Structure and Temporal Dynamics of Populations within Wheat Streak Mosaic Virus Isolates

Structure and temporal dynamics of populations within wheat streak mosaic virus isolates.

Variation within the Type and Sidney 81 strains of wheat streak mosaic virus was assessed by single-strand conformation polymorphism (SSCP) analysis and confirmed by nucleotide sequencing. Limiting-dilution subisolates (LDSIs) of each strain were evaluated for polymorphism in the P1, P3, NIa, and CP cistrons. Different SSCP patterns among LDSIs of a strain were associated with single-nucleotide...

Identification of wheat streak mosaic virus in iran

Evolution of Wheat streak mosaic virus: dynamics of population growth within plants may explain limited variation.

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...

Development of a multiplexed PCR detection method for Barley and Cereal yellow dwarf viruses, Wheat spindle streak virus, Wheat streak mosaic virus and Soil-borne wheat mosaic virus.

Barley and Cereal yellow dwarf viruses (B/CYDVs), Wheat spindle streak mosaic (WSSMV), Soil-borne wheat mosaic virus (SBWMV) and Wheat streak mosaic virus (WSMV) constitute the most economically important group of wheat viruses. In this paper, a multiplex reverse transcription polymerase chain reaction (M-RT-PCR) method was developed for the simultaneous detection and discrimination of eight vi...
