Abstract
Compositions and methods to aid in protecting the plant from invading pathogenic organisms are provided. The compositions of the invention comprise genes that influence the levels of nitric oxide in plant cells. Such genes include those encoding nitric oxide synthase (iNOS) as well as natural resistance-associated macrophage proteins (NRAMP) and NRAMP homologues. A pathogen inducible promoter or alternatively a constitutive, preferably a weak constitutive, promoter is used to control the desired level of disease control in the plant. Transformed plants, plant cells, tissues, and seed are also provided having enhanced disease resistance.
