Fig. 9

Mechanistic model for decreasing intercellular pH by deleting the H+-ATPase gene tre76238, thus enhancing cellulase production in T. reesei. Deleting tre76238 impairs the ability of protons to be transported out of cells. Intracellular acid accumulation promotes a cytosolic Ca2+ burst that activates calcium signaling. The effects of adding LaCl3 suggest that Ca2+ channels are essential for cellulase production in Δ76238, using glucose as a repressive carbon source. Solid arrows indicate the data supported by our own experiments
