我国间座壳属真菌种类繁多,但对其分类研究滞后.通过对云南省间座壳属标本采集,基于形态学和核糖体内部转录间隔区、β微管蛋白基因、翻译延伸因子基因、钙调蛋白基因和组蛋白基因的DNA序列数据比较进行物种鉴定,描述了分别采集自八角黄皮和可可患病叶片上的间座壳属2个新种——八角黄皮间座壳和可可间座壳,并讨论了其与间座壳属物种的形态和系统发育关系.“,”Diaporthe species in China are highly diverse but still mostly unexplored.In this study,Diaporthe specimens were collected from symptomatic leaves in Yunnan Province.Identification was done using combination of morphology and comparison of DNA sequence data of the nuclear ribosomal internal transcribed spacer(ITS),β-tubulin(TUB),partial translation elongation factor-1a(TEF),calmodulin(CAL)and histone H3(HIS)gene regions.Two new species,viz.D.clausenae and D.theobromatis,were found on Clausena anisata and Theobroma cacao,respectively.They are illustrated and described morphologically and phylogenetic relationships with other Diaporthe species are discussed.
