ABSTRACT:
An isolated nucleic acid molecule is provided which encodes a tobacco myb homologue involved in the regulation of disease resistance in plants. The encoded protein comprises a basic N-terminal region with two imperfect tryptophan repeats of 53 and 51 amino acids, a potential ATP/GTP binding site or P-loop, a redox sensitive cysteine and a nuclear localization sequence. The acidic C terminus of Myb1 forms amphipathic .alpha. helices which are characteristic of transcriptional activation domains. The invention also provides novel Myb1 protein and antibodies thereto. Additionally, the invention provides novel transgenic plants with enhanced disease resistance to certain pathogens.
