Findings on Viral RNA Detailed by Investigators at Institute for Virology (Transgenic rice expressing rice stripe virus NS3 protein, a suppressor of RNA silencing, shows resistance to rice blast disease)

By a News Reporter-Staff News Editor at Life Science Weekly -- Current study results on Viral RNA have been published. According to news reporting from Hangzhou, People's Republic of China, by NewsRx journalists, research stated, "The NS3 protein of rice stripe virus (RSV), encoded by the virion strand of RNA3, is a viral suppressor of RNA silencing (VSR). Rice expressing NS3 had a normal phenotype, was initially sensitive to RSV but recovered at the later stages of infection."

The news correspondents obtained a quote from the research from Institute for Virology, "RSV accumulated slightly more in transgenic than in wild-type plants at the early stage of infection, but accumulation was similar later. Transgenic rice expressing NS3 also showed enhanced resistance to the fungus Magnaporthe oryzae. Meanwhile, expressional levels of genes related to the salicylic acid (SA) and jasmonic acid (JA) pathways were not significantly altered, indicating that the defense to M. oryzae was independent of the SA and JA pathways."

According to the news reporters, the research concluded: "We propose that NS3 may have dual functions, facilitating viral infection as a VSR and inhibiting pathogenic development as an inducer of host defense."
