Abstract

During a survey of undiscovered taxa in Korea, two zygomycete fungal isolates, EML-BT5-1 and EML-BT5-2, were isolated from the seed of a pumpkin (Cucurbita pepo) fruit in Korea. Based on their morphological characteristics and a sequence analysis of four genes, ITS1-5.8S-ITS2, 18S, 28S rDNA, and EF-1α, the isolates were confirmed to be Syncephalastrum monosporum in the family Syncephalastraceae. To our knowledge, the zygomycete fungal species S. monosporum has not been previously described in Korea.

Figures & Tables

Phylogenetic tree of EML-BT5-1 and EML-BT5-2 based on a maximum likelihood analysis of internal transcribed spacer (A) and 28S (B) rDNA sequences. Sequence of was used as an outgroup. Bootstrap values with more than 50% support in 1,000 replications are shown above branches. The bar indicates the number of substitutions per nucleotide position.
