2019年5月,在湖南长沙地区富贵草上发生了一种不明原因的叶部病害,对其进行病原菌分离、形态学鉴定和科赫氏法则验证,并通过对核糖体转录间区r DNA（ITS）、肌动蛋白基因（ACT）、几丁质合成酶1基因（CHS1）和甘油醛–3–磷酸脱氢酶基因（GAPDH）序列的系统进化树分析,对病原菌进行分子鉴定,确定病原菌为冬麦刺盘孢（Colletotrichum liriopes）。

In this study,we isolated and identified the pathogen of a unknown leaf spot disease occurred on Pachysandra terminalis(P.terminalis)plants,in May 2019 in Changsha,Hunan Province of China.Based on morphological characteristics,pathogenicity test,and molecular identification which was conducted by constructing the phylogenetic tree using combined gene sequences of internal transcribed spacer(ITS)rDNA,actin(ACT),chitin synthase 1(CHS1)and glyceraldehyde-3-phosphate dehydrogenase(GAPDH).Based on the above results,we can conclude that the le...
