POTYVIRUS COAT PROTEIN GENES AND PLANTS TRANSFORMED THEREWITH

摘要

The present invention relates to the coat protein genes of Papaya Ringspot Virus Strain papaya ringspot (PRV-p), Watermelon Mosaic Virus II (WMVII), and Zucchini Yellow Mosaic Virus (ZYMV); to expression vectors which contain a coat protein gene for PRV-p, WMVII or ZYMV, and, additionally, the necessary genetic regulatory sequences needed for expression of a gene transferred into a plant; to bacterial or plant cells which are transformed with an expression vector containing the PRV-p, WMVII or ZYMV coat protein genes; to transgenic plants which are produced from plant cells transformed with an expression vector containing the coat protein gene from PRV-p, WMVII or ZYMV; and to a process of producing transgenic plants which have increased resistance to viral infection.
