Dynamic changes in proteins during apple (Malus x domestica) fruit ripening and storage.

ABSTRACT: A proteomic study, using two-dimensional polyacrylamide gel electrophoresis and matrix-assisted laser desorption/ionization time-of-flight/time-of-flight, was conducted in apple fruit (cv. 'Golden Delicious') starting at 10 days prior to harvest through 50 days in storage. Total protein was extracted using a phenol/sodium dodecyl sulfate protocol. More than 400 protein spots were detected in each gel and 55 differentially expressed proteins (p<0.05) were subjected to matrix-assisted laser desorption/ionization time-of-flight/time-of-flight analysis. Fifty-three of these proteins were finally identified using an apple expressed sequence tag database downloaded from Genome Database for Rosaceae and placed into six categories. The categories and the percentage of proteins placed in each categ
