Aspergillus flavus is an efficient producer of mycotoxins, particularly aflatoxin B1, probably the most hepatocarcinogenic naturally-occurring compound.Although the we care vitamin a and d ointment inducing agents of toxin synthesis are not unanimously identified, there is evidence that oxidative stress is one of the main actors in play.In our study, we use menadione, a quinone extensively implemented in studies on ROS response in animal cells, for causing stress to A.flavus.For uncovering the molecular determinants that drive A.
flavus in challenging oxidative stress conditions, we have evaluated a wide spectrum of several different parameters, ranging from metabolic (ROS and rectangular barn quilt patterns oxylipin profile) to transcriptional analysis (RNA-seq).There emerges a scenario in which A.flavus activates several metabolic processes under oxidative stress conditions for limiting the ROS-associated detrimental effects, as well as for triggering adaptive and escape strategies.
