Conservation of the b mating-type gene complex among bipolar and tetrapolar smut fungi.

The Plant cell - 1 Jan 1993

Bakkeren G, Kronstad J W

Abstract excerpt

In the phytopathogenic fungus Ustilago hordei, one locus with two alternate alleles, MAT-1 and MAT-2, controls mating and the establishment of the infectious dikaryon (bipolar mating). In contrast, for U. maydis, these functions are associated with two different gene complexes, called a and b (te...
