Raw mass spectra data files were submitted to ProteinPilot software
(v.4.5, AB SCIEX) employing the Paragon Algorithm for peptide
and protein identification. Separate searches were conducted
against the Universal Protein Knowledge Base (UniProtKB, release
2014_09) for Glycine max and Fabaceae, each combined with a
database of common contaminants. The search parameters were
defined as iodoacetamide modified for cysteine alkylation and
trypsin as the digestion enzyme. The criteria for positive protein
identification were proteins with a ProteinPilotTM unused scoreP2,
P95% confidence and with a minimum of three unique peptides
