Plasma membrane physicochemical changes during maturation and postharvest storage of muskmelon fruit.

Summary

As muskmelon fruit progress from immaturity to maturity, and with storage of mature fruit at 4 or 24 deg C, increased permeability of the hypodermal-mesocarp tissue occurs coincident with an increase in the saturation index of the plasma membrane phospholipids. Buoyant density of the plasma membrane from hypodermal mesocarp tissue increased from 1.13 to 1.14 g/cm3 during fruit maturation. Vanadate-sensitive ATPase activity was highest in mature fruit at harvest. After 10 days of storage, vanadate-sensitive ATPase activity was much lower in fruit kept at 24 deg C than in those kept at 4 deg C. This was correlated with increased hypodermal-mesocarp membrane permeability. The authors suggest that biochemical changes affecting the lipid matrix of the plasma membrane influence fruit membrane permeability and possibly muskmelon storage life.
