Transcription factor that is involved in the formation of the two Fusaric acid derivatives, dehydrofusaric acid and fusarinolic acid, serving as a detoxification mechanism (PubMed:26662839). Expression is up-regulated upon exogenous application of fusaric acid (PubMed:26662839). Fusaric acid is phytotoxic to plants such as cotton and banana (PubMed:20955724, PubMed:23922960). It has been shown to induce programmed cell death in plants (PubMed:16868776, PubMed:23838885). In addition to a mild toxicity to animals, fusaric acid exhibits acanthamoebicidal, antioomycete, and antimycobacterial activities (PubMed:17927749, PubMed:22864988, PubMed:21811925).
