Arabinogalactan proteins (AGPs) and pectins in apple fruits during postharvest storage

Changes in the arrangement of cell wall components determine cell wall properties (integrity, stiffness), thereby affecting the macro properties of fruits, which are important for consumers and industry. The immunocytochemical study was conducted to elucidate the distribution of arabinogalactan proteins (AGPs) and pectic polysaccharides contained in apple (Malus x domestica) fruits during senescence process.

Apple and cells

Microscopy observations showed spatio-temporal changes in the localization and dependencies between all examined constituents. Leszczuk et al. propose that AGPs are involved in establishment of the cell wall – plasma membrane continuum.
