Description
Summary:Banana ( Musa acuminata , cv Dwarf Cavendish) proteins were extracted from pulp tissue at different stages of ripening and analyzed by two-dimensional electrophoresis. The results provide evidence of differential protein accumulation during ripening. Two sets of polypeptides have been detected that increase substantially in ripe fruit. These polypeptides were characterized as glycoproteins by western blotting and concanavalin A binding assays. Antibodies againts tomato polygalacturonase cross-react with one of these sets of proteins.
