(A) Growth inhibition rate. 5-mm mycelial blocks of M. oryzae strains were inoculated on CM medium and medium with stress conditions for 8 days, and the diameter of colonies was then measured to calculate the growth inhibition rate. The experimental strains were the wild-type strain, mutants (ΔMonit4, Δgpf1, Δgcc1, Δtas1 and Δgta1), and complemented strains (Monit4-c, gpf1-c, gcc1-c, tas1-c and gta1-c). Same capital letters in same stress item indicate non-significant difference estimated by Duncan's test (P≤0.05). (B) Mycelial growth of ΔMonit4 on MM medium. The wild-type strain, ΔMonit4, and complemented strain Monit4-c were grown on MM medium at 25°C for 8 days. Bar = 5 mm.
