From: Stress inducible proteinase inhibitor diversity in Capsicum annuum
MALDI-TOF-MS characterization of partially purified PIs from leaf extracts (systemic tissue in case of inductions). Mass spectral analysis revealed peaks of varying masses in the range of 5.5 to 6.3 kDa across treatments. These represent an1-IRD peptide, which was further confirmed by MS/MS analysis. The increased diversity of processed IRDs is prominent in C. annuum leaf tissues wounded and treated with water (W+W) or oral secretions (W + OS) as compared to aphid infested.
