sp. nov. and sp. nov., two novel yeast species isolated from ephemeral plant substrates Free

Abstract

Four isolates of two novel ascosporogenous species belonging to the clade were obtained from cactus tissues and rotting wood in Brazil. Results of analyses of the sequences of the ITS and D1/D2 domains of the large subunit rRNA gene indicated that the two isolates of the cactophilic species are related to and , yeasts that are associated with cacti and require an organic source of sulfur for growth. We propose the novel species sp. nov. (CBS 16113; MycoBank number: MB 834400) to accommodate these isolates. The other two isolates are phylogenetically related to and , also in the clade. The novel species name sp. nov. (CBS 16316; MycoBank number: MB 834402) is proposed for this species.
