  1. Data are from 4 independent biological experiments for each treatmentaStudent’s t-test p values are given as a measure of confidence for the ratio of each spot measured
  2. bAverage ratios of spot abundance of salt-treated samples relative to the untreated control represent data from four independent experiments
  3. cProtein names, dGO cellular location and eGO biological function annotations are taken from the Uniprot database recommended name and annotation
  4. f p < 0.05; Peptide sequences, % sequence coverage, best Mascot ion, charge and delta ion score as well as spectra charge states can be seen for all identified proteins in Additional file 5
  5. gTheoretical molecular weight and isoelectric point for each protein spot identified
