The dikaryon formation (mating) transcriptome of the basidomycete fungus Coprinopsis cinerea (Coprinus cinereus)

ABSTRACT: 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 Four biological replicate samples of each experimental strain were taken. Labelled cDNA was hybridized to arrays in a 2 channel reaction. The reference sample was an unmated monokaryotic strain.

The mushroom Coprinopsis cinerea is a classic experimental model for multicellular development in fungi because it grows on defined media, completes its life cycle in 2 weeks, produces some 10(8) synchronized meiocytes, and can be manipulated at all stages in development by mutation and transformation. The 37-megabase genome of C. cinerea was sequenced and assembled into 13 chromosomes. Meiotic recombination rates vary greatly along the chromosomes, and retrotransposons are absent in large regio  ...[more]
