Abstract

During a survey of fungal diversity of the order Mortierellales, a zygomycete strain, EML-YS717-1, was isolated from a freshwater sample collected from the Yeongsan River in Gwangju, Korea. Based on its morphological characteristics and a phylogenetic analysis of the internal transcribed spacer (ITS1 and ITS2) and 5.8S rDNA sequences, the strain was identified as Mortierella minutissima. To the best of our knowledge, M. minutissima, has not previously been authentically reported in Korea.

Figures & Tables

Phylogenetic tree of EML-YS717-1 and EML-YS717-2 and related species based on maximum likelihood analysis of internal transcribed spacer (ITS) rDNA sequences. Sequence of was used as the outgroup. Bootstrap support values of ≥50% are indicated at the nodes. The bar indicates the number of substitutions per position. The group and clades on tree was named based on the classification system constructed by Wagner et al. [2].
