  1. aMowse scores greater than the significance threshold indicate identity or extensive homology (p < 0.05). Three database have their respective significance thresholds, the EST_Har database is 31, the NCBInr database is 46, and the NCBI EST_others database is 57.bAdditional data for single peptide-based identifications are presented in Additional file 2: Figure S2.
