Project description: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. keywords: Cell type comparison
Project description: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). To examine a comprehensive timecourse of meiosis in this organism, we took samples over a 15-hour period, 3 hours apart: K-3, K, K+3, K+6, K+9, K+12. Keywords: time course

Keywords: time course Four biological replicate samples of each timepoint were taken. Labelled cDNA was hybridized to arrays in a 2 channel reaction. The reference sample was a mixture of timepoint samples.
