Appeal No. 95-1569
Application 07/865,169
Claims 1, 8, 9, 16, and 17 are the independent claims pending in this application
and read as follows:
1. A potato plant comprising a heterologous gene capable of causing the
expression of a pokeweed antiviral protein in said plant at a level sufficient to render said
plant resistant to infection by a virus selected from the group consisting of potato virus X
and potato virus Y.
8. A potato plant comprising a heterologous gene capable of causing the
expression of a pokeweed antiviral protein and the translocation of said protein to the cell
walls or vacuoles of said plant, said protein expressed at a level sufficient to render said
plant resistant to infection by a virus selected from the group consisting of potato virus X
and potato virus Y.
9. A potato tuber comprising a heterologous gene capable of causing the
expression of a pokeweed antiviral protein in said tuber at a level sufficient to render said
tuber resistant to infection by a virus selected from the group consisting of potato virus X
and potato virus Y.
16. DNA sequence encoding SEQ ID NO:2.
17. A method for providing viral resistance to infection by a virus selected from the
group consisting of potato virus X and potato virus Y in a potato plant or tuber comprising
causing the expression of a pokeweed antiviral protein in said plant or tuber.
