Figure 4. Conidiation of WT, ΔEng18B and ΔEng18B+ T. atroviride strains in different nutrient regimes.

T. atroviride strains were inoculated on solid PDA, SMS, C limitation, N limitation, C+N limitation, N-acetylglucosamine (GlcNAc), chitin and glucose medium and incubated at 25°C in darkness for 7 days, with daily light exposures to induce conidiation. Conidial numbers were determined using a Bright-Line haemocytometer as per instruction of manufacturer. 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.
