Abstract: Proteomics is one of the research focuses in post\|genomics era. In this article， the proteome researches of fruit trees were reviewed， including the optimization of
two\|dimensional electrophoresis system and its application in the fruit trees growth and development， stress responses， hormone response and postharvest processing. At last， the application prospect of proteome research in fruit trees was discussed.

Key words: fruit tree, proteome, two-dimensional electrophoresis system
