Abstract

Six interesting fungal strains were isolated during a survey of fungal diversity associated with freshwater; these strains were designated as CNUFC YJW2-22, CNUFC MSW11-6-2, CNUFC HRS5-3, CNUFC MSW242-6, CNUFC DMW2-2, and CNUFC CPWS-1. Based on a polyphasic approach including phylogenetic analyses of internal transcribed space (ITS), large subunit (LSU), beta-tubulin (BenA), and calmodulin (CaM) gene sequences, morphological analyses, the six strains were found to be identical to Acremonium guillematii, Cadophora novi-eboraci, Lectera nordwiniana, Mycoarthris corallina, Talaromyces siamensis, and Tetracladium globosum, respectively. To our knowledge, these are the first records of the rare Lectera, Mycoarthris, and Tetracladium genera in Korea, and the first reports of A. guillematii, C. novi-eboraci, L. nordwiniana, M. corallina, T. siamensis, and Te. globosum in a freshwater environment.

摘要

在一项与淡水相关的真菌多样性调查中分离出六种有趣的真菌菌株；这些菌株被命名为 CNUFC YJW2-22、CNUFC MSW11-6-2、CNUFC HRS5-3、CNUFC MSW242-6、CNUFC DMW2-2 和 CNUFC CPWS-1。基于多相方法，包括内部转录空间 (ITS)、大亚基 (LSU)、β-微管蛋白 (BenA) 和钙调蛋白 (CaM) 基因序列的系统发育分析、形态学分析，发现这六种菌株与顶孢霉属相同分别为guillematii、Cadophora novi - eboraci、Lectera Nordwiniana、Mycoarthris Corallina、Talaromyces siamensis和Tetracladium globosum 。据我们所知，这是韩国对稀有的Lectera、Mycoarthris和Tetracladium属的首次记录，也是A的首次报道。guillematii , C. novi - eboraci , L. Nordwiniana , M . 珊瑚，T . 暹罗，和碲。淡水环境中的球状体。
