A, effect of acid peptidase inhibitors on growth of T. emersonii. A mycelial plug was positioned in the center of an SDA plate and allowed to grow for 48 h. 100 nmol of antagonist was dried onto filter paper and placed at the growing edge. Plates were incubated for a further 18 h. B, hyphal extension in the presence of each antagonist was measured, and growth was calculated relative to methanol. C, dose response of fungal growth in the presence of TA1 (solid line) and PT1 (broken line).
