Abstract
Four yeast strains isolated from the nectar of Lantana camara flowers in Pune, India, represent a novel asexual ascomycetous species in the genus Metschnikowia. Phylogenetic analyses of the internal transcribed spacer and D1/D2 regions of the LSU rRNA gene place this species within a subclade of large-spored Metschnikowia species that includes Metschnikowia aberdeeniae, Metschnikowia shivogae and Metschnikowia hibisci. The new species differs by its ability to grow at 35 °C. Whole-genome sequencing and comparative analyses revealed average nucleotide identity values of 76-77% and digital DNA-DNA hybridization values of 14-16% relative to related species, confirming its novelty. The species is described as Metschnikowia ratanii sp. nov., with strain MCC 10123 as the ex-type strain and MCC 9961, MCC 9962 and MCC 9928 as additional cultures. The MycoBank number is MB 858027.
期刊介绍：
Published by the Microbiology Society and owned by the International Committee on Systematics of Prokaryotes (ICSP), a committee of the Bacteriology and Applied Microbiology Division of the International Union of Microbiological Societies, International Journal of Systematic and Evolutionary Microbiology is the leading forum for the publication of novel microbial taxa and the ICSP’s official journal of record for prokaryotic names.
The journal welcomes high-quality research on all aspects of microbial evolution, phylogenetics and systematics, encouraging submissions on all prokaryotes, yeasts, microfungi, protozoa and microalgae across the full breadth of systematics including:
Identification, characterisation and culture preservation
Microbial evolution and biodiversity
Molecular environmental work with strong taxonomic or evolutionary content
Nomenclature
Taxonomy and phylogenetics.
