Exogenous calcium reduces postharvest loss of muskmelon fruit by promoting suberin polyaliphatic deposition.
BACKGROUND Ca2+ acts as a pivotal second messenger in plants, activating downstream signaling components that enhance resistance to both abiotic and biotic stresses. Suberin polyaliphatic (SPA) is a major component of the protective barriers in wounded fruit. However, it is unknown whether exogenous calcium treatment c...
