Molecular and Morphological Confirmation of Three Undescribed Species of Mortierella from Korea

摘要

Three fungal isolates designated as CNUFC-YR329-1, CNUFC-PTS103-1, and CNUFC-PTS2-1 were discovered during a survey of fungal diversity of the order Mortierellales from freshwater and pine tree rhizosphere soil samples in Korea. The strains were analyzed morphologically and phylogenetically based on the internal transcribed spacer (ITS) and large subunit (LSU) of ribosomal DNA gene sequences. Based on their morphology and phylogeny, the three isolates were identified as Mortierella elongata , M. horticola , and M. humilis , respectively. To the best of our knowledge, M. elongata , M. horticola , and M. humilis , belonging to an undiscovered taxon, have not been previously described in Korea.
