Figure 6. Growth rate of WT, ΔEng18B and ΔEng18B+ T. atroviride strains in abiotic stress medium.

T. atroviride strains were inoculated on solid PDA plates supplemented with 1 M NaCl or 0.025% (w/v) SDS and incubated at 25°C in darkness. Growth rate was calculated from data recorded 7 days post inoculation. Error bars represent standard deviation based on three biological replicates. Different letters indicate statistical significance (P≤0.05) for strain differences within a single medium.
