Bensingtonia Ingold emend. Nakase & Boekhout (1986)
The Yeasts, 2011Co-Authors: Takashi Nakase, Feng-yan Bai, Teun BoekhoutAbstract:Publisher Summary This chapter studies the genus Bensingtonia. In the determination of the asexual reproduction it is seen that colonies are whitish, cream, pale pink, brownish-yellow (ochre), brownish, or grayish-red. True hyphae and/or pseudohyphae may be present. Hyphal septa attenuate toward a central pore. Yeast cells are ellipsoidal, ovoid, or elongate. Budding is usually polar, with buds sessile or on short denticles, enteroblastic, and with per-current or sympodial proliferation. Ballistoconidia are bilaterally symmetrical, straight or curved, apiculate, ellipsoidal, ovoid, amygdaliform, falcate, allantoid, or reniform. In the sexual reproduction basidiocarps are absent. Species may be heterothallic. Conjugation of compatible mating types of Bensingtonia intermedia results in the formation of a teleomorphic stage, which is classified in the genus Mastigobasidium. The chapter also discusses physiology/biochemistry and phylogenetic placement of the genus. The type species taken is Bensingtonia ciliata. The key characters of species assigned to the genus Bensingtonia are presented. In the systematic discussion of the species, growth in yeast extract–malt extract (YM) broth, growth on yeast extract–malt extract (YM) agar, Dalmau plate culture on corn meal agar, formation of ballistoconidia, gene sequence accession numbers, type strain, origin of the strains studied, systematics, and ecology are determined.

sporobolomyces diospyroris sp nov sporobolomyces lophatheri sp nov and sporobolomyces pyrrosiae sp nov three new species of ballistoconidium forming yeasts in the agaricostilbum lineage isolated from plants in taiwan
Journal of General and Applied Microbiology, 2005Co-Authors: Satoko Tsuzuki, Hathairat Janngam, Somjit Amin, Morakot Tanticharoen, Sasitorn Jindamorakot, Wanchern Potacharoen, Takashi Nakase, Masako TakashimaAbstract:Three strains of xylose-lacking and ubiquinone-10-having ballistoconidium-forming yeasts isolated from plant leaves collected in Taiwan were found to represent respective new species. In phylogenetic trees constructed based on the nucleotide sequences of 18S rDNA and D1/D2 domain of 26S rDNA, they were located in the Agaricostilbum lineage (Agaricostilbum/Bensingtonia cluster). Since the taxonomic properties of these species coincide with those of the genus Sporobolomyces, they are described as Sporobolomyces diospyroris sp. nov., Sporobolomyces lophatheri sp. nov. and Sporobolomyces pyrrosiae sp. nov., respectively.

Bensingtonia thailandica sp. nov., a novel basidiomycetous yeast species isolated from plant leaves in Thailand.
International journal of systematic and evolutionary microbiology, 2001Co-Authors: B Fungsin, M Hamamoto, V Arunpairojana, J Sukhumavasi, P Atthasampunna, Takashi NakaseAbstract:Ten strains which were characterized by the formation of ballistoconidia, the absence of xylose in whole-cell hydrolysates, the presence of Q-9 as the major ubiquinone isoprenologue, the inability to ferment sugars and positive diazonium blue B and urease reactions were isolated from plant samples collected in Thailand. These isolates were closely related to Bensingtonia phyllada based on the analysis of 18S rDNA sequences. On the basis of the morphological, physiological and chemotaxonomic properties, the 10 isolates were assigned to the genus Bensingtonia. DNA complementarity showed that these isolates were genetically distinct from known species of the genus Bensingtonia. The isolates are described as Bensingtonia thailandica sp. nov. The type strain is strain TY-138T (= JCM 10651T).

Expanding world of ballistosporous yeasts: Distribution in the phyllosphere, systematics and phylogeny.
The Journal of General and Applied Microbiology, 2000Co-Authors: Takashi NakaseAbstract:Ecological and systematic aspects of ballistosporous yeasts inhabiting the phyllosphere of the Asia-Pacific region were reviewed in the light of recent advances. In the past 20 years, the extensive isolation studies of ballistosporous yeasts were carried out in the Asia-Pacific region, and the following new species were found in the phyllosphere of the main island of Japan, of the Ogasawara Islands in the Pacific Ocean, and of Thailand, New Zealand, and the Yunnan Province of China: Bensingtonia ingoldii, B. intermedia, B. miscanthi, B. naganoensis, B. musae, B. sakaguchii, B. subrosea, B. thailandica, and B. yamatoana; Bullera boninensis, B. coprosmaensis, B. hannae, B. huiaensis, B. miyagiana, B. mrakii, B. oryzae, B. penniseticola, B. pseudoalba, B. schimicola, B. sinensis, B. unica, B. variabilis, and B. waltii; Kockovaella imperatae, K. machilophila, K. phaffii, K. sacchari, K. schimae, and K. thailandica; Sporobolomyces blumeae, S. coprosmae, S. coprosmicola, S. dimmenae, S. draycophyllus, S. falcatus, S. griseoflavus, S. inositophilus, S. lactophilus, S. linderae, S. novazealandicus, S. nylandii, S. oryzicola, S. poonsookiae, S. ruber, S. sasicola, S. subbrunneus, S. taupoensis, S. vermiculatus, S. xanthus, and S. yunnanensis; and Udeniomyces megalosporus. Yeast species containing Q-10(H(2)), a monohydrated ubiquinone, have long been considered to be rare yeasts; however, these yeasts were proved to be common in the tropical and subtropical phyllosphere of Asia. The chemotaxonomic and molecular phylogenetic studies based on the sequence analysis of 18S rDNA revealed the heterogeneity of ballistosporous yeasts, which comprised species with polyphyletic phylogenetic origins. A new phylogenetic cluster, Subbrunneus, was newly found in the class Urediniomycetes as the fifth phylogenetical cluster of this class, based on the analysis of 18S rDNA sequences. The Subbrunneus cluster comprises four ballistosporous yeast species found in the phyllosphere of Japan and New Zealand. The future perspectives of basidiomycetous yeast systematics are discussed.

Group I introns found in nuclear small subunit ribosomal RNA genes of the ballistoconidiogenous anamorphic yeast Bensingtonia ciliata and Bensingtonia yamatoana.
Journal of General and Applied Microbiology, 1996Co-Authors: Masako Takashima, Sung-oui Suh, Takashi NakaseAbstract:Four group I introns were found in the nuclear small subunit ribosomal RNA genes (SSU rDNA) of the ballistoconidiogenous anamorphic yeast genus Bensingtonia. Two of them were found in B. ciliata, type species of the genus, with the length of 335 nt and 341 nt. The remaining two were found in B. yamatoana with lengths of 454 nt and 457 nt, respectively. The four introns were located at two different sites within the SSU rDNA. The first insertion site was the same position as group I introns found in the SSU rDNA of Dunaliella parva-5', Dunaliella salina, Protomyces inouyei-5' and Ustilago maydis. The second insertion site was shared among group I introns found in the SSU rDNA of Chlorella ellipsoidea, Hildenbrandia rubra, Pneumocystis carinii and Protomyces inouyei-3'. The putative secondary structures of the introns resembled those of subgroup IC1. Principal coordinate analysis of core regions of 15 group I introns found in SSU rDNA of eukaryotes showed that the sequence of B. ciliata-5' intron resembled that of the B. yamatoana-5' intron, and the sequence of the B. yamatoana-3' intron resembled that of the Protomyces inouyei-5' intron. Bensingtonia ciliata-3' intron had relatively different sequences compared to other group I introns examined. Group I introns in the nuclear SSU rDNA of red and green algae, ascomycetes and basidiomycetes, examined in this study, were scattered on the principal coordinate analysis.

A phylogenetic study of the genus Tilletiopsis, Tilletiaria anomala and related taxa based on the small subunit ribosomal DNA sequences
The Journal of General and Applied Microbiology, 1996Co-Authors: Masako Takashima, Takashi NakaseAbstract:Small subunit ribosomal RNA gene sequences were determined in six species of the genus Tilletiopsis, in addition to Tilletiaria anomala. The phylogenetic trees were constructed for the species of the genus Tilletiopsis, in addition to T. anomala and related taxa by neighbor-joining and maximum likelihood methods. The phylogenetic trees showed that the basidiomycetous yeasts and related taxa were divided into three main clusters. Six species of the genus Tilletiopsis, in addition to T. anomala, constituted a cluster with Sympodiomycopsis paphiopedili, Tilletia caries, Ustilago hordei and U. maydis (cluster 1). In cluster 1, Tilletiopsis species and T. anomala constituted a subcluster with S. paphiopedili and T. caries (cluster lb). The reliability of cluster lb was statistically well supported. On the other hand, Sporobolomyces roseus, the type species of the genus Sporobolomyces, was located at cluster 2 together with Bensingtonia species, Erythrobasidium hasegawianum, Kondoa malvinella, Leucospori-dium scottii, Rhodosporidium toruloides and Sporidiobolus johnsonii. This result clearly showed the phylogenetic divergence between the genera Tilletiopsis and Sporobolomyces; whereas the genera Tilletiopsis and Sporobolomyces have common chemotaxonomic characteristics, i.e., the lack of xylose in the cells and the possession of Q-10 as the major ubiquinone.

Phylogenetic relationships among species of the genus Bensingtonia and related taxa based on the small subunit ribosomal DNA sequences.
The Journal of General and Applied Microbiology, 1995Co-Authors: Masako Takashima, Sung-oui Suh, Takashi NakaseAbstract:Small subunit ribosomal RNA gene sequences were determined in nine species of the ballistoconidium-forming yeast genus Bensingtonia. The phylogenetic trees were constructed for the species of the genus Bensingtonia and related taxa containing Sporobolomyces and Bullera species by neighbor joining, maximum parsimony and maximum likelihood methods. The phylogenetic trees showed that the basidiomycetous yeasts were divided into two main clusters, which were correlated well with the presence or absence of xylose in the cells. In the xylose-lacking basidiomycetous yeasts, seven species out of nine of the genus Bensingtonia constituted a distinct cluster. Bensingtonia ciliata, the type species of the genus, was included in this cluster. The remaining two species, B. intermedia and B. yamatoana, were located in the cluster which contained Rhodosporidium toruloides, Sporidiobolus johnsonii, Sporobolomyces roseus and Leucosporidium scottii. Erythrobasidium hasegawianum was distinctly located in the xylose-lacking basidiomycetous cluster. The molecular phylogeny showed clearly that the genus Bensingtonia was not monophyletic.

Bensingtonia musae sp nov isolated from a dead leaf of musa paradisiaca and its phylogenetic relationship among basidiomycetous yeasts
Journal of General and Applied Microbiology, 1995Co-Authors: Masako Takashima, Sung-oui Suh, Takashi NakaseAbstract:A new species of ballistoconidium-forming yeast, Bensingtonia musae, was isolated from a dead leaf of Musa paradisiaca collected in the southeast seacoast of Bangkok, Thailand. B. musae showed physiological and biochemical characteristics similar to B. ingoldii and B. intermedia. DNA-DNA reassociation experiments, however, showed that it was distinct from these two species. B. musae is easily distinguished from B. ingoldii by the assimilation of sucrose, cellobiose, lactose, melezitose, soluble starch and nitrate, and from B. intermedia by the assimilation of cellobiose, L-arabinose, erythritol and salicin, and the requirement of p-aminobenzoic acid and pyridoxine. In the phylogenetic tree constructed based on small subunit rRNA gene sequences, B. musae was located at a cluster which was composed of B. ciliata, the type species of the genus, B. ingoldii, B. miscanthi, B. naganoensis, B. phylladus, B. subrosea and B. yuccicola. Among these species, B. musae was the most closely related to B. ingoldii.

biodiversity and systematics of basidiomycetous yeasts as determined by large subunit rdna d1 d2 domain sequence analysis
International Journal of Systematic and Evolutionary Microbiology, 2000Co-Authors: Jack W Fell, Alvaro Fonseca, Gloria Scorzetti, Teun Boekhout, Adele StatzelltallmanAbstract:The molecular systematics of 337 strains of basidiomycetous yeasts and yeast-like fungi, representing 230 species in 18 anamorphic and 24 teleomorphic genera, was determined by sequence analysis of the D1/D2 region of the large-subunit rDNA. The data were compared with published sequences of other basidiomycetous fungi. The results demonstrated that the yeast species and genera are phylogenetically distributed among the Microbotryum, Sporidiobolus, Agaricostilbum and Erythrobasidium clades of the Urediniomycetes; the Tremellales, Trichosporonales ord. nov., Filobasidiales and Cystofilobasidiales clades of the Hymenomycetes; and the Ustilaginales, Microstromatales and Malasseziales clades of the Ustilaginomycetes. Genera such as Bensingtonia, Cryptococcus, Rhodotorula and Sporobolomyces are polyphyletic, i.e. they occur in two or more clades. In contrast, other genera, e.g. Bullera, Cystofilobasidium, Fellomyces, Filobasidiella, Filobasidium, Kondoa, Kurtzmanomyces, Leucosporidium, Rhodosporidium, Sporidiobolus and Udeniomyces, are monophyletic. The majority of the species can be identified using D1/D2 analyses, although the internal transcribed spacer region is required to distinguish closely related species. The intergenic spacer region is recommended for additional differentiation of species and strains.

Emendation of the basidiomycetous yeast genus Kondoa and the description of Kondoa aeria sp. nov
Antonie van Leeuwenhoek, 2000Co-Authors: Alvaro Fonseca, João Inácio, Jack W FellAbstract:The genus Kondoa Y. Yamada, Nakagawa & Banno was erected to accommodate a single taxon, K. malvinella (Fell & Hunter) Y. Yamada, Nakagawa & Banno, which was transferred from the teliospore-forming genus Rhodosporidium Banno based on pronounced differences in the 5S and 26S ribosomal RNA (rRNA) nucleotide sequences to R. toruloides Banno. In contrast with the original description, reinvestigation of K. malvinella revealed the formation of transversely septate (auricularioid) basidia that did not arise on teliospores, but formed directly on the dikaryotic mycelium. The four-celled basidia developed sterigmata on which forcibly discharged asymmetric basidiospores (ballistospores) were produced. Additionally, a new taxon emerged from the study of recent isolates, for which the name K. aeria sp. nov. is proposed. This new species produced two-celled auricularioid basidia on hyphae with incomplete clamp connections. Ballistospores arose on the basidia at the tip of sterigmata and, after ejection, germinated by budding. These observations led us to present an emended diagnosis for the genus Kondoa . Analysis of the sequence data from the D1/D2 region of the 26S rRNA gene showed a very close resemblance between K. aeria and K. malvinella in a cluster that also contained several Bensingtonia species. Taxa in this cluster share specific physiological traits and produce characteristic pinkish-cream to mauve colonies; in contrast, formation of ballistoconidia is only observed in the Bensingtonia species. Sequence data supported placement of K. malvinella and K. aeria in the `Agaricostilbum clade' of the Urediniomycetes.

Discussion of teleomorphic and anamorphic genera of heterobasidiomycetous yeasts
1998Co-Authors: Teun Boekhout, Jack W Fell, R.j. Bandoni, Kyung J. Kwon-chung, S.j. Sampaio, A. FonsecaAbstract:Publisher Summary This chapter focuses on the teleomorphic and anamorphic genera of heterobasidiomycetous yeasts. The anamorphic basidiomycetous yeasts are currently assigned to two families: Cryptococcaceae and Sporobolomycetaceae. Cryptococcaceae is restricted to anamorphic heterobasidiomycetous yeasts and yeastlike fungi. The genera of this family are Cryptococcus, Bullera, Fellomyces, Kockovaella, Phaffia, Trichosporon, Tschuchiyaea, Udeniomyces, and perhaps Hyalodendron and Moniliella. Sporobolomycetaceae is restricted to anamorphic yeasts and yeastlike fungi. The type genus of this family is Sporobolomyces. Other genera include Bensingtonia, Kurtzmanomyces, Sterigmatomyces, and Rhodotorula. The Heterobasidiomycetes with yeasts and yeastlike-states are distinguished by basidial morphology, septal pore anatomy, and cell wall composition.The telemorphic genera of heterobasidiomycetous yeasts include various orders including, Sporidiales, Ustilaginales, Tilletiales, Graphiolales, Exobasidiales, and Cryptobasidiales. The exobasidiales are plant parasites, which are found in various plant species. The dikaryotic mycelium grows internally in the host (mostly on leaves of Vacciniaceae in exobasidium), transforming leaves into hypertrophied, inflated, bladdery structures suggestive of fruits. Graphiolales contains a small number of poorly-known species of which only the widely spread Graphiola phoenicis has been studied in detail. The fungus produces minute blister-like sori on palm leaves. Catenate globose cells within the sorus are simple basidia. Meiosis occurs in these cells, and haploid basidiospores bud directly from the basidia to yield yeast colonies.

Phylogenetic classification of yeasts and related taxa within Pucciniomycotina.
Studies in Mycology, 2015Co-Authors: Qi-ming Wang, Teun Boekhout, Andrey Yurkov, Markus Göker, H.t. Lumbsch, Steven D. Leavitt, Marizeth Groenewald, Bart Theelen, Xin-zhan Liu, Feng-yan BaiAbstract:Most small genera containing yeast species in the Pucciniomycotina (Basidiomycota, Fungi) are monophyletic, whereas larger genera including Bensingtonia, Rhodosporidium, Rhodotorula, Sporidiobolus and Sporobolomyces are polyphyletic. With the implementation of the “One Fungus = One Name” nomenclatural principle these polyphyletic genera were revised. Nine genera, namely Bannoa, Cystobasidiopsis, Colacogloea, Kondoa, Erythrobasidium, Rhodotorula, Sporobolomyces, Sakaguchia and Sterigmatomyces, were emended to include anamorphic and teleomorphic species based on the results obtained by a multi-gene phylogenetic analysis, phylogenetic network analyses, branch length-based methods, as well as morphological, physiological and biochemical comparisons. A new class Spiculogloeomycetes is proposed to accommodate the order Spiculogloeales. The new families Buckleyzymaceae with Buckleyzyma gen. nov., Chrysozymaceae with Chrysozyma gen. nov., Microsporomycetaceae with Microsporomyces gen. nov., Ruineniaceae with Ruinenia gen. nov., Symmetrosporaceae with Symmetrospora gen. nov., Colacogloeaceae and Sakaguchiaceae are proposed. The new genera Bannozyma, Buckleyzyma, Fellozyma, Hamamotoa, Hasegawazyma, Jianyunia, Rhodosporidiobolus, Oberwinklerozyma, Phenoliferia, PseudoBensingtonia, Pseudohyphozyma, Sampaiozyma, Slooffia, Spencerozyma, Trigonosporomyces, Udeniozyma, Vonarxula, Yamadamyces and Yunzhangia are proposed to accommodate species segregated from the genera Bensingtonia, Rhodosporidium, Rhodotorula, Sporidiobolus and Sporobolomyces. Ballistosporomyces is emended and reintroduced to include three Sporobolomyces species of the sasicola clade. A total of 111 new combinations are proposed in this study.

Bensingtonia rectispora sp. nov. and Bensingtonia bomiensis sp. nov., ballistoconidium-forming yeast species from Tibetan plant leaves.
International Journal of Systematic and Evolutionary Microbiology, 2011Co-Authors: Qi-ming Wang, Teun Boekhout, Feng-yan BaiAbstract:Five yeast strains isolated from plant leaves collected in south-east Tibet formed cream to brownish colonies and produced asymmetrical ballistoconidia and CoQ-9 as the major ubiquinone. Sequence analysis of the 26S rRNA D1/D2 domain and the internal transcribed spacer region indicated that these strains represented two novel species of the genus Bensingtonia. The names Bensingtonia rectispora sp. nov. (type strain XZ 4C5T = CGMCC 2.02635T = CBS 10710T) and Bensingtonia bomiensis sp. nov. (type strain XZ 33D1T = CGMCC 2.02670T = CBS 10713T) are proposed for the two novel species, which are phylogenetically closely related to Bensingtonia naganoensis, Bensingtonia pseudonaganoensis and the type species of the genus, Bensingtonia ciliata.

Bensingtonia rectispora sp. nov. and Bensingtonia bomiensis sp. nov., novel ballistoconidium-forming yeast species from plant leaves collected in Tibet
International Journal of Systematic and Evolutionary Microbiology, 2011Co-Authors: Qi-ming Wang, Teun Boekhout, F.h. BaiAbstract:Five yeast strains isolated from plant leaves collected in southeast Tibet formed cream to brownish colonies and produced asymmetrical ballistoconidia and CoQ-9 as the major ubiquinone. Sequence analysis of the 26S rRNA D1/D2 domain and the internal transcribed spacer (ITS) region indicated that these strains represented two novel species of the genus Bensingtonia. Bensingtonia rectispora sp. nov. (type strain: XZ 4C5T = CGMCC 2.02635T = CBS 10710 T) and Bensingtonia bomiensis sp. nov. (type strain: XZ 33D1T = CGMCC 2.02670T=CBS 10713T) are proposed for the two new species, which are phylogenetically closely related with Bensingtonia naganoensis, Bensingtonia pseudonaganoensis and the type species of the genus Bensingtonia ciliata.

Bensingtonia Ingold emend. Nakase & Boekhout (1986)
The Yeasts, 2011Co-Authors: Takashi Nakase, Feng-yan Bai, Teun BoekhoutAbstract:Publisher Summary This chapter studies the genus Bensingtonia. In the determination of the asexual reproduction it is seen that colonies are whitish, cream, pale pink, brownish-yellow (ochre), brownish, or grayish-red. True hyphae and/or pseudohyphae may be present. Hyphal septa attenuate toward a central pore. Yeast cells are ellipsoidal, ovoid, or elongate. Budding is usually polar, with buds sessile or on short denticles, enteroblastic, and with per-current or sympodial proliferation. Ballistoconidia are bilaterally symmetrical, straight or curved, apiculate, ellipsoidal, ovoid, amygdaliform, falcate, allantoid, or reniform. In the sexual reproduction basidiocarps are absent. Species may be heterothallic. Conjugation of compatible mating types of Bensingtonia intermedia results in the formation of a teleomorphic stage, which is classified in the genus Mastigobasidium. The chapter also discusses physiology/biochemistry and phylogenetic placement of the genus. The type species taken is Bensingtonia ciliata. The key characters of species assigned to the genus Bensingtonia are presented. In the systematic discussion of the species, growth in yeast extract–malt extract (YM) broth, growth on yeast extract–malt extract (YM) agar, Dalmau plate culture on corn meal agar, formation of ballistoconidia, gene sequence accession numbers, type strain, origin of the strains studied, systematics, and ecology are determined.
