The subject invention pertains to materials and methods that provide plants with resistance to plant pathogens and pests. Antibodies and aptamers that immunoreact or bind and inhibit the action of protein expression products from avirulence and/or phatogenicity genes, including, but not limited to, the Xanthomonas avr/pth family of such genes, are described. The antibodies of the subject invention function by blocking the action of the primary protein products of avr/pth genes by intercepting and denaturing them prior to their translocation to the plant nucleus. The method of the subject invention concerns transforming a plant with polynucleotide molecules that encode the antibodies. Expression of the antibodies in the plant confers resistance from pathogens and pests. The subject invention also pertains to polynucleotide molecules encoding the subject antibodies, as well as plants and plant tissue transformed with the polynucleotide molecules encoding the subject antibodies.
