Additional file 4. Proteins with changed expression levels in O. europaea fruits after damage by Bactrocera oleae. 
The spot number, protein name, gene/EST number according to the NCBI database, protein entry in the NCBI database with the highest BLAST score, experimental pI/Mr values, peptide number/sequence coverage (%), Mascot score, identification method, organism, fold change for infested vs. control plants and GO classification are listed. All of the spots were identified by tandem MS.
