Inquiries into Wheat Streak Mosaic Virus and Other WSM Associated Viruses


Wheat Streak Mosaic WSM) is a complex disease found to cause severe impact on wheat yield. Wheat streak mosaic virus (WSMV Triticum Mosaic Virus (TMV) and Wheat Mosaic Virus (WMOV) are all transmitted by Aceria tosichella, the wheat cun mite, and have been reported as the viruses associated with WSM. There is a research project on the genetic composition of the associated viruses as well as determining any novel viruses that may be involved in the disease. The process has begun with the virus assessment of neid samples by RT-PCR and sanger Sequencing in a different study, the potential of a common Insect in wheat fields. Rhopalosiphum padi, the Bird cherry oat aphid, to be a vector for WSMV was Investigated. R. Daar was found to be not a vector of WSMV through RT-PCR. The other proiect screened some wid-relative wheat plants for WSMV resistance Various lines of Aeglos tauschii, a landrace wheat, were tested for viral resistance by assessing the viral copy number by RT-PCR. The Initial result has demonstrated that one of the four selected lines may have promising tolerance The preliminary tests performed for each Inquiry provides Insight to Improving the respective experiment design for further understanding of how concerned parties such as farmers may better combat the disease.
