Induction of Resistance to Potato Virus Y (PVY) Using Hairpin Construct of Coat Protein
Potato virus Y (PVY) is one of the most damaging viruses of potato plants which infecting most cultivars and causing significant yield and economical losses. The application of the concept of pathogen derived resistance opened new horizons for the development of virus-resistant plants. This research was carried out to study RNA silencing to engineered potato plants that are resistant to potato ...

متن کاملEarly selection of potato clones with resistance genes: the relationship between combined resistance and agronomical characteristics
Cultivating resistant varieties of potato is the most effective and environmentally safe method of protecting against pests and diseases that affect potato crops. Therefore, potato breeding is focused on developing more resistant varieties so that the use of plant health products can be reduced during the cultivation cycle. Resistance to late blight, viruses and nematodes is the most important ...
متن کاملIdentiWcation of molecular markers associated with sweet potato resistance to sweet potato virus disease in Kenya
Sweet potato virus disease (SPVD), a result of the co-infection of whiteXy transmitted Sweet potato chlorotic stunt virus (genus Crinivirus, family Closteroviridae) and the aphid transmitted Sweet potato feathery mottle virus (genus Potyvirus, family Potyviridae), is the most destructive disease of sweet potato in East Africa. A study was conducted to establish if genotypes identiWed as resista...
متن کاملSCAR marker for the selection of Ry-duplex potato clones immune to potato virus Y
Vegetative propagation of potato allows the dissemination of viruses that can cause drastic drops in tuber yield. Potato virus Y (PVY) is one of the most important viruses of potato due to the non-persistent mode of transmission through vector insects. Genetic resistance is the recommended control measure since the chemical control of vector insects is not effective. This study aimed to identif...
