report of tuber rot in caused by these five species worldwide. This study provides important information for the future management of tuber rot in Foshou yam.

摘要

佛手山药是中国的一种块茎类粮食作物。它是薯蓣科的珍稀物种，以高营养价值著称。2019年至2021年期间，在中国湖北省武穴市的佛手山药中观察到块茎腐烂现象。从患病块茎中分离出真菌菌株，并基于显微镜特征和多位点系统发育分析鉴定出10株代表性菌株。共鉴定出5个不同物种，包括……、……、……、……和……。致病性测试表明，这些真菌是佛手山药块茎腐烂的病原菌。其中，……表现出最强的致病性。据我们所知，这是全球首次报道由这5个物种引起的佛手山药块茎腐烂。本研究为佛手山药块茎腐烂的未来管理提供了重要信息。
