AQY1 — Fusarium graminearum PH-1

Summary

FGRAMPH1_01G02029 (AQY1, FgAQP1) in Fusarium graminearum PH-1 encodes an aquaporin, a water channel protein with an aquaporin-transporter and MIP domain. The gene is associated with water channel activity and localizes to the nuclear membrane and plasmalemma. It is linked to perithecium formation, asexual reproduction, secondary metabolism, and autophagy. Phenotypic associations include altered growth rates, decreased sporulation, abnormal lipid particle morphology, reduced desiccation and hyperosmotic stress resistance, increased chronological lifespan, and decreased replicative lifespan. The gene is also associated with freeze-thaw resistance, altered fermentative metabolism, and cell cycle progression in G1 phase. Related genes in other species link the family to oxidative stress response and increased sporulation efficiency.
