## Abstract

A method for producing genetically transgenic plants exhibiting resistance to a geminivirus such as tomato yellow leaf curl virus. In another aspect, the invention embraces chimeric plant genes, cassettes containing the chimeric plant genes, heterologous DNA segments containing the cassettes, and genetically transgenic cells and differentiated plants which exhibit resistance to geminiviruses. In yet another aspect, the invention embraces bacterial cells and plant transformation vectors comprising a heterologous DNA segment encoding for resistance to geminiviruses.
