HOG1 — Fusarium culmorum CS7071

Summary

FCUL_11373.1, symbol HOG1, on chromosome 4 of Fusarium culmorum, encodes a protein with ERK1, protein serine kinase activity, protein serine/threonine kinase activity, and ATP binding. This gene is associated with stress responses, including osmolarity sensing, redox sensing, and responses to cold, caffeine, curcumin, methylglyoxal, and cesium. It is linked to regulation of lipid storage, spore dispersal, differential growth, arsenite transport, polyprenol and dolichol metabolism, thiamin metabolism, PKC activation, and the SAPK signaling pathway. The encoded protein localizes to the cytoplasm and nucleus. Associations with respiration rate and oxidative stress have also been noted. Studies of related genes in other species link the Hog1 family to traits such as drought tolerance, biomass yield, potassium content and uptake, turgor pressure, and glucose content, as well as to reduced virulence.
