Hannaella dianchiensis sp. nov., a basidiomycetous yeast species isolated from lake water

Abstract

Three strains (YIM-HL1107T, YIM-HL1045, YIM-HL1112) representing a novel yeast species were isolated from surface water samples collected from the Caohai region of Dianchi Lake in Yunnan, south-western China. On the basis of morphological, physiological and biochemical characteristics and sequence analysis of the D1/D2 region of the LSU rRNA gene and the internal transcribed spacer (ITS) region, they were assigned to a novel species of the genus Hannaella. The closest relative to the novel species was Hannaella pagnoccae, but it showed 6.3 % nucleotide differences (34 nt substitutions out of 541 nt) in the D1/D2 region of the LSU rRNA gene and 9.3-9.6 % nucleotide differences (40-41 substitutions and 7-8 gaps out of 430 nt) in the ITS region. The name Hannaella dianchiensis sp. nov. is proposed. The type strain is YIM-HL1107T (=CBS 14191T=CCTCC AY 2015009T), and the MycoBank number is MB 816297.

Among those yeasts, 262 species, including 88 ascomycetous yeasts and 174 basidiomycetous ones, were reported as new species isolated from the country (Bai et al 2001a(Bai et al , b, c, 2002a(Bai et al , b, 2003(Bai et al , 2004(Bai et al , 2016Zhao et al 2002Zhao et al , 2003Zhao et al , 2019Wang et al 2003aWang et al , b, 2004Wang et al , 2006aWang et al , b, 2007Wang et al , b, 2009Wang et al , 2011aWang et al , b, 2012Wang et al , 2015aWang et al , b, c, d, e, 2016Wang et al , 2017Wang et al , 2020Wang et al , 2021Lu et al 2004aLu et al , b, 2017, b, 2010Bai 2005, 2006;Li et al 2006Li et al , 2012Li et al , 2013Li et al , 2019Li et al , 2020Xue et al 2006;Chen et al 2009Chen et al , 2010Chen et al , 2012Chen et al , 2013Ji and Bai 2008;Ji et al 2009;Guo et al 2012Guo et al , 2019Han et al 2012Han et al , 2016Han et al , 2017…”

Characterization of a novel bacteriophage specific to Exiguobacterium indicum isolated from a plateau eutrophic lake

“…The method that isolation of bacterial strains reported by Han et al was used with some modifications. Ten milliliters of mixed and filtered water sample were centrifuged for 10 min at 8000 r min −1 at 4 °C, cell pellets were re‐suspended in 1 ml LB liquid medium and spreaded on chromogenic medium of Staphylococcus aureus (CHROMagar).…”

Characterization of the Complete Mitochondrial Genome of Basidiomycete Yeast Hannaella oryzae: Intron Evolution, Gene Rearrangement, and Its Phylogeny

“…It was proposed to accommodate species closely related to the genera Derxomyces and Dioszegia, which belong to the Bullera sinensis clade of the Luteolus lineage of the Tremellales based on a series of molecular markers (Wang and Bai, 2008;Kaewwichian et al, 2015;Han et al, 2017). So far, about 12 species have been described in this genus, including Hannaella coprosmaensis, Hannaella dianchiensis, Hannaella kunmingensis, Hannaella luteola, Hannaella phyllophila, Hannaella phetchabunensis, Hannaella pagnoccae, Hannaella surugaensis, Hannaella sinensis, Hannaella siamensis, Hannaella zeae, and Hannaella oryzae (Landell et al, 2014;Kaewwichian et al, 2015;Han et al, 2017). These species are found widely distributed on the leaf surfaces of various plants, including rice, wheat, and fruit trees (Han et al, 2017).…”

These species are found widely distributed on the leaf surfaces of various plants, including rice, wheat, and fruit trees (Han et al, 2017). As an important phyllosphere-inhabiting yeast, H. oryzae was considered to play an important role in promoting plant growth and biocontrol.…”
