Molecular genetic diversity of the Saccharomyces yeasts in Taiwan: Saccharomyces arboricola, Saccharomyces cerevisiae and Saccharomyces kudriavzevii

Abstract

Genetic hybridization, sequence and karyotypic analyses of natural Saccharomyces yeasts isolated in different regions of Taiwan revealed three biological species: Saccharomyces arboricola, Saccharomyces cerevisiae and Saccharomyces kudriavzevii. Intraspecies variability of the D1/D2 and ITS1 rDNA sequences was detected among S. cerevisiae and S. kudriavzevii isolates. According to molecular and genetic analyses, the cosmopolitan species S. cerevisiae and S. kudriavzevii contain local divergent populations in Taiwan, Malaysia and Japan. Six of the seven known Saccharomyces species are documented in East Asia: S. arboricola, S. bayanus, S. cerevisiae, S. kudriavzevii, S. mikatae, and S. paradoxus.

Saccharomyces eubayanusandSaccharomyces uvarumassociated with the fermentation ofAraucaria araucanaseeds in Patagonia

“…This result agrees with those reported by Libkind et al . () and supports the idea that the cold forests from Patagonia may be an unfavorable ecosystem for the non‐cryotolerant Saccharomyces species such as S. cerevisiae or S. paradoxus , which is easily isolated in other regions using the same methodology (Sampaio & Gonçalves, ; Lopes et al ., ; Naumov et al ., ). The climatic conditions of the sampling areas in this study, characterized by temperatures between −4 and 11 °C, are highly selective and make Northwestern Patagonia a region suitable only for the cryotolerant species S. eubayanus and S. uvarum .…”

“…The climatic conditions of the sampling areas in this study, characterized by temperatures between −4 and 11 °C, are highly selective and make Northwestern Patagonia a region suitable only for the cryotolerant species S. eubayanus and S. uvarum . Interestingly, S. kudriavzevii , the other cryotolerant species of the genus isolated from European and Asian areas of similar climatic conditions (Sampaio & Gonçalves, ; Lopes et al ., ; Naumov et al ., ), was not isolated in this study or in the previous study by Libkind et al . (), perhaps due to competitive exclusion, as suggested by Sampaio & Gonçalves ().…”

Saccharomyces eubayanus and Saccharomyces arboricola reside in North Island native New Zealand forests

“…Two competing hypotheses regarding the origin of this group have recently been put forward: one suggests a Far East Asian origin (Wang et al ., ; Bing et al ., ); the other suggests a Gondwanan one (Almeida et al ., ; Peris et al ., ). In support of the Far East Asia hypothesis is the fact that the greatest species diversity is found in this area given the sampling efforts so far: all species in the group have been uncovered here, with S. mikatae and S. arboricola not yet reported elsewhere (Naumov et al ., 1997; 2000; 2013; Wang and Bai, ; Wang et al ., ; Almeida et al ., ; Bing et al ., ). In addition, the genetic diversity of S. eubayanus , S. paradoxus , S. kudriavzevii and S. cerevisiae are the same or higher in Far East Asian populations than elsewhere (Tsai et al ., ; Hittinger et al ., ; Bing et al ., ).…”
