Abstract

species are important plant pathogens, causing anthracnose in virtually every crop grown throughout the world. However, little is known about the species that infect watermelon. A total of 526 strains were isolated from diseased watermelon samples of eight major watermelon growing provinces in China. Phylogenetic analyses using seven loci (ITS, , , , , , and ) coupled with morphology of 146 representative isolates showed that they belonged to 12 known species of , including , , , , , , , , , , , and and three new species, here described as , , and . was the dominant species. Pathogenicity tests revealed that all isolates of the species described above were pathogenic, with and being the most aggressive to leaves and fruits, respectively. This is the first report of , , , , , , , and on watermelon. These findings shed light on the spp. involved in watermelon anthracnose and provide useful information for implementing effective control of watermelon anthracnose in China.

摘要

该物种是重要的植物病原体，几乎在全球种植的每一种作物上都会引发炭疽病。然而，对于感染西瓜的该物种却知之甚少。从中国八个主要西瓜种植省份的患病西瓜样本中总共分离出526个菌株。利用七个基因座（ITS、、、、、、）进行系统发育分析，并结合146个代表性分离株的形态学特征，结果表明它们属于炭疽菌属的12个已知物种，包括、、、、、、、、、、、，以及三个新物种，在此分别描述为、、。是优势物种。致病性测试表明，上述物种的所有分离株均具有致病性，其中和分别对叶片和果实的侵染性最强。这是、、、、、、、首次在西瓜上的报道。这些发现揭示了涉及西瓜炭疽病的炭疽菌属物种，并为在中国有效防控西瓜炭疽病提供了有用信息。
