Occurence and Yield Effects of Wheat Infected with Triticum Mosaic Virus Authors: D.L. Seifers, J.T. Martin, J.P. Fellers Submitted to: Plant Disease Triticum mosaic virus (TriMV) was discovered recently and little is known about the virus’ biology and potential to cause yield reductions. TriMV has been found all across the Great Plains and this study examined whether TriMV infection would re-o...

Like many other plant RNA viruses, Wheat streak mosaic virus (WSMV) sequence diversity within and among infected plants is low given the large number of virions produced. This may be explained by considering aspects of plant virus life history. Intracellular replication of RNA viruses is predominately linear, not exponential, which means that the rate at which mutations accumulate also is linea...

Oliveira-Hofman, C., Wegulo, S. N., Tatineni, S., and Hein, G. L. 2015. Impact ofWheat streak mosaic virus and Triticum mosaic virus coinfection of wheat on transmission rates by wheat curl mites. Plant Dis. 99:1170-1174. Wheat streak mosaic virus (WSMV) and Triticum mosaic virus (TriMV) are transmitted by the wheat curl mite (WCM, Aceria tosichella), and coinfections of wheat by these viruses ...

Wheat streak mosaic virus (WSMV) is a mite-vectored with substantial economic impact on wheat production. One of the effective sources resistance to WSMV, Wsm1, carried translocation from Thinopyrum intermedium. The original whole arm form this (T4DL·4JsS) was highly against WSMV but yield penalty in absence virus. Shorter recombinants Th. intermedium are now available. This study characterized...

The development of wheat (Triticum aestivum L.) cultivars that are resistant to Wheat streak mosaic virus (WSMV), yet competitive in yield under nondiseased conditions, is an objective for breeding programs in the Great Plains. This field study was conducted to compare classical and transgenic sources of resistance to WSMV. Three sets of germplasm were evaluated. These included adapted cultivar...

A series of in-frame and nested deletion mutations which progressively removed 5'-proximal sequences of the Wheat streak mosaic virus (WSMV) HC-Pro coding region (1152 nucleotides) was constructed and evaluated for pathogenicity to wheat. WSMV HC-Pro mutants with 5'-proximal deletions of 12 to 720 nucleotides systemically infected wheat. Boundary sequences flanking the deletions were stable and...

Cereals play a significant role in the Ukrainian economy and agriculture. Viral diseases can cause serious reduction yields. Aim. The aim of work was to identify determine spread grain viruses main cereal-growing regions Ukraine period 2020–2021 using different methods virus detection. Methods. Enzyme-linked immunosorbent assay used commercial test systems by for wheat streak mosaic (WSMV), bar...

Triticum mosaic virus (TriMV) (genus Poacevirus, family Potyviridae) is a recently described eriophyid mite-transmitted wheat virus. In vitro RNA transcripts generated from full-length cDNA clones of TriMV proved infectious on wheat. Wheat seedlings inoculated with in vitro transcripts elicited mosaic and mottling symptoms similar to the wild-type virus, and the progeny virus was efficiently tr...

Triticum mosaic virus (TriMV) and High plains (HPV), identified recently, have been considered among the major viruses that affect wheat. Carried by same vector, wheat curl mite, both of these cause yellowing stunting plants which are very similar to many other attacking This makes it difficult detect in different lines, posing a problem yield. paper highlights addition two multiplex RT-PCR bas...

Understanding the genetics underlying host range differences among plant virus strains can provide valuable insights into viral gene functions and virus-host interactions. In this study, we examined viral determinants and mechanisms of differential infection of Zea mays inbred line SDp2 by Wheat streak mosaic virus (WSMV) isolates. WSMV isolates Sidney 81 (WSMV-S81) and Type (WSMV-T) share 98.7...
