Abstract
An isolated gene fragment that encodes for acetate kinase, which confers disease resistance in plants is disclosed. The gene can be cloned into an expression vector to produce a recombinant DNA expression system suitable for insertion into cells to form a transgenic plant transformed with the gene fragment. A method for conferring disease resistance in plants that consists of growing plant host cells transformed with the expression system and expressing the gene conferring disease resistance to impart such resistance to host cells is also disclosed.
Claims7
A method of conferring to a plant resistance to a fungal or bacterial pathogen, said method comprising regenerating a plant from plant cells expressing a chimeric nucleic acid molecule comprising in the 5′ to 3′ direction:
- (i) a promoter functional in a plant nucleus operably linked to (ii) a nucleic acid molecule or fragment thereof encoding a bacterial polypeptide having acetate kinase activity operably linked to (iii) a non-translated region of a nucleic acid molecule said region encoding an mRNA polyadenylation site, wherein expression of said chimeiic nucleic acid molecule in said plant confers resistance to a fungal or bacterial pathogen.
