Abstract

The genus Aspergillus is commonly isolated from various marine and terrestrial environments; however, only a few species have been studied in rhizosphere soil. As part of the Korean indigenous fungal excavation project, we investigated fungal diversity from rhizosphere soil, focusing on Aspergillus species. A total of 13 strains were isolated from the rhizosphere soil of three different plants. Based on phylogenetic analysis of β-tubulin and calmodulin and morphological characteristics, we identified five Aspergillus species. A. calidoustus and A. pseudodeflectus were commonly isolated from the rhizosphere soil. Four species were confirmed as unrecorded species in Korea: A. calidoustus, A. dimorphicus, A. germanicus, and A. pseudodeflecuts. The detailed morphological descriptions of these unrecorded species are provided.

曲霉属通常从各种海洋和陆地环境中分离出来；然而，仅对根际土壤中的少数物种进行了研究。作为韩国本土真菌挖掘项目的一部分，我们研究了根际土壤的真菌多样性，重点关注曲霉属物种。从三种不同植物的根际土壤中总共分离出 13 个菌株。基于β-微管蛋白和钙调蛋白的系统发育分析以及形态特征，我们鉴定了五种曲霉菌。 A. calidoustus和A .假偏转菌通常从根际土壤中分离出来。韩国有四个物种被确认为未记录物种： A .卡利杜斯图斯， A .双态性， A .日耳曼库斯和A .伪偏转。提供了这些未记录物种的详细形态描述。
