    Description: Sex determination in fungi is controlled by a small, specialized region of the genome in contrast to the large sex-specific chromosomes of animals and some plants. Different gene combinations reside at these mating-type (MAT) loci and confer sexual identity; invariably they encode homeodomain, alpha-box, or high mobility group (HMG)-domain transcription factors. So far, MAT loci have been characterized from a single monophyletic clade of fungi, the Dikarya (the ascomycetes and basidiomycetes), and the ancestral state and evolutionary history of these loci have remained a mystery. Mating in the basal members of the kingdom has been less well studied, and even their precise taxonomic inter-relationships are still obscure. Here we apply bioinformatic and genetic mapping to identify the sex-determining (sex) region in Phycomyces blakesleeanus (Zygomycota), which represents an early branch within the fungi. Each sex allele contains a single gene that encodes an HMG-domain protein, implicating the HMG-domain proteins as an earlier form of fungal MAT loci. Additionally, one allele also contains a copy of a unique, chromosome-specific repetitive element, suggesting a generalized mechanism for the earliest steps in the evolution of sex determination and sex chromosome structure in eukaryotes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Idnurm, Alexander -- Walton, Felicia J -- Floyd, Anna -- Heitman, Joseph -- England -- Nature. 2008 Jan 10;451(7175):193-6. doi: 10.1038/nature06453.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Genetics and Microbiology, Duke University Medical Center, Durham, North Carolina 27710, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18185588" target="_blank"〉PubMed〈/a〉

    Description: Candida species are the most common cause of opportunistic fungal infection worldwide. Here we report the genome sequences of six Candida species and compare these and related pathogens and non-pathogens. There are significant expansions of cell wall, secreted and transporter gene families in pathogenic species, suggesting adaptations associated with virulence. Large genomic tracts are homozygous in three diploid species, possibly resulting from recent recombination events. Surprisingly, key components of the mating and meiosis pathways are missing from several species. These include major differences at the mating-type loci (MTL); Lodderomyces elongisporus lacks MTL, and components of the a1/2 cell identity determinant were lost in other species, raising questions about how mating and cell types are controlled. Analysis of the CUG leucine-to-serine genetic-code change reveals that 99% of ancestral CUG codons were erased and new ones arose elsewhere. Lastly, we revise the Candida albicans gene catalogue, identifying many new genes.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2834264/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2834264/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Butler, Geraldine -- Rasmussen, Matthew D -- Lin, Michael F -- Santos, Manuel A S -- Sakthikumar, Sharadha -- Munro, Carol A -- Rheinbay, Esther -- Grabherr, Manfred -- Forche, Anja -- Reedy, Jennifer L -- Agrafioti, Ino -- Arnaud, Martha B -- Bates, Steven -- Brown, Alistair J P -- Brunke, Sascha -- Costanzo, Maria C -- Fitzpatrick, David A -- de Groot, Piet W J -- Harris, David -- Hoyer, Lois L -- Hube, Bernhard -- Klis, Frans M -- Kodira, Chinnappa -- Lennard, Nicola -- Logue, Mary E -- Martin, Ronny -- Neiman, Aaron M -- Nikolaou, Elissavet -- Quail, Michael A -- Quinn, Janet -- Santos, Maria C -- Schmitzberger, Florian F -- Sherlock, Gavin -- Shah, Prachi -- Silverstein, Kevin A T -- Skrzypek, Marek S -- Soll, David -- Staggs, Rodney -- Stansfield, Ian -- Stumpf, Michael P H -- Sudbery, Peter E -- Srikantha, Thyagarajan -- Zeng, Qiandong -- Berman, Judith -- Berriman, Matthew -- Heitman, Joseph -- Gow, Neil A R -- Lorenz, Michael C -- Birren, Bruce W -- Kellis, Manolis -- Cuomo, Christina A -- BB/F00513X/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/F013566/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- G0400284/Medical Research Council/United Kingdom -- HHSN266200400001C/AO/NIAID NIH HHS/ -- R01 AI050113/AI/NIAID NIH HHS/ -- R01 AI075096/AI/NIAID NIH HHS/ -- R01 DE015873/DE/NIDCR NIH HHS/ -- R01 HG004037/HG/NHGRI NIH HHS/ -- R01 HG004037-02/HG/NHGRI NIH HHS/ -- U54 HG003067/HG/NHGRI NIH HHS/ -- U54 HG003067-06/HG/NHGRI NIH HHS/ -- Wellcome Trust/United Kingdom -- England -- Nature. 2009 Jun 4;459(7247):657-62. doi: 10.1038/nature08064.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉UCD School of Biomolecular and Biomedical Science, Conway Institute, University College Dublin, Belfield, Dublin 4, Ireland. geraldine.butler@ucd.ie〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19465905" target="_blank"〉PubMed〈/a〉

    Description: Cryptococcus neoformans is a basidiomycetous yeast ubiquitous in the environment, a model for fungal pathogenesis, and an opportunistic human pathogen of global importance. We have sequenced its approximately 20-megabase genome, which contains approximately 6500 intron-rich gene structures and encodes a transcriptome abundant in alternatively spliced and antisense messages. The genome is rich in transposons, many of which cluster at candidate centromeric regions. The presence of these transposons may drive karyotype instability and phenotypic variation. C. neoformans encodes unique genes that may contribute to its unusual virulence properties, and comparison of two phenotypically distinct strains reveals variation in gene content in addition to sequence polymorphisms between the genomes.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3520129/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3520129/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Loftus, Brendan J -- Fung, Eula -- Roncaglia, Paola -- Rowley, Don -- Amedeo, Paolo -- Bruno, Dan -- Vamathevan, Jessica -- Miranda, Molly -- Anderson, Iain J -- Fraser, James A -- Allen, Jonathan E -- Bosdet, Ian E -- Brent, Michael R -- Chiu, Readman -- Doering, Tamara L -- Donlin, Maureen J -- D'Souza, Cletus A -- Fox, Deborah S -- Grinberg, Viktoriya -- Fu, Jianmin -- Fukushima, Marilyn -- Haas, Brian J -- Huang, James C -- Janbon, Guilhem -- Jones, Steven J M -- Koo, Hean L -- Krzywinski, Martin I -- Kwon-Chung, June K -- Lengeler, Klaus B -- Maiti, Rama -- Marra, Marco A -- Marra, Robert E -- Mathewson, Carrie A -- Mitchell, Thomas G -- Pertea, Mihaela -- Riggs, Florenta R -- Salzberg, Steven L -- Schein, Jacqueline E -- Shvartsbeyn, Alla -- Shin, Heesun -- Shumway, Martin -- Specht, Charles A -- Suh, Bernard B -- Tenney, Aaron -- Utterback, Terry R -- Wickes, Brian L -- Wortman, Jennifer R -- Wye, Natasja H -- Kronstad, James W -- Lodge, Jennifer K -- Heitman, Joseph -- Davis, Ronald W -- Fraser, Claire M -- Hyman, Richard W -- AI47087/AI/NIAID NIH HHS/ -- AI48594/AI/NIAID NIH HHS/ -- R01 AI050184/AI/NIAID NIH HHS/ -- R01 AI050184-05/AI/NIAID NIH HHS/ -- R01 HL088905/HL/NHLBI NIH HHS/ -- R01 HL088905-04A2/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 2005 Feb 25;307(5713):1321-4.
