Novel bacterial strains are described which produce and secrete chitinase as a result of the introduction of foreign DNA linked to a sequence encoding chitinase, an enzyme that degrades chitin. The bacterial strains can be used to provide protection for plants against chitinase sensitive plant pathogens. Methods of preparing the chitinase producing bacterial cells are also described. Methods of protecting plants from chitinase sensitive pathogens are also described.

Chitinase-producing bacteria

Novel plants are described which produce and secrete chitinase as the result of the introduction of foreign DNA linked to a sequence encoding chitinase, an enzyme capable of degrading chitin present in fungi and nematodes. Novel plants that are resistant to cold damage are also described which are created by introduction of DNA encoding for the production of chitinase. The plants of the invention may also have enhanced levels of reducing sugars or sweetness, or produce fruit having enhanced levels of reducing sugars or sweetness, or may be selected for enhanced post-harvest storage life.

Chitinase-producing plants

Novel bacteria strains and plants are described which produce and secrete chitinase and other proteins as the result of the introduction of foreign DNA linked to a sequence encoding chitinase, an enzyme capable of degrading chitin present in fungi and nematodes. The bacterial strains have utility in producing chitinase for the purpose of inhibiting plant pathogens. Novel pathogen resistant plants are also described which are created by introduction of DNA encoding for the production of chitinase.

Novel bacteria strains are decribed which are created by the introduction of DNA encoding for the production of chitinase, an enzyme capable of degrading chitin present in fungi and nematodes. The strains have utility in producing chitinase for the purpose of inhibiting plant pathogens. Novel pathogen-resistant plants are also described which are created by introduction of DNA encoding for the production of chitinase.
