Project description:In Candida parapsilosis, transcriptomes of two aneuploid adaptors, TJ60 and TJ74, were compared to the euploid parent #12108. Cells were grown in YPD broth at 37C from OD600=0.1 to 1.0. Cells were collected and RNA was extracted.
Project description:We obtained ketoconazole tolerant mutants in Candida albicans after exposing the strain SC5314 to inhibitory concentration of ketoconazole. We did RNA-Seq to compare the transcriptomes of the aneuploid strains versus the parent euploid strain.
Project description:Several aneuploid Candida glabrata strains, each bearing a unique karyotype, were spread on YPD plates. They all exhibited colony size vairations. Randmly 10 large colonies from each strain were sequenced.
Project description:Candida albicans lab strain SC5314 was used as parent to obtain tebuconazole adaptors. Two adaptors, TJ1503 and TJ1669 were aneuploid. Transcriptomes of these two strains were compared to SC5314.
Project description: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. Two independent deletions were constructed for each target gene. Growth in > 40 conditions was tested, including carbon source, temperature, and the presence of antifungal drugs. The phenotypes were compared to C. albicans strains with deletions of orthologous transcription factors. We found that many phenotypes are shared between the two species, such as the role of Upc2 as a regulator of azole resistance. Others are unique. For example, Cph2 plays a role in the hypoxic response in C. parapsilosis and not in C. albicans. We found extensive divergence between the biofilm regulators of the two species. We identified 7 transcription factors and one protein kinase that are required for biofilm development in C. parapsilosis. Only three (Efg1, Bcr1, and Ace2) have similar effects on C. albicans biofilms, whereas Cph2, Czf1, Gzf3 and Ume6 have major roles in C. parapsilosis only. In addition, two transcription factors (Brg1 and Tec1) with well-characterized roles in biofilm formation in C. albicans do not have the same function in C. parapsilosis. We also compared the transcription profile of C. parapsilosis and C. albicans biofilms. Our analysis suggests the processes shared between the two species are predominantly metabolic.
Project description:Candida albicans lab strain SC5314, which is a euploid diploid, was used to generate aneuploid fluconazole adaptors. Transcriptomes of aneuploids were compared to the euploid parent by growing cells in rich YPD broth.
Project description:Investigation of the role of HAC1 using transcriptional profiling of Candida parapsilosis treated with 5 mM dithiothreitol Gene expression of wild type and hac1 deletion strains were compared during growth in YPD only and growth in YPD with 5 mM DTT
