Plants employ diverse responses mediated by phytohormones to defend themselves against pathogens and herbivores. Adapted pathogens and herbivores often manipulate these responses to their benefit. Previously, we demonstrated that Turnip mosaic virus (TuMV) infection suppresses callose deposition, an important plant...

Proteinase 3 (Pr3), and human neutrophil elastase (HNE) are two major neutrophilic serine proteases (NsPs) expressed in neutrophil azurophil granules. Emerging data suggest that excessive release of proteases mediates tissue damage, and therefore prolonged neutrophil accumulation has an important role...
