The invention provides phenylalanine ammonia-lyase (PAL) sequences, and constructs and methods related thereto. In one aspect,PAL sequences are isolated and characterized. The invention also provides novel sequences associated with PAL polynucleotide sequences and methods using recombinant techniques to express proteins from such sequences. In addition, methods are provided for using such sequences to transform host cells and alter wound induced gene activity or expression.

Novel bacteria strains are described 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.

Chitinase-producing bacteria

Bacteriophage-resistant plant growth promoting rhizobacteria are employed for enhancing the yield of root crops, such as potatoes, sugar beets, radishes and the like, grown in soils which are infected by bacteriophage which limit the root colonization by the corresponding wild-type rhizobacteria. The strain SH5 PR3 was deposited at the ATCC for patent purposes on Jan. 20, 1983, and granted Accession No. 39270.
