The invention provides methods, compositions and transformation systems for modifying the levels of transcription factors in plants such asplants, and introducing disease resistance genes into plants, to produce products with elevated levels of antioxidant compounds, including but not limited to flavonols and chlorogenic acid, as well as exhibiting enhanced disease resistance, and optionally altered appearance. Preferred plants are those in which introduced genes are fromspecies.

This invention provides novel gene sequences, compositions and methods for enhancing the resistance in crops, in particular but not limited to, potato, to late blight caused by the oomycete pathogen

Late blight resistance genes and methods

The tomato Cf-5 gene has been cloned and its sequence provided, along with the encoded amino acid sequence. DNA encoding the polypeptide, may be introduced into plant cells and expressed, conferring pathogen resistance on plants comprising such cells and descendants thereof.

Plant pathogen resistance genes and uses thereof

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.

This invention relates to the discovery that the prokaryotic enzyme, aminoglycoside 3'-adenyltransferase (AGAT), in particular as encoded by a bacterial aadA gene, is useful as a selectable marker for transformed plants. The enzyme conveys resistance to spectinomycin and streptomycin. Such markers are particularly advantageous because they are non-lethal, provide rapid visual identification of transformed cells and permit selection in media containing either spectinomycin or streptomycin. In addition, AGAT may be used as a selectable marker which differentiates by enabling survival on selective media.

Method of introducing spectinomycin resistance into plants

This invention relates to improved methods for transposon tagging as a route to plant gene isolation. The specific improvements comprise efficient means for preselecting plants which have undergone transposition. Through use of this preselection, it is possible to substantially reduce the number of plants which must be inspected to locate individuals having the transposon excised and inserted into a gene of interest. The result is a substantial savings in time, costs and efficiency associated with growing and screening large numbers of plants for tagging and isolation of a desired plant gene.

Transposon tagging of genes in transformed plants

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.
