Description
Plant-pathogenic fungi store fat in lipid droplets inside their spores and threads, and they burn that fat to power infection. The nine authors study a plasma membrane proton pump, CsPMA2, in the fungus Colletotrichum siamense. Deleting the pump gene shrank spores, cut germination, and weakened both the infection pads the fungus builds on leaves and its overall virulence, while thread growth stayed normal.
The mutant also grew more sensitive to phytic and oxalic acids. The pump sits in lipids of the plasma and inner membranes, and without it droplet accumulation fell sharply, with twelve lipid species down and three up. Low pH also suppressed the pump and droplet buildup. The authors conclude the pump governs droplet formation and thereby the fungus's power to infect.
