FIG. 9.

A model of the MTL loci in the four classes of C. glabrata strains. The three MTL loci were distinguished as XbaI fragments A, B, and C in Southern analyses (see Fig. 5). The genotypes of the loci in the different classes were interpreted from the combined results of Southern, PCR, and sequencing data. The strains are distinguished as αaa (class I), ααa (classes II and III), or ααα (class IV). A hypothesized class V is aaa. The expression patterns are distinguished as either a expression or α expression, as determined by Northern analysis.
