The present invention relates to the isolation and identification of nucleic acid sequences encoding the coat protein of papaya ringspot virus in the Kapoho (KA), Keaau (KE), Thailand (TH), Brazil (BR), Jamaica (JA), Mexico (ME), Venezuela (VE), and Oahu (OA) strains, and the uses thereof to impart viral resistance to papaya plants. The present invention also relates to nucleic acid constructs containing individual or multiple papaya ringspot virus coat protein-encoding nucleic acid sequences, and host cells and transgenic plants and seeds containing such constructs. The present invention is also directed to a method of using such constructs to impart to plants resistance to papaya ringspot virus.

The present invention is directed to a DNA construct which includes a modified DNA molecule with a nucleotide sequence which is at least 80%, but less than 100%, homologous to two or more desired trait DNA molecules and which imparts the desired trait to plants transformed with the DNA construct. Each of the desired trait DNA molecules relative to the modified nucleic acid molecule have nucleotide sequence similarity values which differ by no more than 3 percentage points. The DNA construct may further include either a silencer or a plurality of modified DNA molecules. The present invention also relates to host cells, plant cells, transgenic plants, and transgenic plant seeds containing such DNA constructs. The present invention is also directed to a method of preparing a modified nucleic acid molecule suitable to impart multiple traits to a plant, a method of determining whether multiple desired traits can be imparted to plants by a single modified DNA molecule, and a method for imparting traits to plants by transforming the plants with the DNA construct.
