Deletion of the small GTPase rac1 in Trichoderma reesei provokes hyperbranching and impacts growth and cellulase production

Table 1 Comparative image analysis with Image J of hyphal morphologies from T. reesei ∆rac1 strains compared to reference strain K1 during growth on lactose for 27 h, mean values and standard deviation are given

n = 25 per strain, samples of three different biological replicates were drawn from liquid cultures after 27 h, all values shown were tested with Student’s-t-test p < 0.05 and were all significantly different for K1 and ∆rac1 strains
