摘要

Diaporthe 物种是众所周知的内生菌、汁液菌和病原体，可感染多种植物并导致重要的作物病害。本研究从中国广东省的包心菜病叶中获得了四株 Diaporthe 菌株。利用内部转录间隔区（ITS）、钙调蛋白（cal）、组蛋白 H3（his3）、翻译伸长因子 1-α （tef1）和β-微管蛋白（tub2）五个基因区进行系统发育分析，以确定这些菌株。结果结合形态学发现了两个新的 Diaporthe 物种，分别命名为 D.arecae 物种群中的 D.bauhiniicola 和 D.sojae 物种群中的 D.guangzhouensis。

New species of Diaporthe (Diaporthaceae, Diaporthales) from Bauhiniavariegata in China.

Diaporthe species are known as endophytes, saprobes and pathogens infecting a wide range of plants and resulting in important crop diseases. In the present study, four strains of Diaporthe were obtained from diseased leaves of Bauhiniavariegata in Guangdong Province, China. Phylogenetic analyses were conducted to identify these strains using five gene regions: internal transcribed spacer (ITS), calmodulin (cal), histone H3 (his3), translation elongation factor 1-α (tef1) and β-tubulin (tub2). The results combined with morphology revealed two new species of Diaporthe named D.bauhiniicola in D.arecae species complex and D.guangzhouensis in D.sojae species complex.
