Abstract
The nucleic acid and amino acid sequences for proteinaceous elicitors of the plant defense reaction known as the hypersensitive response are described along with methods for preparation and processes for inactivation.
Claims11
An isolated protein which elicits a hypersensitive response in different plant species when said protein is introduced into leaf tissue of a plant under normal plant growth condition, wherein said protein is encoded by a nucleic acid sequence which hybridizes to the nucleic acid of SEQ. ID. No. 4 under stringent conditions of 0.4 x SSC, 0.2% SDS washing at 65.degree. C. or wherein said protein is protease sensitive and heat stable at 100.degree. C. for at least one minute.
An isolated protein which elicits a hypersensitive response in different plant species when said protein is introduced into leaf tissue of a plant under normal plant growth conditions, wherein the hypersensitive response eliciting protein is from an Erwinia pathogen.
