Fig. 1From: Deletion of the small GTPase rac1 in Trichoderma reesei provokes hyperbranching and impacts growth and cellulase productionColony morphology of T. reesei K1 and a representative Δrac1 strain on potato dextrose agar plate. A serial dilution of 104 to 102 spores of the reference strain K1 (a) and ∆rac1 (b) was applied on PDA plates containing 0.1% Triton X-100 and incubated for 72 h at 28 °CBack to article page
