(Submitter supplied) We use ChIP-seq to identify the targets of Efg1 in Candida parapsilosis. We show that Efg1 binds to 502 promoter regions, including 70 potential transcription factors or regulatory proteins. Several of the transcription factors belong to networks that regulate biofilm development and white-opaque switching in C. albicans. Efg1 also binds to its own promoter. The binding site for C. parapsilosis Efg1 resembles that of orthologs in other fungi. more...

(Submitter supplied) In Candida albicans the Efg1 transcription factor (a member of the APSES family) is an important regulator of hyphal growth, and of the white-to-opaque transition. In contrast, we show that the Efg1 ortholog in Candida parapsilosis is a major regulator of a different morphological switch at the colony level, from a concentric to smooth morphology. The rate of switching is at least 100-fold increased in an efg1 knockout relative to wild type. 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) Biofilm development by Candida albicans requires cell adhesion for the initial establishment of the biofilm and the continued stability after hyphal development occurs; however, the regulation of the process has not been fully established. Using chromatin immunoprecipitation coupled to microarray analysis (ChIP-chip) we have characterized a regulon containing the Mcm1p factor that is required for the initial surface adhesion during biofilm formation. more...

(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) The goals of this study were to identify the Efg1p-regulon during GI tract colonization and to compare C. albicans gene expression during colonization of different organs of the GI tract. Our results identified significant differences in gene expression between cells colonizing the cecum and ileum. In addition, during laboratory growth, efg1- null mutant cells grew to a higher density than WT cells. more...

(Submitter supplied) Candida albicans is an opportunistic fungal pathogen that can infect oral mucosal surfaces despite being under continuous flow from saliva. Previous studies have shown that under specific conditions C. albicans will form microcolonies that more closely resemble the biofilms formed in vivo than standard in vitro biofilm models. However, very little is known about these microcolonies, particularly genomic differences between these specialized biofilm structures and the traditional in vitro biofilms. more...

(Submitter supplied) C. albicans is a dimorphic yeast which can switch from budding yeast and to hyphal forms and this property is essential for biofilm establishment and maturation. C. albicans undergoes this yeast-to-hyphal switch in response to high CO2. The purpose of this study is to use RNA-seq to investigate pathways whose genes are differentially expressed when C. albicans biofilms are grown in a physiologically relevant elevated (5%) CO2 environment compared to a low/atmospheric (0.03%) CO2 environment. more...

(Submitter supplied) To elucidate the impact of IFU5 in Candida albicans, genome wide transcription profiling was performed in ifu5?/? mutant strain. Wild type and mutant cells were grown for 5 hours and RNA extracted from these cultures, followed by microarray profiling. Expression of six genes (EFG1, ALS3, SOD3, BMT4, COX2, NAD1) was validated by qPCR.

(Submitter supplied) The fungus Candida albicans is part of the human microbiome and mainly colonises the GI tract of healthy individuals. However, when the balance in the GI tract is disturbed, the fungus can switch from a commensal to a virulent lifestyle and can turn into a life-threatening pathogen. Life in the host is characterised by a constant struggle for nutrients, essential trace elements such as iron, copper and zinc are particularly important. more...

(Submitter supplied) The dataset contains ChIP-Seq data of the Set3 and Hos2 proteins in Candida albicans, assayed in two morphological phases (yeast and hypha). The Set3 and Hos2 proteins in the respective strains carry 9myc epitopes and ChIP was performed with an anti-myc antibody. Included samples are the following: 1 input and 1 ChIP sample of an untagged wild type strain as negative control assayed in the yeast phase, 1 input and 3 ChIP biological replicates of the Set3-9myc strain in the yeast phase, 1 input and 2 ChIP biological replicates of the Set3-9myc strain in the hypha phase, 1 input and 2 ChIP biological replicates of the Hos2-9myc strain in the yeast phase, 1 input and 2 ChIP biological replicates of the Hos2-9myc strain in the hypha phase, 1 input and 3 ChIP biological replicates of Set3-9myc in a set1delta/delta background in the yeast phase.

(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) To understand the biological relevance of the role played by the HHT1 histone H3 variant in C. albicans, we performed a transcriptome analysis of the mutant by global gene expression array analysis. We analyzed gene expression profile of the mutant in strains LR107 and LR108 (hht1∆/hht1∆) and the parent wild type (SC5314) strain grown in YPD liquid medium at 30°C. In the microarray analysis, a total of 1222 genes were found to be expressed significantly different (fold change < 1.5 at p-value < 0.05) between wild type and two hht1 null mutants. more...

(Submitter supplied) Abstract: Candida parapsilosis and Candida albicans are human fungal pathogens that belong to the CUG clade in the Saccharomycotina. In contrast to C. albicans, relatively little is known about the virulence properties of C. parapsilosis, a pathogen particularly associated with infections of premature neonates. We describe here the construction of >200 C. parapsilosis strains carrying double allele deletions of transcription factors, protein kinases and species-specific genes. more...
