A barley cysteine-protease inhibitor reduces teh performance of two aphid species in artificial diets and transgenic arabidopsis plants [PDF]

open access: yes, 2011
Cystatins from plants have been implicated in plant defense towards insects, based on their role as inhibitors of heterologous cysteine-proteinases. We have previously characterized thirteen genes encoding cystatins (HvCPI-1 to HvCPI-13) from barley ...
