In the phytopathogenic fungus Ustilago maydis, fusion of haploid cells is a prerequisite for infection. This process is controlled by a pheromone-receptor system. The receptors belong to the seven-transmembrane class that are coupled to heterotrimeric G proteins. Of four Galpha subunits in U. maydis, only gpa3 has a function during mating and cyclic AMP (cAMP) signaling. Activation of the cAMP cascade induces pheromone gene expression; however, it does not lead to the induction of conjugation tu ...[more]
