Kloeckera taiwanica sp. nov., an ascomycetous apiculate yeast species isolated from mushroom fruiting bodies

Abstract: Three apiculate yeast strains, EJ7M09T , GJ5M15 and GJ15M04, isolated from mushrooms in Taiwan were found to represent a novel species of the genus Kloeckera. The phylogenetically closest relative of this novel species is Hanseniaspora occidentalis, but the type strain of H. occidentalis differed by 4.6 % divergence (25 substitutions; 5 gaps) in the sequence of the D1/D2 domain of the large subunit rRNA gene. This difference clearly suggests that the three strains represent a distinct species. As none of the s… Show more

“…We next examined patterns of transition/transversion ratios and observed a lower transition/transversion ratio in the FEL (0.67 ± 0.02) compared to the SEL (0.76 ± 0.01) (Fig 6C; p < 0.001; Wilcoxon rank–sum test); this finding is in contrast to the transition/transversion ratios found in most known organisms, whose values are substantially above 1.00 [5659]. Altogether, these analyses reveal more base substitutions in the FEL and SEL across all codon positions, a significant AT bias in base substitutions across all Hanseniaspora , and a low transition/transversion ratio across the FEL and SEL.…”

“…Lastly, we examined losses among genes related to meiosis. Although little is known about meiosis and sexual reproduction in Hanseniaspora , recent attempts to induce sporulation and sexual reproduction in different Hanseniaspora species have been unsuccessful [37,41,56,57]. In contrast, other species (i.e., H .…”

“…Its closest known relative is the recently described species of H . taiwanica [4], whose three strains were isolated from fruiting bodies of different mushrooms in Taiwan. These are the only reports of isolations of Hanseniaspora species from mushrooms, making it difficult to infer them as their fundamental niche.…”

“…Kloeckera apiculata (teleomorph Hanseniaspora uvarum), which has a distinctive apiculate or lemon-shaped cell morphology, is widely distributed in natural fruit, such as grapes (Chang et al, 2012). Apiculate yeasts usually utilize few carbon sources (glucose and cellobiose) and have high vitamin requirements, especially for inositol (Romano and Marchese, 1998).…”
