(Submitter supplied) The Poly(A)-Tail focused RNA-seq, or PAT-seq approach, is an affordable and efficient tool for the measure of 3’UTR dynamics. We show here that PAT-seq returns (i) digital gene expression, (ii) polyadenylation site usage within and between samples, including alternative adenylation, and (iii) the polyadenylation-state the transcriptome. PAT-seq differs from previous 3’ focused RNA-seq methods in that it strictly depends on native 3’ adenylation within total RNA samples and thus removes the need for ribosome depletion and, that the full native poly(A)-tail is included in the sequencing libraries. more...

(Submitter supplied) The cell wall is essential for viability of fungi and is an effective drug target in pathogens such as Candida albicans. The contribution of posttranscriptional gene regulators to cell wall integrity in C. albicans is unknown. We show that the C. albicans Ccr4-Pop2 mRNA deadenylase, a regulator of mRNA stability and translation, is required for cell wall integrity. The ccr4/pop2 mutants display reduced wall β-glucans and sensitivity to the echinocandin caspofungin. more...

(Submitter supplied) The Ccr4-Not complex is a major regulator of stress responses that controls gene expression at multiple levels, from transcription to mRNA decay. Ccr4, a core subunit of the complex, is the main cytoplasmic deadenylase in Saccharomyces cerevisiae, however its mRNA targets have not been mapped on a genome-wide scale. Here we describe a genome-wide approach, RNA immunoprecipitation-high throughput sequencing (RIP-seq), to identify the RNAs bound to Ccr4, and two proteins that associate with it, Dhh1 and Puf5. more...

(Submitter supplied) Poly(A)-ClickSeq is a new methodology for the sequencing of the 3'UTR/poly(A) tail junction of RNA. We analysed both wild-type and CF25Im knock-down HeLa cells in culture using Poly(A)-ClickSeq to find the distribution of poly(A) sites in these samples and determine the role of CF25Im in poly(A) site selection (alternative poly-adenylation, APA).

(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) 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) 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) Biofilm formation on medically implanted devices by Candida albicans poses a significant clinical challenge. Here we compared biofilm-associated gene expression in two clinical C. albicans isolates, SC5314 and WO-1, to identify shared gene regulatory responses that may be functionally relevant. Among the 50 genes most highly expressed in biofilms relative to planktonic (suspension-grown) cells, we were able to recover insertion mutations in 25 genes. more...

We analysed the gene expression profiles of YPK102/1 and YPK102/2 and the parent wild type (SC5314) strain grown in YPD liquid medium at 30°C till the start of the stationary phase. In the microarray analysis, a total of 607 genes were found to be differentially expressed (fold change < 1.5 at p-value < 0.05) between the wild type and two zcf32 null mutants. more...

(Submitter supplied) Biofilm formation is an important virulence trait of the pathogenic yeast Candida albicans. We have combined gene overexpression, strain barcoding and microarray profiling to screen a library of 531 C. albicans conditional overexpression strains (~10% of the genome) for genes affecting biofilm development in mixed-population experiments. The overexpression of 16 genes increased strain occupancy within a multi-strain biofilm, whereas overexpression of 4 genes decreased it. 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) Alternative polyadenylation (APA) of mRNAs has emerged as an important mechanism for post-transcriptional gene regulation in higher eukaryotes. Although microarrays have recently been used to characterize APA globally, they have a number of serious limitations that prevents comprehensive and highly quantitative analysis. To better characterize APA and its regulation, we have developed a deep sequencing-based method called Poly(A) Site Sequencing (PAS-Seq) for quantitatively profiling RNA polyadenylation at the transcriptome level. more...

(Submitter supplied) The use of alternative polyadenylation sites is common and affects the post-transcriptional fate of mRNA, including its stability, localization, and translation. Here we present a method for genome-wide and strand-specific mapping of poly(A) sites and quantification of RNA levels at unprecedented efficiency by using an on-cluster dark T-fill procedure on the Illumina sequencing platform. Our method outperforms former protocols in quality and throughput, and reveals new insights into polyadenylation in Saccharomyces cerevisiae.
