Viral resistance can be effectively induced in transgenic plants through their silencing machinery. Thus, we designed nine short hairpin RNAs (shRNA) constructs to target nuclear inclusion protein b (NIb), helper component proteinase (HC-Pro), cylindrical inclusion protein (CI) and viral protein genome linked (VPg) genes of Potato virus Y (PVYN) and Tobacco(More)
Two types of hairpin RNA (hpRNA) constructions were designed using a chimeric gene formed from two genes, the coat protein (CP) gene or the silencing suppressor gene, from the Cucumber mosaic virus (CMV) and the Potato virus Y (PVYN), respectively; one type generated a single hairpin structure, whereas the other formed a two-hairpin structure. Four(More)
BACKGROUND Sugarcane mosaic virus (SCMV) is responsible for large-scale economic losses in the global production of sugarcane, maize, sorghum, and some other graminaceous species. To understand the evolutionary mechanism of SCMV populations, this virus was studied in Shanxi, China. A total of 86 maize leaf samples (41 samples in 2012 and 45 samples in 2013)(More)
Control of Cucumber mosaic virus (CMV) and Tobacco etch virus is difficult (TEV) mainly because of the lack of resistant tobacco varieties. In this study, the resistance to CMV and TEV of 22 tobacco cultivars, grown under both greenhouse and field conditions, was evaluated from 2007 to 2012. The genetic relationships among these cultivars were also assessed(More)
