Aureobasidium mangrovei sp nov., an ascomycetous species recovered from Hara protected forests in the Persian Gulf, Iran

摘要

A new ascomycetous black yeast-like species was recovered from healthy plant (Avicennia marina) of Hara protected mangrove forests at Qeshm Island, Iran. Morphological, physiological analysis as well as a molecular analysis of the internal transcribed spacer (ITS) and partial large ribosomal subunit (D1/D2 domains) confirmed the placement of this strain in the genus Aureobasidium and based on considerable sequence divergence, distinguishable cardinal growth temperatures and salt tolerance a new species Aureobasidium mangrovei sp. nov. is proposed. However, the type strain micro-morphologically is not clearly distinguishable from other members of the genus. The type strain, Aureobasidium mangrovei was preserved in a metabolically inactive state at the Iranian Biological Resource Centre, Tehran, Iran as IBRC-M 30265(T) and the ex-type culture is deposited in the CBS yeast collection of the Westerdijk Fungal Biodiversity Institute, Utrecht, The Netherlands as CBS 142205(T). The GenBank accession numbers for the nucleotide sequences of the large subunit ribosomal DNA and ITS region are KY089084 and KY089085, respectively. The MycoBank number of the new species is MB 823444.
