(Submitter supplied) Meiosis was compared in rad50-1 and wild type strains of C. cinerea at 6 time points spanning the meiotic timecourse. Abstract: The basidiomycete Coprinopsis cinerea is well-suited to studies of meiosis because meiosis progresses synchronously in ten million cells within each mushroom cap. Approximately 20% of C. cinerea genes exhibit changing expression during meiosis, but meiosis and mushroom development happen concurrently so differentially expressed genes might not be directly involved in meiotic processes. more...

(Submitter supplied) Coprinopsis cinerea exhibits synchronised meiosis in the gill tissue of the fungus, which is 75% meiotic. The mushroom develops from a dikaryon, which contains two separate nuclei. These nucleifuse in the basidia (karyogamy). After karyogamy, the nuclei enter an extended meiotic prophase, in which pahcytene occurs at 6 hours post karyogamy (K+6). The tetrads produced by the second meiotic division are present 12 hours after karyogamy (K+12). more...

(Submitter supplied) Mating compatibility in C. cinerea is controlled by two loci, A and B. Following fusion of undifferentiated hyphal cells, a complex program is initiated which results in the maintenance of one nucleus from each parent in every cell (the dikaryon). We identified downstream targets of the A locus (A on), the B locus (B on), and both loci (Aon Bon) using strains in which the two pathways are activated separately, and a dikaryotic strain. more...

(Submitter supplied) Large scale assessment of the transcriptomes of the vegetative mycelium and primordium will facilitate the generation of a more comprehensive picture of the fruiting process in basidiomycetes. We coupled 5'-Serial Analysis of Gene Expression (5'-SAGE) to high-throughput pyrosequencing from 454 Life Sciences to analyze the transcriptomes and identify up-regulated genes (URGs) among vegetative mycelium (Myc) and stage 1 primordium (S1-Pri) of Coprinopsis cinerea during fruiting body development. more...

(Submitter supplied) This study compared the transcriptomes of maize anthers at both 1mm and 1.5mm lengths from male sterile mutants with either the am1-489 or am1-pra alleles as well as from fertile siblings of the mutant plants. Comparisons were done varying just the stage (1mm vs 1.5 mm), just the allele (am1-pra vs am1-489 at the same stage), and wild-type vs mutant (same stage and allele). Genes were categorized as On (expressed) or Off (not detected) and if both channels produced an intensity, the differential expression was determined. more...

(Submitter supplied) Mre11, together with Rad50 and Xrs2/NBS, plays pivotal roles in homologous recombination, repair of DNA double strand breaks (DSBs), activation of damage-induced checkpoint, and telomere maintenance. Using DNA microarray assays to analyze yeast mutants (mre11delta, rad50delta, and spo11Y135F) defective for meiotic DSB formation, we demonstrate that the absence of Mre11 in yeast causes specific effects on regulation of a class of meiotic genes for spore development. more...

Analysis of Mre11 deficient cells at meiotic prophase during sporulation. Mre11 is important in homologous recombination, repair of DNA double strand breaks, activation of damage-induced checkpoint, and telomere maintenance. Results provide insight into the role of Mre11 in spore development.
