“…The three nucleotide differences found in the D1/D2 region in contrast to the 46 differences in the ITS region between CBS 8583 T and C. naeodendra can be seen as a good example why the D1/D2 region, a region that is still commonly used as an exclusive marker in studies for the identification and delimitation of species belonging to commonly known yeast genera (Nakase et al 2008, 2010a, b, Ganter et al 2010, de Garcia et al 2010, Mestre et al 2010), alone is often not sufficient for species delimitation in yeasts; especially within the Yamadazyma clade. Several other yeast taxonomic studies have also proven this to be true in species from other genera such as Blastobotrys (Kurtzman 2007), Debaryomyces (Groenewald et al 2008), Saturnispora (Canelhas et al 2010) and Rhodotorula (Libkind et al 2010), and shown that sequences of additional regions are necessary in order to separate the closely related species from one another.…”

In a taxonomic study of yeasts that have been isolated in French Guiana and Thailand, five yeast strains isolated from plants were found to belong to the Yamadazyma clade of Saccharomycotina. On the basis of morphology, physiology and the nucleotide divergence in the D1/D2 domain of the 26S nuclear ribosomal RNA (nrRNA) gene, as well as the internal transcribed spacers (ITS) domain of the nrRNA gene operon, these strains were identified to represent three novel species in this teleomorphic clade. An additional isolate, that is publicly available from the CBS yeast collection and isolated from Taiwan, was found to be similar to one of the novel species described from Thailand. Yeast species belonging to the Yamadazyma clade have previously been described as members of the Candida membranifaciens clade. These species are widely distributed and were isolated from diverse habitats, including water, plants, animals and guts of insects and termites. In the present study the ITS region is shown to be a valuable region for species identification within this clade, and the novel species proposed are Candida vaughaniae (ex-type strain CBS 8583), Candida khao-thaluensis (ex-type strain CBS 8535) and Candida tallmaniae (ex-type strain CBS 8575).

“…In the latest edition of The Yeasts, a Taxonomic Study, six ascosporogenous species (Yamadazyma philogaea, Y. akitaensis, Y. mexicana, Y. nakazawae, Y. scolyti, Y. triangularis) and 23 asexual species assigned to the genus Candida were placed in the Yamadazyma clade . Since then, additional species of the genus Candida in this clade have been found Nakase et al, 2008;AmIn et al, 2011;Buddie et al, 2011;Burgaud et al, 2011;Groenewald et al, 2011) and many novel species of the genus Yamadazyma have been discovered and described such as Yamadazyma terventina, Y. siamensis, Y. phyllophila, Y. paraphyllophila, Y. ubonensis, Y. insecticola, Y. epiphylla, Y. riverae, Y. dushanensis and Y. kitorensis (Ciafardini et al, 2013;Kaewwichian et al, 2013b;Junyapate et al, 2014;Jindamorakot et al, 2015;Lopes et al, 2015;Wang et al, 2015;Nagatsuka et al, 2016). In addition, three known species of the genus Candida were transferred to the genus Yamadazyma as novel combinations, namely Yamadazyma olivae, Y. tumulicola and Y. takamatsuzukensis (Nagatsuka et al, 2016).…”

Strain DMKU-CE23 T representing a novel yeast species was isolated from tissue of a corn leaf (Zea may L.) collected in Thailand. A phylogenetic analysis based on the combined sequences of the internal transcribed spacer (ITS) region and the D1/D2 region of the LSU rRNA gene indicated that strain DMKU-CE23 T belongs to the Yamadazyma clade and is clearly distinct from other related species. It therefore represents a novel species of the genus Yamadazyma although the formation of ascospores was not observed. The strain of novel species was most closely related to the type strain of Yamadazyma epiphylla but with 5.1 % nucleotide substitutions in the ITS region and 3.7 % nucleotide substitutions in the D1/D2 region of the LSU rRNA gene. The name Yamadazyma endophytica f.a., sp. nov. is proposed. The type strain is DMKU-CE23 T (=CBS 14163 T =TBRC 5174 T ).

“…Members of the Yamadazyma clade exhibit an association with the gut of beetles and other insects, flowers, tree exudates, plants, mushroom, deep-sea coral, water samples, and marine and mangrove habitats (Nakase et al , 2008; Burgaud et al , 2011; Groenewald et al , 2011; Kurtzman, 2011; Lachance et al , 2011; Kaewwichian et al , 2013; Junyapate et al ., 2014). According to these reports, 20 species in the Yamadazyma clade have been isolated from the gut or frass of insects and 10 species have been obtained from plants.…”

“…In Kurtzman (2011), Yamadazyma philogaea , the type species of the genus, as well as Y. akitaensis , Y. mexicana , Y. nakazawae , Y. scolyti , Y. triangularis and 28 Candida species are placed in the Yamadazyma clade. Since then, many novel species of the genus Candida in this clade have been described, for example Candida kanchanaburiensis , C. khao-thaluensis , C. vaughaniae , C. tallmaniae , C. oceani , C. sirachaensis , C. sakaeoensis , C. phyllophilla and C. vitiphila (Nakase et al , 2008; Burgaud et al , 2011; Groenewald et al , 2011; Limtong et al ., 2012; Limtong & Kaewwichian, 2013). Recently, five species of the genus Yamadazyma , namely Y. terventina , Y. siamensis , Y. phyllophila , Y. paraphyllophila and Y. ubonensis , were proposed from strains isolated in Italy, Taiwan and Thailand (Ciafardini et al ., 2013; Kaewwichian et al , 2013; Junyapate et al ., 2014).…”

Two yeast strains representing two novel yeast species were isolated from frass of an unidentified insect (ST-78 T) and the external surfaces of rice leaves (YE170 T) collected in Thailand. The two strains were genetically, morphologically and phenotypically distinct from recognized species and were found to represent two novel species of the genus Yamadazyma although formation of ascospores was not observed. In terms of pairwise sequence similarity of the D1/D2 region of the large subunit rRNA gene, the closest relative of strain ST-78 T was Candida lessepsii CBS 9941 T but with 3.8 % nucleotide substitutions, while the closest relative of strain YE170 T was strain ST-78 T but with 4.3 % nucleotide substitutions. Analysis of the sequences of the internal transcribed spacer 1 and 2 (ITS1-2) regions revealed that strain ST-78 differed from C. lessepsii CBS 9941 T by 8.8 % nucleotide substitutions and from strain YE170 T by 9.4 % nucleotide substitutions. The result of pairwise sequence similarity of the D1/D2 and ITS1-2 regions together with phylogenetic analysis indicated that strains ST-78 T and YE170 T represented two novel species within the Yamadazyma clade. The names Yamadazyma insecticola f.a., sp. nov. (type strain ST-78 T 5BCC 8314 T 5NBRC 110421 T 5CBS 13382 T ; MycoBank no. MB810546) and Yamadazyma epiphylla f.a., sp. nov. (type strain YE170 T 5BCC 63466 T 5NBRC 110423 T 5CBS 13384 T ; MycoBank no. MB810547) are proposed for the two novel yeast species.
