Divergent functions of three Kunitz trypsin inhibitor (KTI) proteins in herbivore defense in poplar
KTI_400 and KTI_600 are potent, natural in-planta anti-herbivorous agents. Their expression is associated with larval growth reductions. Modulation of KTI_53200 levels had no direct effects on the fitness of leaf-feeding H. armigera or on plant growth. This study sheds light on the potential application of KTI in plant defenses and biocontrol against H. armigera in trees and presents new options to investigate growth-defense theories.
