类开费曲霉Aspergillus keveioides——曲霉属焦曲霉组一新种

摘要

A new Aspergillus species,A.keveioides (AS3.15305T=CBS 132737) was isolated from soil in Shandong Province,China.Morphologically,it resembles A.pseudodeftectus,A.germanieus,A.insuetus,A.keveii and A.thesauricus,but is readily different from them by sparse sporulation,smooth and warty stipe walls with conspicuous concretions,and globose warty conidia.The analyses of partial calmodulin gene (CaM),β-tubulin gene (BenA) and rDNA ITS 1-5.8S-ITS2sequence data showed that although A.keveioides was accommodated in the clade with A.keveii,A.insuetus,A.germanicus and A.thesauricus,it is distinctive and lack close relatives among described species of Aspergillus sect.Usti.%报道分离自中国山东泰山土壤的曲霉属焦曲霉组的一个新种——类开费曲霉Aspergillus keveioides.基于形态学及钙调蛋白、β-微管蛋白基因部分序列和核糖体DNAITSl-5.8S-ITS2序列分析的证据支持新种的建立.
