(Submitter supplied) The capacity of the commensal yeast Candida albicans to grow in several forms, referred to as phenotypic plasticity, is critical for its survival, and abilities to thrive and cause infection in the human host. In this study, we report a novel phenotype of C. albicans, referred as the “gray” phenotype. The gray cell type, together with the previously discovered “white” and “opaque” cell types, forms a tristable phenotypic switching system. more...

(Submitter supplied) It has been proposed that the ancestral fungus was mating competent and homothallic. However, many mating competent fungi were initially classified as asexual because their mating capacity was hidden behind layers of regulation. For efficient in vitro mating, the essentially obligate diploid ascomycete pathogen C. albicans has to homozygose its mating type locus from MTLa/α to MTLa/a or MTLα/α, and then undergo an environmentally controlled epigenetic switch to the mating competent opaque form. more...

(Submitter supplied) The human commensal and opportunistic pathogen Candida albicans can switch between two distinct, heritable cell types, named “white” and “opaque,” which differ in morphology, mating abilities, metabolic preferences, and in their interactions with the host immune system. Previous studies revealed a highly interconnected group of transcriptional regulators that control switching between the two cell types. more...

(Submitter supplied) The human fungal pathogen Candida albicans can switch between two phenotypic cell types, termed “white” and “opaque.” Both cell types are heritable for many generations, and the switch between the two types occurs epigenetically, that is, without a change in the DNA sequence of the genome. In this work we describe that SSN6, the C. albicans functional homolog of Saccharomyces cerevisiae Cyc8, is a regulator of the white-opaque switch. more...

(Submitter supplied) As a successful commensal and pathogen of humans, Candida albicans encounters a wide range of environmental changes. Among them, ambient pH is an important factor, which changes frequently and affects many biological processes in this species. The ability to adapt to pH changes is tightly linked with pathogenesis and morphogenesis. In this study, we report that pH has a profound effect on white-opaque switching and sexual mating in C. more...

(Submitter supplied) The human pathogen Candida albicans can assume either of two distinct cell types, designated ‘‘white’’ and ‘‘opaque.’’ Each cell type is maintained for many generations; switching between them is rare and stochastic, and occurs without any known changes in the nucleotide sequence of the genome. The two cell types differ dramatically in cell shape, colony appearance, mating competence, and virulence properties. more...

(Submitter supplied) In this study, we report that glucose starvation and oxidative stress, common environmental stresses encountered by the pathogen, induce the development of mating projections and efficiently permit same-sex mating in C. albicans with an “a” mating type (MTLa/a).

(Submitter supplied) In Candida albicans, the a1-alpha2 complex represses white-opaque switching as well as mating. A ChIP-chip strategy was, therefore, used to screen for genes with a1-alpha2 binding sites and expression patterns consistent with a master switch gene (MSG). Of 51 genes identified with an a1-alpha2 binding site, one gene, TOS9, also referred to as EAP2, exhibited an expression pattern consistent with a MSG. more...

(Submitter supplied) Phenotypic plasticity, the ability to switch between different morphological types, plays critical roles in environmental adaptation, leading to infections, and allowing for sexual reproduction in pathogenic Candida species. Candida tropicalis, which is both an emerging human fungal pathogen and an environmental fungus, can switch between two heritable cell types termed white and opaque. In this study, we report the discovery of a novel phenotype in C. more...

(Submitter supplied) Modes of sexual reproduction in eukaryotic organisms are highly diversified. The human fungal pathogen Candida albicans undergoes a phenotypic switch from the white to the opaque phase in order to become mating-competent. In this study, we report that functionally and morphologically differentiated white and opaque cells show a coordinating behavior in the process of mating. Although white cells are mating-incompetent, they are induced to produce sexual pheromones when treated with opposite pheromones or interacted with opaque cells of an opposite mating type. more...

(Submitter supplied) The human fungal pathogen Candida albicans can switch between two cell types, “white” and “opaque,” each of which is heritable through many cell divisions. Switching between these two cell types is regulated by six transcriptional regulators which form a highly interconnected circuit with multiple feedback loops. Here, we identify a seventh regulator of white-opaque switching, which we have named Wor4. more...

(Submitter supplied) Candida albicans can stochastically switch between two phenotypes, white and opaque. Opaque cells are the sexually competent form of C. albicans and therefore undergo efficient polarized growth and mating in the presence of pheromone. In contrast, white cells cannot mate, but are induced - under a specialized set of conditions - to form biofilms in response to pheromone. In this work, we compare the genetic regulation of such "pheromone-stimulated" biofilms with that of "conventional" C. more...

(Submitter supplied) Among ~5,000,000 fungal species on Earth, Candida albicans is exceptional in its lifelong association with humans, where it exists either as a benign component of the gastrointestinal microbiome or as an invasive pathogen. Although it is generally assumed that invasiveness results from a breakdown of host immunity , it is also possible that specific fungal programs control the transition between these divergent lifestyles. more...

This dataset includes microarrays comparing expression levels in wild-type white and opaque cell types, as well as 6 different transcription factor deletion strains. All samples were hybridized against a common mixed reference to allow for comparison between any two datasets within this study.
