Transcriptome analysis of a Sordaria macrospora nox1 mutant

ABSTRACT: The Sordaria macrospora nox1 mutant has a block in sexual development at the stage of protoperithecia formation, and therefore is sterile. The aim of this study was to determine the transcriptome of microdissected protoperithecia from the mutant, as well as the transcriptomes of total RNA from the mutant and the wild type for comparison. The data were then compared with transcriptome data from protoperithecia of the wild type and the developemental mutant pro1; the corresponding data were generated in a previous study (Teichert et al. 2012, BMC Genomics 13: 511, GEO accession GSE33668). The samples (amplified RNA from nox1 microdissected protoperithecia and total RNA from nox1 and wild type mycelia undergoing sexual development) were sequenced as paired-end reads on an Illumina HiSeq 2000, two independent biological replicates for each nox1 sample and one replicate for the wild type.

NADPH oxidase (NOX)-derived reactive oxygen species (ROS) act as signaling determinants that induce different cellular processes. To characterize NOX function during fungal development, we utilized the genetically tractable ascomycete Sordaria macrospora. Genome sequencing of a sterile mutant led us to identify the NADPH oxidase encoding nox1 as a gene required for fruiting body formation, regular hyphal growth, and hyphal fusion. These phenotypes are shared by nor1, lacking the NOX regulator NO ...[more]

The genome and development-dependent transcriptomes of Pyronema confluens: a window into fungal evolution

Project description:This transcriptome analysis accompanies the genome sequencing of Pyronema confluens for purposes of annotation and gene expression quantification. P. confluens is a basal filamentous ascomycete that forms primitive fruiting bodies (apothecia) to generate its sexual spores. We have performed RNA-seq for two growth conditions allowing only vegetative growth and one condition allowing sexual development to identify genes that are differentially regulated during fruiting body formation. The samples sex (sexual development), DD (growth in darkness, no sexual development), and vegmix (pool of several conditions, no sexual development) were sequenced as paired-end reads on an Illumina HiSeq 2000, two independent biological replicates for each sample, two technical replicates for each biological replicate (each library was sequenced twice in two independent flow cells).

Combining laser microdissection and RNA-seq to chart the transcriptional landscape of fungal development

Project description:RNA-seq analysis of developmental stages from the filamenous ascomycete Sordaria macrospora. Using laser capture microdissection, we separated protoperithecia (young fruiting bodies) from the surrounding hyphae. RNA isolation and amplification from 150 protoperithecia yields enough material for RNA-seq analysis. The resulting data were compared to RNA-seq data from whole mycelial exctracts (total vegetative and total sexual mycelium) to characterize the genome-wide spatial distribution of gene expression during sexual development. We analyzed total vegetative mycelium, total sexual mycelium, and protoperithecia from the wild type as well as protoperithecia from the sterile mutant pro1. Additionally, we used the RNA-seq information to improve the predicted S. macrospora gene models, and annotated UTRs for more than 50 % of the genes.

Gene expression in a wild type strain (FGSC 2489) versus an Dime-2 strain (FGSC 17937) in Neurospora crassa during nitrogen starvation

Project description:The protein kinase Ime2 is known to have an important role in meiosis in the yeast Saccharomyces cerevisiae. However, the Neurospora crassa IME2 homolog functions in self/nonself recognition as well as in the development of fungal sexual structures called protoperithecia. In N. crassa, protoperithecia are induced upon nitrogen starvation. We were interested in gene expression differences between an ime-2 deletion strain and a wild type strain, and due to the role of ime-2 during sexual development, carried out these arrays on media that was lacking in nitrogen.

Murine pulmonary arterial smooth muscle cells: Wild-type vs. NOX1 deficiency (miRNA profiling)

Project description:NOX1 is a catalytic subunit of nonphagocytic NADPH oxidase, mainly localized to smooth muscle cells in the vasculature. We investigated the pathology underlying the pulmonary arterial hypertension-like phenotype demonstrated in mice deficient in the Nox1 gene (Nox1-KO). Spontaneous enlargement and hypertrophy of the right ventricle, accompanied by hypertrophy of pulmonary vessels, were demonstrated in Nox1-KO at 9-18 weeks of age. Since an increased number of α-smooth muscle actin-positive vessels was observed in Nox1-KO, pulmonary arterial smooth muscle cells (PASMCs) were isolated and characterized by flow cytometry and TUNEL staining. In Nox1-/Y PASMC, the number of apoptotic cells was significantly reduced without any change in the expression of endothelin-1, and hypoxia-inducible factors HIF-1a and HIF-2a, factors implicated in the pathogenesis of PAH. microRNA expression profiling of mouse pulmonary arterial smooth muscle cells in wild-type and NOX1-KO was analyzed.

Proteomic analysis in transgenic hybrid aspen (Populus tremula x tremuloides) trees overexpression of vesicle-associated membrane protein PttVAP27-17

Project description:In this study we report on transgenic hybrid aspen (Populus tremula x P. tremuloides) lines that showed potential to increase biomass production both in the greenhouse and after five years of growth in the field. The transgenic lines carried an overexpression construct for Populus tremula x tremuloides vesicle-associated membrane protein (VAMP)-associated protein PttVAP27-17 (Potri.019G116400) that was selected from a gene-mining program for novel regulators of wood formation. A proteomic analysis was performed to characterize the overall effect of the overexpression of PttVAP27-17 on plant metabolic pathways. 20 mg of xylem sample for the selected wild type (WT) and three transgenic lines (lines 1,2 and 3) was collected in the following manner from two-months-old, greenhouse grown trees: The frozen bottom-part of the stem (10-17 cm portion from the base of the stem) was peeled, and the surface of the secondary xylem consisting of living vessels and fibers (into the depth of approximately one mm from the surface) was scraped. The xylem scrapings were ground to fine powder in liquid nitrogen and stored at -80oC. The analyses included 3-5 biological replicates for each of the transgenic lines, and seven replicates for the wild type.
