cAMP Signaling in U. maydis
Description:
Ustilago maydis (U.maydis) belongs to the phyla Basidiomycetes (smut fungi) that infects maize. Dimorphism is linked to pathogenicity in U.maydis, where the budding haploid cells are saprobic in nature that converts to a dikaryotic filamentous pathogenic form after mating. cAMP signaling pathway regulates the dimorphic transition in U.maydis (Ref.1 and 2). Dimorphism process is regulated by two unlinked mating type loci, a and b. The a locus, a1 and a2, encodes a pheromone based precursors ...
