Differential Transmission of Two Isolates of Wheat streak mosaic virus by FiveWheat Curl Mite Populations

Wosula, E. N., McMechan, A. J., Oliveira-Hofman, C., Wegulo, S. N., and Hein, G. L. 2016. Differential transmission of two isolates ofWheat streak mosaic virus by five wheat curl mite populations. Plant Dis. 100:154-158. Wheat streakmosaic virus (WSMV), typemember of the genusTritimovirus in the family Potyviridae, is an economically important virus causing annual average yield losses of approx...

Wheat streak mosaic virus coat protein is a host-specific long-distance transport determinant in oat.

Viral determinants involved in systemic infection of hosts by monocot-infecting plant viruses are poorly understood. Wheat streak mosaic virus (WSMV, genus Tritimovirus, family Potyviridae) exclusively infects monocotyledonous crops such as wheat, oat, barley, maize, triticale, and rye. Previously, we reported that WSMV CP amino acids 36-84 are expendable for systemic infection of wheat, maize,...

Impact of Wheat streak mosaic virus and Triticum mosaic virus Coinfection ofWheat on Transmission Rates by Wheat Curl Mites

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 ...

Development of Serological Procedures for Rapid and Reliable Detection of Wheat Streak Mosaic Virus in a Single Wheat Curl Mite

Brief Report Substitution of conserved cysteine residues in wheat streak mosaic virus HC-Pro abolishes virus transmission by the wheat curl mite

Substitutions in the amino-proximal region of wheat streak mosaic virus (WSMV) HC-Pro were evaluated for effects on transmission by the wheat curl mite (Aceria tosichella Keifer). Alanine substitution at cysteine residues 16, 46 and 49 abolished vector transmission. Although alanine substitution at Cys20 had no effect, substitution with arginine reduced vector transmission efficiency. Random su...
