ABCA — Fusarium graminearum PH-1

Summary

FgABCA (FGRAMPH1_01G24685) on chromosome 4 of Fusarium graminearum encodes an ABC transporter of the PDR/CDR subfamily, possessing ATP hydrolase activity and ATP-coupled transmembrane transporter activity. The gene is associated with xenobiotic detoxification via export across the plasma membrane, response to antibiotics, toxin anabolism, and extracellular transport. It is linked to seed germination, hypersensitivity, DNA repair, and sporulation rate, cell death, and nutrient uptake. Localisation evidence places the product at the plasmalemma. Studies of related genes in other species connect the family to multidrug resistance, oxidative stress response, and traits such as plant height, root length, and drought tolerance, though these associations are not yet established for FgABCA itself.
