Fig. 4From: Chemical hybridizing agent SQ-1-induced male sterility in Triticum aestivum L.: a comparative analysis of the anther proteomeProtein interaction network analysis using STRING 10.0. DEPs were mapped to Brachypodium distachyon homologs by searching the STRING 10.0 database (http://string-db.org) with a confidence cutoff of 0.4. Colored lines between the proteins indicate the type of interaction evidence. Details of all the protein nodes are listed in Additional file 5: Table S2aBack to article page
