| 摘 要： | 从福建多地采集了55份感染叶斑病的枫香植物病样,包含叶片、叶柄、枝条和树皮。通过分离纯化得到了12个类拟盘多毛孢属真菌菌株,综合形态特征以及3个基因(ITS、β-tubulin和tef1)的分子系统发育分析结果,分别鉴定为Neopestalotiopsis cocoes、N. chrysea、Pestalotiopsis neglecta和P. neolitseae,均为枫香上首次报道,其中N. cocoes在国内首次被发现。通过柯赫氏法则验证,发现N. cocoes能够侵染叶片、叶柄和枝条,N. chrysea能侵染叶片和枝条,P. neglecta能侵染叶柄和枝条,而P. neolitseae不能侵染枫香植物组织。

| Abstract: | Fifty-five samples of leaves, petioles, branches and bark of Liquidambar formosana infected with leaf spot were collected from several places of Fujian Province, China. Totally 12 isolates of Pestalotiopsis-like fungi were obtained. Based on phylogenetic analysis of ITS, β-tubulin and tef1 genes in combination with morphological characters, the isolates were identified as Neopestalotiopsis cocoes, N. chrysea, Pestalotiopsis neglecta and P. neolitseae. These species are first reported on Liquidambar formosana, among which N. cocoes is first reported in China. The results of Koch’s postulates showed that N. cocoes could infect the leaves, petioles and branches, N. chrysea could infect the leaves and branches and P. neglecta could infect the petioles and branches, but P. neolitseae appeared to be nonpathogenic. |
