摘要
小穴壳菌属(DothiorelaSac.)(有性阶段是葡萄座腔菌属BotryosphaeriaCas.)、疡壳孢属(DothichizaLib.)、壳囊孢属(CytosporaEhrenb.)、盾壳霉属(ConiothyriumSacc.)等4属真菌是引起树木溃疡病的主要病原真菌类群,是我国现阶段森林的重大有害生物。本文报道了这4个属的真菌基于28SrDNAPCRRFLP和RAPD解析的分类学研究结果,15个供试菌株聚为4类,每一类即一属,在分子水平上证明了其属的传统分类地位的客观性。
The fungal group, including the genera of Dothiorella Sacc. (its sexual phase is Botryosphaeria Cas.), Dothichiza Lib., Cytospora Ehrenb. and Coniothyrium Sacc. presently are the most important forest pathogens in China. In this paper, the tested fifteen isolates of the group are divided into four clusters by the methods of 28S rDNA PCR RFLP and RAPD analyses. Each cluster just corresponds to one genus. So, the objectivity of the traditional taxonomy of these genera is proved in the molecular level.
