摘要透孔菌是一类重要的植物病原菌、腐生菌和内生菌，广泛存在于植物寄主上。尽管在中国已经记录了几种间壁透皮菌，但对能够感染林木的物种知之甚少。因此，最近在北京、黑龙江、江苏、江西、陕西和浙江省进行了广泛的调查。本研究对来自16个寄主属的42个代表性分离物的15个种进行了核核糖体内转录间隔区（ITS）、钙调蛋白（cal）、组蛋白H3（his 3）、部分翻译延伸因子1α（tef 1）和β-微管蛋白（tub 2）基因区的DNA序列比较，并对其形态特征进行了分析。经鉴定，有3个已知种，即双点杜氏此外，还收集了12个新的分类群，并将其描述为D.acerigena、D.alangii、D.betulina、D.caryae、D.cercidis、D.chensiensis、D.cinnamomi、D.conica、D.fraxinicola、D.kadsurae、D.padina和D. ukurunduensis。本研究有助于加深对生态经济林木枯梢病病原种类的认识，为我国生态经济林木枯梢病的有效防治提供参考。
Abstract Diaporthe species have often been reported as important plant pathogens, saprobes and endophytes on a wide range of plant hosts. Although several Diaporthe species have been recorded in China, little is known about species able to infect forest trees. Therefore, extensive surveys were recently conducted in Beijing, Heilongjiang, Jiangsu, Jiangxi, Shaanxi and Zhejiang Provinces. The current results emphasised on 15 species from 42 representative isolates involving 16 host genera using comparisons of DNA sequence data for the nuclear ribosomal internal transcribed spacer (ITS), calmodulin (cal), histone H3 (his3), partial translation elongation factor-1α (tef1) and β-tubulin (tub2) gene regions, as well as their morphological features. Three known species, D.biguttulata, D.eres and D.unshiuensis, were identified. In addition, twelve novel taxa were collected and are described as D.acerigena, D.alangii, D.betulina, D.caryae, D.cercidis, D.chensiensis, D.cinnamomi, D.conica, D.fraxinicola, D.kadsurae, D.padina and D.ukurunduensis. The current study improves the understanding of species causing diebacks on ecological and economic forest trees and provides useful information for the effective disease management of these hosts in China.
