Phenotype

develops lesions resembling those produced during a pathogen-induced rapid cell death response (the hypersensitive response, HR); unable to control the rate and extent of cell death after exposure to a variety of stimuli that induce senescence responses; substantial ion leakage as an indicator of the loss of integrity of cell menbranes and cell death; rapid and spreading necrotic responses to both virulent and avirulent Pseudomonas syringae pv. maculicola or pv. tomato pathogens and to ethylene; develops necrotic lesions with aging; sensitive to mechanical stress in a developmentally controlled manner; susceptible to opportunistic pathogens and exhibits decreased growth inhibition of a heterologous pathogen of bean.
