Disclosed are peptides that have enhanced stability against plant proteases and are useful in the control of plant diseases. The peptides also have the ability to protect other peptides, polypeptides or proteins from degradation by proteases of plant, fungal, viral, bacterial, insect or other origin. DNA encoding the peptides of the present invention can be co-expressed with other DNA encoding exogenous peptides in transgenic plants as a method for protecting foreign peptides from degradation by proteases. Also disclosed are nucleic acid sequences, microorganisms, plants, and compositions useful for the treatment of plant diseases.

Peptides with enhanced stability to protease degradation

An isolated gene fragment that encodes for acetate kinase, which confers disease resistance in plants is disclosed. The gene can be cloned into an expression vector to produce a recombinant DNA expression system suitable for insertion into cells to form a transgenic plant transformed with the gene fragment. A method for conferring disease resistance in plants that consists of growing plant host cells transformed with the expression system and expressing the gene conferring disease resistance to impart such resistance to host cells is also disclosed.

Use of bacterial acetate kinase and their genes for protection of plants against different pathogens

The use of an avr gene hrmA to induce systematic acquired resistance in plant cells, plant seeds, plant tissues and plants is disclosed. Also disclosed is the use of low level expression of promoters in combination with the hrmA gene to provide broad-spectrum pathogen resistance in plant cells, plant seeds, plant tissues and plants.

Use of HrmA proteins and their genes for broad range protection of plants against bacterial, fungal and viral pathogens
