Project description:We used C. albicans diploid reference strain SC5314 to obtain aneuploid colonies via selection by drugs. We got a collection of aneuploid strains bearing trisomy of each homolog of each chromosome.
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:In Candida albicans, aneuploids are unstable. When grown on YPD-agar plates, aneuploids exhibit colony size variations. In this study, 6 aneuploid strains were spread on YPD-agar plates. The large colonies from each strain were sequenced. The small colonies were sequenced in another project.
Project description:Aneuploidy and the evolution of aneuploid karyotypes of Candida albicans strains was identified using aCGH. Whole chromosome and segmental aneuploidies, (specifically on the left arm of chromosome 5 - shown to be due to isochromosome formation) are associated with the appearance of resistance to the antifungal drug fluconazole. Keywords: Comparative Genomic Hybridization
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: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:Aneuploidy and the evolution of aneuploid karyotypes of Candida albicans strains was identified using aCGH. Whole chromosome and segmental aneuploidies, (specifically on the left arm of chromosome 5 - shown to be due to isochromosome formation) are associated with the appearance of resistance to the antifungal drug fluconazole. Keywords: Comparative Genomic Hybridization Hybridization of all strains was compared to the hybridization of SC5314, the sequenced laboratory 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:The purpose of this review is to describe the tools used to detect genome changes, to highlight recent advances in our understanding of large scale chromosome changes that arise in C. albicans and to discuss the role of specific stresses in eliciting these genome changes. The types of genomic diversity that have been characterized suggest C. albicans can undergo extreme genomic changes in order to survive stresses in the human host. We propose that C. albicans and other pathogens may have evolved mechanisms not only to tolerate, but also to generate, large-scale genetic variation as a means of adaptation. Strains included in this series are described in a Eukaryotic Cell review of genomic plasticity of Candida albicans. These strains are well-characterized and some of them are frequently utilized by the Candida community to generate mutant strains. Each strain was analyzed once and all strains were competed against the same reference strain, SC5314 (the first sequenced C. albicans strain).
