Model of turgor pressure generation involving fatty acids, glycogen, glycerol and triacylglycerols in M. oryzae. Pathway (1) is where glycogen is carried into the glycolysis pathway to produced pyruvate, which then enters Krebs cycle for energy production for penetration of fungus into host [25]. Pathway (2) involves lipid bodies moving into the appressorium during maturation, where they are degraded by triacylglycerol lipase during turgor generation [26]. Pathway (3) explains the glycoxylate cycle that produces glycerol. Pathway (4) involves the fatty acid synthesis at the top of the route and ends with fatty acid degradation for turgor pressure of the appressorium [23].
