Abstract

In a study of the fungal diversity on Ulleung Island in Korea, three novel strains of Penicillium were isolated. Different sites on Ulleung Island were selected for collecting endophytic fungi, and three endophytic fungal strains showed unique morphological characteristics. DNA sequence of the internal transcribed spacer, β-tubulin, calmodulin, and RNA polymerase II second largest subunit regions of the strains were analyzed and they showed unique taxonomic position from the other species of Penicillium section Sclerotiora. The new strains were named Penicillium ulleungdoense sp. nov. As the novel endophytic Penicillium taxa were discovered in a unique environment, the data could be meaningful for understanding the geographical distribution of Ascomycetes on Ulleung Island.

摘要

在韩国Ulleung岛的真菌多样性研究中，分离出了三株新的青霉菌株。选择了Ulleung岛上的不同地点来收集内生真菌，并且三种内生真菌菌株均表现出独特的形态特征。分析了该菌株内部转录间隔区，β-微管蛋白，钙调蛋白和RNA聚合酶II第二大亚基区域的DNA序列，它们显示了与青霉菌节菌其他物种不同的独特分类学位置。新菌株被命名为Penicillium ulleungdoen se sp。十一月 作为新型内生青霉 在一个独特的环境中发现了分类单元，这些数据对于了解乌勒贡岛上子囊菌的地理分布可能是有意义的。
