Structure and site of the mutation in the <i>PcCesA3</i> gene associated with pyrimorph resistance.

<p>(A) Intron/exon structure of the <i>PcCesA3</i> gene. Numbers represent the size in base pairs. Point mutations in pyrimorph-resistant mutants (RF>50) and the predicted amino acid substitution in the mutant gene products are indicated. (B) Alignment of partial amino acid sequences of CesA3 in <i>P. capsici</i> (PcCesA3). Hd3, Hd11, Hx18, and Dz21 are wild-type isolates. R3-2, R3-3, and R11-1 are pyrimorph-resistant mutants. Mutations in pyrimorph-resistant mutants of <i>P. capsici</i> are indicated by asterisks.
