bZIP transcription factor AflHapX coordinates iron homeostasis and aflatoxin biosynthesis in Aspergillus flavus

AflHapX is critical for A. flavus's adaptive response to iron excess and starvation, influencing aflatoxin B1 production. The transcription factor regulates genes involved in iron homeostasis, aflatoxin biosynthesis, and oxidative stress responses.
