The diversity of culturable yeasts in the phylloplane of rice in Thailand Savitree Limtong & Rungluk Kaewwichian One hundred and fifty-six yeast strains were obtained by the enrichment technique from the phylloplanes of 85 rice leaf samples collected from seven provinces in Thailand. On the basis of the D1/D2 domain of the large subunit rRNA gene sequence analysis, 156 strains were identified as 34 known species in 18 genera consisting of 25 species in 13 genera of the phylum Ascomycota and nine species in five genera of the phylum Basidiomycota. The species in the phylum Ascomycota comprised 24 species in 12 genera of the order Saccharomycetales and one species viz. Yarrowia lipolytica in Saccharomycetales incertae sedis. The 24 species viz. Candida glabrata in the Nakaseomyces clade of Saccharomycetaceae, Candida jaroonii, Candida membrani- faciens and Candida terebra in the Yamadazyma clade of Debaryomycetaceae, Candida pseudolambica in the Pichia clade of Pichiaceae, Candida ruelliae in the Metschnikowia clade of Metschnikowiaceae, and three unaffiliated clade Candida species (Candida catenulata, Candida rugosa and Candida tropicalis); Clavispora lusitaniae, Kodamaea ohmeri, Metschnikowia koreensis and Metschnikowia lopburiensis in Metschnikowiaceae; Cyberlindnera fabianii, Cyberlindnera rhodanensis and Wickerhamomyces ciferrii in Wickerhamomycetaceae; Debaryomyces nepalensis, Meyerozyma caribbica, Meyerozyma guilliermondii, Millerozyma koratensis, and Yamadazyma mexicanum in Debaryomycetaceae; Pichia kudriavzevii in Pichiaceae; and Lachancea thermotolerans in Saccharomycetaceae. The species in Basidiomycota viz. Cryptococcus flavescens, Cryptococcus laurentii, Cryptococcus aff. laurentii and Cryptococcus rajasthanensis in the Tremellales lineage, Bulleromyces clade, Tremellales, Tremellomycetes, Agaricomycotina; Pseudozyma antarctica and Pseudozyma aphidis in Ustilaginales, Ustilaginomycetes, Ustilaginomycotina; Rhodotorula taiwanensis and Sporobolomyces blumeae in Sporidiobolales, Microbotryomycetes, Pucciniomycotina; and Trichosporonasahii in Trichosporonales, Tremellomycetes, Agaricomycotina. The most prevalent species was R. taiwanensis with a 23% frequency of occurrence followed by Candida tropicalis (16%) and Cryptococcus fabianii (12%). _______________________________________ Abstract of an article in Ann.
