^aProtein identification numbers are same as the gene IDs of the F. virguliforme genome database (http://fvgbrowse.agron.iastate.edu) [56].

^bNumber of times the peptides were identified from five biological replicates of xylem saps collected from F. virguliforme-infected soybean plants. The total number of times a peptide(s) was identified is presented in parentheses.

^CExponentially modified protein abundance index. This equals to 10^PAI-1, which is proportional to the protein content in a protein mixture.
