Comparative proteomic analysis of BTH and BABA-induced resistance in pea (Pisum sativum) toward infection with pea rust (Uromyces pisi)

► The 2DE analysis of pea leaves revealed 126 proteins changed in this study. ► A total of 50 spots were identified using a combination of PMF and MSMS fragmentations. ► Plants reduce their metabolism and enhance the production of defense-related proteins. ► BTH acting as a more potent inducer of defense-related proteins than BABA. ► Enzymes from isoflavonoid pathways were significantly increased with BABA inducer.
