cProtein database accession number (UniProt)
dPlant species from which the protein was annotated
eMASCOT score
fTheoretical molecular mass and isoelectric point computed from ExPASy Mr/pI calculation tool
gNumber of matched peptides of MSMS data with the corresponding protein in MSDB, SwissProt and NCBInr databases
hPercentage of peptide sequences coverage for the identified protein by MS/MS
iThe results of SignalP (SiP) and SecretomP (SeP) analysis. Y presence of signal peptide evaluated from SignalP. The numbers are Secretom NN score calculated from SecretomP, in case no signal peptides were identified, and the NN score >0.5 was considered as secretory protein as suggested by the author
