physiological function | Xanthomonas campestris pv vesicatoria effector AvrBsT induces a hypersensitive cell death in pepper. Arginine decarboxylase isoform ADC1 is an AvrBsT-interacting protein, which is early and strongly induced in incompatible interactions between pepper and Xanthomonas campestris. The ADC1-AvrBsT complex is localized to the cytoplasm. Transient coexpression of ADC1 with avrBsT in Nicotiana benthamiana leaves specifically enhance AvrBsT-triggered cell death, accompanied by an accumulation of polyamines, nitric oxide, and hydrogen peroxide bursts. ADC1 silencing in pepper leaves significantly compromises NO and H2O2 accumulation and cell death induction, leading to the enhanced avirulent Xcv growth during infection. The levels of salicylic acid, polyamines, and g-aminobutyric acid, and the expression of defense response genes during avirulent Xcv infection, are distinctly lower in ADC1-silenced plants than those in the empty vector control plants | Capsicum annuum |
