Mechanism of CmbZIP11 regulates CmPMT1 and CmPMT15 expression to regulate methyl-esterification of HG affecting fruit softening in melon. CmbZIP11 through activates the expression of CmPMT1 and CmPMT15 to regulate the degree of methyl-esterification of HG thereby adjust the amount of HG-Ca2+ cross-linked ‘Egg-box’ matrix, leading to different accessibility for PMEs, PGs and PLs for HG degradation and fruit softening. HG: Homogalacturonan; D-GalA: D-Galacturonic acid; GAUTs: Galacturonosyltransferases; GoSAMT: Golgi SAM transporter; PMT: Pectin methyltransferase; PAT: Pectin acetyltransferase; PME: Pectin methylesterase; PG: Polygalacturonase; PL: Pectate lyase.
