is regarded as one of the 10 most important genera of plant pathogens in the world. It causes diseases in a wide range of economically important plants, including peaches. China is the largest producer of peaches in the world but little is known about the spp. affecting the crop. In 2017 and 2018, a total of 286 isolates were isolated from symptomatic fruit and leaves in 11 peach production provinces of China. Based on multilocus phylogenetic analyses (ITS, , , , , , and ) and morphological characterization, the isolates were identified to be , , and of the species complex, and of the species complex, of the species complex, and one newly identified species, sp. nov. This study is the first report of and in peaches, and the first report of , , , and in peaches in China. is the most prevalent species of in peaches in China, which may be the result of fungicide selection. Pathogenicity tests revealed that all species found in this study were pathogenic on both the leaves and fruit of peaches, except for , which only infected the leaves. The present study substantially improves our understanding of the causal agents of anthracnose on peaches in China.
被认为是世界上10种最重要的植物病原体属之一。它会在包括桃子在内的多种具有重要经济价值的植物上引发疾病。中国是世界上最大的桃子生产国,但对于影响桃子作物的[病原体名称]种类却知之甚少。2017年和2018年,在中国11个桃子生产省份中,从有症状的果实和叶片中共分离出286株[病原体名称]分离株。基于多位点系统发育分析(ITS、[其他基因位点名称1]、[其他基因位点名称2]、[其他基因位点名称3]、[其他基因位点名称4]、[其他基因位点名称5]和[其他基因位点名称6])以及形态学特征,这些分离株被鉴定为[物种复合群名称1]的[物种名称1]、[物种名称2]和[物种名称3],[物种复合群名称2]的[物种名称4]和[物种名称5],[物种复合群名称3]的[物种名称6],以及一个新鉴定的物种,[新物种名称]。本研究是[物种名称4]和[物种名称5]在桃子上的首次报道,也是[物种名称1]、[物种名称2]、[物种名称3]和[物种名称6]在中国桃子上的首次报道。[物种名称1]是中国桃子中[病原体名称]最普遍的物种,这可能是杀菌剂选择的结果。致病性测试表明,本研究中发现的所有物种对桃子的叶片和果实都具有致病性,但[物种名称6]除外,它仅感染叶片。本研究极大地增进了我们对中国桃子炭疽病病原体的了解。
