LETTUCE INFECTIOUS YELLOWS VIRUS GENES

摘要

The present invention provides an isolated nucleic acid which contains a nucleotide sequence which encodes at least one of five LIYV proteins: the coat protein, the heat shock protein-70, RNA polymerase, the protein encoded by the gene positioned at ORF 3 of LIYV RNA1, and the protein encoded by the gene positioned at ORF 6 of LYIV RNA2 where at least a portion of the nucleotide sequence for at least one of these proteins, either in the sense or the antisense orientation, is operably linked to genetic regulatory sequences necessary for gene expression to form plant transformation vectors. These vectors are then used to prepare transgenic seeds and plants.
