FIG. 3.

(A) MAT1-1 idiomorph showing coding and noncoding regions and directions of transcription of the three MAT genes. PCR and sequencing primers are indicated by half-arrows (Table 2). The two intergenic regions are arbitrarily designated A and B. (B) Single most-parsimonious midpoint rooted phylogram inferred from the MAT1-1 nucleotide sequence data. Note that strains representing six AFLP genotypes (AG1 to -6) of the clonal lineage are identical to one another and to outgroup strain NRRL 26370 (100% bootstrap support). The AB011379 MAT1-1 sequence was obtained from GenBank.
