PALH — Fusarium graminearum PH-1

Summary

FgPALH (FGRAMPH1_01G18125) on chromosome 3 of Fusarium graminearum PH-1 encodes a PalH/RIM21 family protein that localises to the plasma membrane. The gene is associated with cellular responses to lithium ion, pH changes including neutral and basic pH, and filamentous growth in response to neutral pH. It is also linked to mycotoxin anabolism and homologous recombination. Studies of related genes in other species, including PalH homologues in Fusarium oxysporum and Verticillium dahliae, connect the family to pH signal transduction, though these associations are not yet established for FgPALH itself.
