Abstract excerpt

The a mating type locus of Ustilago maydis contains the structural genes for a pheromone-based cell recognition system that governs fusion of haploid cells. The locus exists in two alleles, termed a1 and a2. We have completed the analysis of the nucleotide sequences unique to a1 and a2. Within th...
