The Genetic Engineering of Two Commercial Potato Cultivars for Resistance to Potato Virus X

Transgenic Nicotiana debneyii expressing viral coat protein are resistant to potato virus S infection

“…This form of coat proteinmediated protection has now been demonstrated for a number of different viruses including alfalfa mosaic virus (A1MV; Van Dun et al, 1987;Tumer et al, 1987;Loesch-Fries et al, 1987), cucumber mosaic virus (CMV; Cuozzo et al, 1988), tobacco rattle virus , tobacco streak virus and PVX (Hemenway et al, 1988;Hoekema et al, 1989). More recently, simultaneous resistance to two viruses, PVX and potato virus Y, has been reported in transgenic potato plants expressing the nucleocapsid proteins from each of these viruses (Lawson et al, 1990).…”

Molecular cloning and nucleotide sequencing of the coat protein gene of citrus tristeza virus

“…Transgenic plants expressing coat protein genes of virus pathogens show delayed disease development or are resistant to infection upon inoculation with the respective virus. This form of resistance has been shown for tobacco mosaic virus, alfalfa mosaic virus, tobacco rattle virus, cucumber mosaic virus, potato virus X and potyviruses (Powell Abel et al, 1986;Loesch-Fries et al, 1987;VanDun et al, 1987;VanDun & Bol, 1988;Tumer et al, 1987;Cuozzo et al, 1988 ;Hemenway et al, 1988;Hoekema et al, 1989;Stark & Beachy, 1989). The wide applicability of this method offers promise for coat protein-mediated protection of citrus plants.…”

Transgenic Plants and Insect Cells Expressing the Coat Protein of Arabis Mosaic Virus Produce Empty Virus-like Particles

“…Much plant transformation has been aimed at the production of virus-resistant plants, the most successful strategy for which has been transformation, such that plants express the coat protein gene (PoweU-Abel et al, 1986;Van Dun et al, 1987;Tumer et al, 1987;Loesch-Fries et al, 1987;Cuozzo et al, 1988;Van Dun & Bol, 1988;Hemenway et al, 1988;Hoekema et al, 1989;MacKenzie & Tremaine, 1990). Since the degree of protection is correlated with the amount of coat protein produced in the plants (Nejidat & Beachy, 1989), we sought to maximize the coat protein production using the 'omega-prime' translation enhancer sequence derived from tobacco mosaic virus (Gallie et al, 1987).…”
