Flowers as a reservoir of yeast diversity: description of Wickerhamiella nectarea f.a. sp. nov., and Wickerhamiella natalensis f.a. sp. nov. from South African flowers and pollinators, and transfer of related Candida species to the genus Wickerhamiella as new combinations.

摘要: Flowers offer favourable microenvironments for yeast growth, and are increasingly recognised as a rich source of novel species. Independent surveys yeasts associated with flowers pollinators in South Africa led to the discovery 38 strains two new Physiological profiles analysis internal transcribed spacer D1/D2 domains large subunit rRNA gene showed that they represent species belong Wickerhamiella clade. We describe nectarea f.a. sp. nov. (type strain EBDCdVSA11-1T, CBS 14162T, NRRL Y-63791T) W. natalensis EBDCdVSA7-1T, 14161T, Y-63790T). extend known range flower-associated discuss ecology phylogenetic relationships clade relation its host biogeography. Examination growth characteristics supports exhibits high degree evolutionary lability, specialisation different niches may occur rapidly. review current status floral biodiversity nectar reservoir diversity, importance In addition, 18 formerly assigned genus Candida reassigned formally Wickerhamiella.
