Abstract
DNA sequences encoding plant viral proteins which contain modifications of the amino acid sequence -Gly1-Xaa1-Xaa2-Xaa3-Xaa4-Gly2-Lys- are disclosed. These modified proteins confer viral resistance when expressed in transformed plants. A method for providing resistance to infection by a geminivirus in a susceptible plant are disclosed. Plants expressing the modified genes which are resistant to viral infection are also disclosed.
