Induction of resistance to potato virus Y strain NTN in potato plants through RNAi
Potato viruses cause enormous economic loss in agriculture production. Potatoes can be infected by a number of different viruses that affect negatively the harvest and the tuber quality. Direct and effective drugs against plant virus diseases are still not available and control is only applied as agricultural measures and pesticides against virus vectors. Potato virus Y (PVY) is transmitted by ...
متن کاملHeterologous Expression of Potato Virus Y Coat Protein, Isolate Pot187
Background: The advent of recombinant DNA technology has facilitated heterologous expression of proteins from various sources in different host systems including Escherichia coli. If a plant virus coat protein is expressed in the bacterium it can be used as the antigen for antibody preparation. Such a recombinant antigen preparation can be particularly useful where equipment such as ultracentri...
متن کاملA Model to Explain Temperature Dependent Systemic Infection of Potato Plants by Potato virus Y
The effect of temperature on the rate of systemic infection of potatoes (Solanum tuberosum L. cv. Chu-Baek) by Potato virus Y (PVY) was studied in growth chambers. Systemic infection of PVY was observed only within the temperature range of 16°C to 32°C. Within this temperature range, the time required for a plant to become infected systemically decreased from 14 days at 20°C to 5.7 days at 28°C...
متن کاملIMPACT OF POTATO VIRUS Y ON LONG-TERM STORAGE OF POTATO. Principal Investigator(s)
In recent years, Potato Virus Y has reemerged as a serious disease problem in many potato production areas in the northern United States and eastern Canada. Three recently introduced cultivars, ‘Russet Norkotah’, ‘Shepody’, and ‘Silverton’ are widely grown and express mild or no symptoms when infected with PVY. The lack of symptoms often associated with these cultivars and novel, recombinant st...
متن کاملPotato virus Y infection hinders potato defence response and renders plants more vulnerable to Colorado potato beetle attack
In the field, plants are challenged by more than one biotic stressor at the same time. In this study, the molecular interactions between potato (Solanum tuberosum L.), Colorado potato beetle (Leptinotarsa decemlineata Say; CPB) and Potato virus Y(NTN) (PVY(NTN) ) were investigated through analyses of gene expression in the potato leaves and the gut of the CPB larvae, and of the release of potat...
