| 摘 要： | 间座壳属真菌在多种经济上重要的农作物、观赏植物和森林树木上常作为植物病原菌、内生菌或腐生菌被人熟知。本研究调查我国云南省患病植物叶片上的间座壳属真菌,通过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序列数据比较和形态学特征描述了2个新种。它们是分别采集自密花胡颓子和荔枝患病叶片上的密花胡颓子间座壳和荔枝间座壳。

| Abstract: | Diaporthe species are well-known as pathogens,endophytes or saprobes on a range of economically important crops,ornamentals and forest trees.Diaporthe species associated with symptomatic plant leaves from Yunnan Province in China were investigated.Two new species were described based on the analysis of DNA sequence data of the nuclear ribosomal internal transcribed spacer(ITS),β-tubulin(TUB),partial translation elongation factor-1α(TEF),calmodulin(CAL)and histone H3(HIS)regions,in combination with their morphological features.Diaporthe conferta sp.nov.was described from symptomatic leaves of Elaeagnus conferta and D.chinensis sp.nov.was from those of Litchi chinensis. |
