査読あり, 英語, MEDICAL MYCOLOGY, The loss of parts of chromosome 7 followed by the insertion of URA cassette into RB2 on MRS in Candida albicans strain CAI-4, Shin-Ichi Iwaguchi; Mina Suzuki; Naomi Sakai; Koji Yokoyama; Takahito Suzuki, Clinical isolates of the medically important fungus Candida albicans show electrophoretic karyotype variations. Chromosome translocation is considered to be one of the possible mechanisms of karyotype variation and has been shown to occur very frequently at or near the unique repeated DNA sequences which comprise the Major Repeat Sequence (MRS) on the genome. The MRS consists of the repeated sequences RB2, RPS, and HOK. We previously showed the insertion at the RB2 region might initiate chromosome translocation in strain STN22u2 of C. albicans. To ask whether the insertion of a URA cassette into the RB2 but not into RPS and HOK causes chromosome translocation in C. albicans strains, we transformed three URA cassettes into strain CAI-4, which is commonly used as a host strain for gene knockout experiments. We found chromosome rearrangements followed the insertion of URA cassettes into RB2 in strain CAI-4. Three transformants had an extra chromosome showing the loss of the 7A and 7C region from one chromosome 7 homologue. The recombination occurred at or after the insertion of URA cassette into RB2. Insertion there seems to cause chromosome rearrangement and thus RB2 is considered one of the important elements for initiation of chromosome rearrangement., 2008年, 46, 7, 655, 663, 研究論文(学術雑誌), 10.1080/13693780801989783
査読あり, 英語, YEAST, Chromosome translocation induced by the insertion of the URA blaster into the major repeat sequence (MRS) in Candida albicans, S Iwaguchi; M Suzuki; N Sakai; Y Nakagawa; PT Magee; T Suzuki, Ellectrophoretic karyotype studies have shown that clinical isolates of Candida albicalls have extensive chromosome length polymorphisms. Chromosome translocation is one of the causes of karyotypic variation. Chromosome translocation events have been shown to occur very frequently at or near the major repeat sequence (MRS) on chromosomes. The MRS consists of the repeated sequences RB2, RPS and HOK, and the repeated sequences are considered to be the template for recombination. To investigate which element of the MRS is important for chromosome translocation, we constructed three cassettes, each containing a URA blaster and sequences homologous to one of the repeats, for insertion into the MRS region on the chromosomes. The ura3 strain STN22u2, which shows a stable, standard karyotype, was transformed with each construct. Insertion events with each cassette occurred at almost all chromosomes. Insertion into the RB2 repeat, but not into the RPS repeat, was accompanied by chromosome translocation in some transformants: chromosome translocations between chromosomes R and 7 and chromosomes I and 7 were found, as well as deletions of 7A and 7C from chromosome 7. We conclude that the insertion at the RB2 region may initiate chromosome translocation in C. albicans.

査読あり, 英語, YEAST, Extensive chromosome translocation in a clinical isolate showing the distinctive carbohydrate assimilation profile from a candidiasis patient, SI Iwaguchi; M Sato; BB Magee; PT Magee; K Makimura; T Suzuki, Variation of the electrophoretic karyotype is common among clinical strains of Candida albicans and chromosome translocation is considered one of the causes of karyotypic variation. Such chromosome translocations may be a mechanism to confer phenotypic diversity on the imperfect fungus C. albicans. A clinical strain, TCH23, from a vaginal candidiasis patient shows distinct carbohydrate assimilation profile, serotype B, no chlamydospore formation and an atypical karyotype (Asakura et al, 1991). To examine the taxonomic relationship among C. albicans, Candida dubliniensis and this strain, we sequenced the internal transcribed spacer 1 (ITS1) of nuclear ribosomal DNA. The ITS1 sequence of TCH23 was identical with that of C. albicans but not of C. dubliniensis. Thus, strain TCH23 was classified as a variant of C albicans with an atypical phenotype. The chromosomal DNAs of this strain were resolved into 13 bands on pulse-field gel electrophoresis (PFGE). Using DNA probes located at or near both ends of each chromosome of C. albicans, we investigated the chromosome organization of this strain. Referring to the SfiI map of C albicans 1006 (Chu et al, 1993), we found that seven chromosomal DNA bands in strain TCH23 were reciprocal chromosome translocations. One homologue from chromosomes 1, 2 and 6 and both homologues from chromosomes 4 and 7 participated in these events. One translocation product was composed of three SfiI fragments, one each from chromosomes 2, 4 and 7. We deduced the breakpoints of chromosome translocation from the physical map of this strain; between 1J and 1J1, between 2A and 2U, both ends of 4F2, between 6C and 6O and both ends of 7F.

査読あり, 英語, YEAST, High-frequency occurrence of chromosome translocation in a mutant strain of Candida albicans by a suppressor mutation of ploidy shift, S Iwaguchi; T Kanbe; T Tohne; PT Magee; T Suzuki, Significant occurrence of high-ploidy cells is commonly observed among many Candida albicans strains. We isolated two isogenic strains, STN21 and STN22, each from a half sector of a colony obtained after mild UV-irradiation of a Arg(-) derivative of CBS5736. The two strains were different from each other in ploidy states and chromosome organization. Although cells of STN22 were homogeneous in size and had a single nucleus, high-ploidy cells, with either a single large nucleus or several nuclei, were present together with apparently normal cells with a single nucleus in the cell population of STN21. Flow cytometry showed that STN22 was a stable diploid; however, STN21 seemed to be the mixture of different ploidy states, including diploid and tetraploid. The phenotype of STN21 containing high-ploidy cells is referred to here as the Sps(-) phenotype (suppressor of ploidy shift). STN22 showed a typical electrophoretic karyotype similar to strain 1006 in C. albicans. However, an extra chromosomal band appeared in some clones of STN21 at high frequency. By assignment of several DNA probes, this extra chromosome was shown to be a translocation of the 7F-7G portion of chromosome 7 with the 470 kb DNA segment containing H SfiI fragment from chromosome 4. Thus, this extra chromosome is a hybrid of 4H and 7F-7G. Since the isogenic Sps(+) strain STN22 exhibited no extra chromosome bands, a correlation is suggested between the Sps(-) phenotype and the occurrence of chromosome translocations.

査読あり, 英語, MICROBIOLOGY-UK, Depolarized cell growth precedes filamentation during the process of ethanol-induced pseudohyphal formation in the yeast Candida tropicalis, T Suzuki; Y Imanishi; S Iwaguchi; T Kamihara, Ethanol has been reported to cause mycelial growth in Candida tropicalis Pk233, and mycelial growth has also been shown to be abolished by concomitant addition of myo-inositol. In this study, the process of ethanol-induced mycelial growth in this organism was examined in combination with cytological characterization of actin localization, Cultivation with ethanol gave biphasic growth curves. During the first growth phase (doubling time 2.4 h), there was an accumulation of swollen spherical yeast cells, instead of the oblong ones observed in the control culture, followed by the appearance of spherical daughter cells in chains. Randomly distributed actin patches were observed on these swollen yeast cells and the bud initiation sites of these cells appeared random. These observations suggested that ethanol caused depolarization of cell growth during the first phase. During the second growth phase (doubling time 7.4 h), pseudohyphal cells appeared, projecting from the swollen yeast cells. Activity of chitinase in the control culture rose during the exponential phase. In the ethanol culture the activity stayed at a low level throughout the growth phases. When pseudohyphal cells were transferred to fresh ethanol medium, yeast cells appeared from pseudohyphal filaments and changed their shape to spherical, and filamentation appeared to be inhibited during the first phase. From these observations, an initial effect of ethanol on C. tropicalis cells appeared to be depolarization of cell growth, and the resulting swollen cells grew as polar pseudohyphal cells. In the culture supplemented with both ethanol and inositol, or with both ethanol and sorbitol, the accumulation of swollen cells was not observed and single yeast cells with normal oblong shape were seen throughout the growth phases., 1998年02月, 144, 403, 410, 研究論文(学術雑誌)

査読あり, 英語, JOURNAL OF CLINICAL MICROBIOLOGY, STRAIN RELATEDNESS OF CANDIDA-ALBICANS STRAINS ISOLATED FROM CHILDREN WITH LEUKEMIA AND THEIR BEDSIDE PARENTS, M DOI; M HOMMA; SI IWAGUCHI; K HORIBE; K TANAKA, Candida yeasts are occasionally recovered from patients with leukemia in spite of antifungal therapy used during chemotherapy. It is not yet known whether yeasts in these patients are of endogenous or exogenous origin. We examined the strain relatedness of Candida albicans isolated from three patients with leukemia (A, B, and C) and their bedside parents using pulsed-field gel electrophoresis (PFGE), restriction fragment length polymorphism (RFLP) by SmaI digestion, and the Southern hybridization patterns of the RFLPs by the C. albicans-specific probe RPS1. SmaI digestion and Southern hybridization by RPS1 showed identical or similar patterns among Candida isolates in patient A and his mother, although their karyotypes were different. Isolates from patient B and both parents showed identical electrophoretic karyotypes, SmaI digestion patterns, and hybridization patterns. Since electrophoretic karyotypes are more variable than RFLPs and their hybridization patterns, the identity of the last two suggests a close relatedness between strains. Our results also suggest that transmission of yeast strains may have occurred between patient A and his mother and between patient B and her parents. Isolates from patient C and her mother are thought to have originated from different strains, since different patterns were obtained in electrophoretic karyotypes, SmaI digestion patterns, and Southern hybridization patterns., 1994年09月, 32, 9, 2253, 2259, 研究論文(学術雑誌)
査読あり, 英語, JOURNAL OF BACTERIOLOGY, DIVERSITY OF TANDEMLY REPETITIVE SEQUENCES DUE TO SHORT PERIODIC REPETITIONS IN THE CHROMOSOMES OF CANDIDA-ALBICANS, H CHIBANA; SI IWAGUCHI; M HOMMA; A CHINDAMPORN; Y NAKAGAWA; K TANAKA, In a previous study, a repeated sequence, RPS1, was cloned from the genomic DNA of Candida albicans. It was 2.1 kb in length and was tandemly repeated in a limited region of almost all of the chromosomes. In this study, we examined and characterized the diversity of the repeating structure of the RPS units. RPS units were of 2.1, 2.3, 2.5, and 2.9 kbp in length after digestion of the genomic DNA with SmaI and 2.1 and 2.3 kbp after digestion with PstI, with the differences being multiples of approximately 0.2 kbp. Moreover, one or two types of RPS unit were present specifically on each chromosome. We cloned 14 RPS units from the mixed DNA of chromosomes 1 and 2 and 59 RPS units from chromosome 6. These RPS units were classified into four types by their SfiI digestion profiles and chromosomal origins. Sequence comparisons revealed a tandem arrangement of internal, small repeating units of 172 bp. This unit of repetition was designated alt (C. albicans tandem repeating unit). The size of RPS units was variable, with sizes representing a series of increments of approximately 0.2 kbp that corresponded to the alt sequence. By contrast, the sequences other than the tandem repeats of alts were highly conserved, with homology of more than 98% among all cloned RPS units. These results suggested that RPS plays an important role in the organization and function of the chromosomes of C. albicans even though the actual function of RPS has not yet been clarified. Structural features of RPS that contains the repeated art sequence are discussed in relation to human alpha-satellite DNA with its tandem repeats of about 170 bp that are similar in size to alt, the repetition of which is responsible for the variations in the size of the higher-order repeats., 1994年07月, 176, 13, 3851, 3858, 研究論文(学術雑誌)
査読あり, 英語, JOURNAL OF GENERAL MICROBIOLOGY, CLONAL SIZE-VARIATION OF RDNA CLUSTER REGION ON CHROMOSOME-XII OF SACCHAROMYCES-CEREVISIAE, A CHINDAMPORN; SI IWAGUCHI; Y NAKAGAWA; M HOMMA; K TANAKA, Using pulsed-field gel electrophoresis (PFGE), we have demonstrated clonal variation in the size of chromosome XII in a diploid strain of Saccharomyces cerevisiae X2180-2D. The sizes of the two chromosome XII homologues were very different: 2600 (L-type) and 1450 kb (S-type). The frequency with which we detected clonal size variation in the diploid, compared to that of the parental clones, was about 15-50% of the progeny clones and the range of the size variation of the homologues was 2580-2680 kb (L-type) and 1340-1500 kb (S-type), respectively. The homologue of the L-type appeared to be more frequently variable than that of the S-type. The size variation was shown to be derived from size changes in the rDNA cluster region, which is present in chromosome XII, by digesting the chromosome with XhoI, whose cutting site is not present in a rDNA repeat unit, and hybridizing to rDNA probes. The clonal size variation was also investigated in haploids from spores after meiosis. The L-type and S-type chromosomes segregated 2:2 in an ascus and the sizes of all the S-type chromosomes were shifted up, compared to the original diploid, though the L-type ones were stable. The S-type sizes of 1340, 1450 and 1780 kb in the original diploids changed into the ranges of 1475-1610 kb, 1520-1680 kb and 1820-2010 kb, respectively, in the segregants. Furthermore, we observed that the size of S-type chromosomes in haploid cells was gradually increasing in mitosis during successive subcultures. The rDNA units appeared to be amplified on the S-type chromosome., 1993年07月, 139, 1409, 1415, 研究論文(学術雑誌)
査読あり, 英語, JOURNAL OF GENERAL MICROBIOLOGY, ISOLATION AND CHARACTERIZATION OF A REPEATED SEQUENCE (RPS1) OF CANDIDA-ALBICANS, S IWAGUCHI; M HOMMA; H CHIBANA; K TANAKA, A repeated sequence, named RPS1, approximately 2 kb in size, is found mainly in chromosome 6, the second most variable chromosome among the eight chromosomes of Candida albicans. Most of the RPS1 units of chromosome 6 seem to be located within a single region of about 100 kb in strain FC18. In both strains FC18 and NUM812, a part of RPS1 is apparently tandemly repeated. A unit of RPS1 has been cloned and sequenced. It consists of 2114 bp and has a GC content of 40 mol %. The repeat unit contains smaller repeats of about 80-170 bp which are called REP1, REP2, REP3, REP4 and REP5; REP2 is duplicated. The small repeats are classified into two groups by their homology. One comprises REP1, REP2 and REP5, and the other REP3 and REP4. They are termed the REP1 and REP3 families, respectively. The two families both contain a common 29 bp sequence, called COM29. The dispersed repetitive sequence RPS1 may be involved in chromosomal rearrangements and may in part explain chromosome polymorphism in C. albicans. The origin of RPS1 was not determined., 1992年09月, 138, 1893, 1900, 研究論文(学術雑誌)
査読あり, 英語, JOURNAL OF GENERAL MICROBIOLOGY, CLONAL VARIATION OF CHROMOSOME SIZE DERIVED FROM THE RDNA CLUSTER REGION IN CANDIDA-ALBICANS, SI IWAGUCHI; M HOMMA; K TANAKA, Of the eight Candida albicans chromosomes, chromosome 2, assigned by the MGL1 probe, is more variable in size than the other chromosomes among strains. We found that the clonal variation of chromosome 2, which carries a rDNA gene, occurred at a frequency of up to 10% of the progeny clones. After total chromosomal digestion with XhoI, which has no recognition sites within the rDNA repeat unit, the fragments containing the rDNA cluster were detected by Southern hybridization. The difference in fragment sizes corresponded to the clonal size variation of chromosome 2. The intensity of hybridization with rDNA also correlated with the difference in size. In addition, there was no size change in the non-rDNA region as detected by NotI digestion of chromosome 2, and there was no observed change in the individual rDNA basic repeat unit size. From these lines of evidence, we confirmed that the clonal size variation of chromosome 2 which occurs at high frequency is derived from the size change of the rDNA cluster., 1992年06月, 138, 1177, 1184, 研究論文(学術雑誌)
査読あり, 英語, JOURNAL OF GENERAL MICROBIOLOGY, ELECTROPHORETIC KARYOTYPES OF CLINICALLY ISOLATED YEASTS OF CANDIDA-ALBICANS AND C-GLABRATA, K ASAKURA; SI IWAGUCHI; M HOMMA; T SUKAI; K HIGASHIDE; K TANAKA, One-hundred-and-four isolates of yeast were collected from the vaginas of 97 outpatients. The isolates were identified by their characteristics in a carbohydrate assimilation test, a serological test and from their morphology. Candida albicans and Candida glabrata were the major isolates (75% and 20%, respectively). The karyotypes of the isolates were analysed by pulsed-field gel electrophoresis and almost all the karyotypes were distinguishable from one another when the band mobilities were carefully compared. Characteristics and karyotypes were not directly correlated, but seven C. albicans isolates (from six patients) had a common atypical karyotype and shared the same phenotypic. These isolates are inferred to be generated by a wide genomic reorganization and mutation and the phenotypic changes may be advantageous for survival. The karyotypes of the isolates recovered from individual patients after intervals of 1-6 months were all identical except for one or two highly variable bands which were identified with an rDNA probe. This suggests that the variable bands are too variable to be useful for distinguishing strains, but from the patterns of the identical bands (i.e. except for the variable bands) we concluded that strains from individual patients do not change, at least over short periods. This, coupled with the extensive inter-isolate variability in karyotype, will be useful for Candida source determination and epidemiological studies., 1991年11月, 137, 2531, 2538, 研究論文(学術雑誌)
査読あり, 英語, JOURNAL OF GENERAL MICROBIOLOGY, VARIATION IN THE ELECTROPHORETIC KARYOTYPE ANALYZED BY THE ASSIGNMENT OF DNA PROBES IN CANDIDA-ALBICANS, S IWAGUCHI; M HOMMA; K TANAKA, By using pulsed-field gel electrophoresis, we have separated the entire chromosome bands and examined the electrophoretic karyotypes of 27 strains of Candida albicans. The electrophoretic karyotype varied widely among these strains. Their chromosomal DNAs were resolved into 7-12 bands ranging in size from 0.42 to 3.0 Mb. Most of the separated chromosomal bands were assigned by eight cloned C. albicans DNA probes. These results suggest that the haploid number of Ca. albicans chromosomes is eight. Each of the probes hybridized specifically to one or two bands of similar size in most strains. With the exception of the MGL1 probe, when two bands were detected by one probe, the size of one of them was very conserved whilst the other was of fairly variable size. The sizes of the chromosome bands assigned by the MGL1 probe were much more variable. As C. albicans is considered to be a diploid organism, it is inferred that the karyotype polymorphism between strains is mainly derived from wise size heterogeneity in one of the homologous chromosomes. Furthermore, we have confirmed species-specific and strain-specific variation in medically important Candida species (C. stellatoidea, C. tropicalis, C. parapsilosis, C. krusei, C. guilliermondii, C. kefyr and C. glabrata). Electrophoretic karyotype analysis is thus useful for species assignation. The TUB2 probe, encoding C. albicans beta-tubulin, hybridized to the chromosomal DNA of all the Candida species examined, but four C. albicans probes exhibited cross-species hybridization with C. stellatoidea only. The karyotype of C. stellatoidea seems to be within the range of the intraspecies variation observed in C. albicans., 1990年12月, 136, 2433, 2442, 研究論文(学術雑誌)
