FIG 3 .

Vegetative and stress-related growth defects of Δpp2Ac1 and Δpp2Ac1 Δpro22 mutant strains. (A) Vegetative growth on SWG medium was investigated in race tubes for 6 days, and growth fronts were marked every 24 h. (B) Cell wall stress- and osmotic stress-related growth was tested on SWG medium containing 250 µg/ml CFW (dark gray) or 0.6 M glucose (light gray). All error bars indicate standard deviations from three independent experiments with three replicates each. All brackets indicate significant differences in growth according to Student’s t test with P < 0.01 (*) for single and double deletion strains. wt, wild type.
