Aflatoxin production and maximum stress tolerance of H2O2 (mM) were previously determined in Fountain et al.32. Significant DEGs were identified using Cuffdiff by comparing oxidative stress treatments within each medium with α = 0.05. *Previously observed aflatoxin production and H2O2 tolerance in Fountain et al.32. Toxin Production: ‘+++’ High Aflatoxin Producer; ‘+’ Moderate Aflatoxin Producer; ‘‒‒‒’ Atoxigenic Biological Control Isolate; ‘−’ Atoxigenic Isolate.
