Barley stripe mosaic virus and the frequency of triploids and aneuploids in barley.

Impact of Seed-transmitted Viruses on Quality of Cereal Seeds

Among seed-transmitted cereal viruses the most important is Barley stripe mosaic virus (BSMV), infecting barley. Investigations on the occurrence of BSMV in Poland have been carried out in the Institute of Plant Protection in Poznań since 2000. The studies aimed at the evaluation of the BSMV distribution in plant material, the rate of its seed transmission in different barley cultivars and the ...

A Non-capsid Protein Associated with Unencapsidated Virus RNA in Barley Infected with Barley Stripe Mosaic Virus

Movement of a barley stripe mosaic virus chimera with a tobacco mosaic virus movement protein.

The tobacco mosaic virus (TMV) 30K movement protein (MP) gene was inserted into a full-length cDNA clone of barley stripe mosaic virus (BSMV) RNA beta replacing the triple gene block (TGB). The resulting recombinant ND-MPT genome, consisting of infectious wt transcripts of BSMV RNAs alpha and gamma, together with the hybrid RNA beta transcript, was inoculated onto test plants to study the funct...

Functional analysis of drought-resistant genes in barley using VIGS

The following study analyzed the role of the gamma-aminobutyric acid transaminase (GABAT) gene in the response of barley plants to drought stress. Expression of GABAT in barley was suppressed using virus-induced gene silencing (VIGS). In VIGS, an RNA virus is used to replicate a small portion of the target RNA. In this study, barley stripe mosaic virus (BSMV), that carries a piece of the GABAT ...

Fine Mapping of the Bsr1 Barley Stripe Mosaic Virus Resistance Gene in the Model Grass Brachypodium distachyon

The ND18 strain of Barley stripe mosaic virus (BSMV) infects several lines of Brachypodium distachyon, a recently developed model system for genomics research in cereals. Among the inbred lines tested, Bd3-1 is highly resistant at 20 to 25 °C, whereas Bd21 is susceptible and infection results in an intense mosaic phenotype accompanied by high levels of replicating virus. We generated an F(6:7) ...
