Project description:Light is a universal environmental signal perceived by many organisms, including the fungi in which light regulates both common and unique biological processes depending on the species. We conducted a whole-genome microarray analysis on the basidiomycete fungus Cryptococcus neoformans to identify light-regulated genes.
Project description:Light is a universal environmental signal perceived by many organisms, including the fungi in which light regulates both common and unique biological processes depending on the species. We conducted a whole-genome microarray analysis on the basidiomycete fungus Cryptococcus neoformans to identify light-regulated genes. Two-condition experiment, cells grown in complete darkness or exposed to white light. Six biological replicates independently grown and harvested. One replicate per array.
Project description:To identify genes regulated by the homeodomain transcription factors Sxi1α and Sxi2a (Sex Inducer 1α and 2a) in Cryptococcus neoformans, we carried out a whole-genome expression experiment. We performed two independent whole-genome microarray experiments comparing transcript levels in cells that either possessed or were lacking the Sxi proteins. In the first experiment we compared the expression profile of a haploid sxi1αΔ strain to that of a haploid strain expressing both SXI1α and an inducible copy of SXI2a (Sxi +). In the second experiment, we compared the expression profile of a wild type cross (JEC20 x JEC21) to the expression profile of a cross whose mating partners did not possess either of the transcription factors (sxi2a∆ x sxi1α∆)(Sxi -). In both experiments RNA from each condition was harvested, labeled, and hybridized competitively to a spotted oligonucleotide microarray representing the approximately 6,500 genes in the C. neoformans genome. The resulting data was analyzed in Limma using standard methods.
Project description:We measured protein translation (by ribosome profiling) and RNA levels (by polyA-enriched RNA-seq) in Cryptococcus neoformans strain H99 and Cryptococcus neoformans strain JEC21. This is the first transcriptome-wide map of translation in this species complex.
