Double inoculation of soybean with Bean pod mottle virus (BPMV), a member of the Genus Comovirus, Family Comoviridae, isolates V-S98-1 and V-S98-15, together with Soybean mosaic virus (SMV) a member of the Genus Potyvirus, Family Potyviridae) isolates 2K-38, S98-51 and S98-52, was compared to single inoculation with each of the isolates, on Hutcheson, Hutcheson Roundup Ready® (RR BC3) and Hutch...

The recessive gene rymv-1, responsible for the high resistance of Oryza sativa 'Gigante' to Rice yellow mottle virus (genus Sobemovirus), was overcome by the variant CI4*, which emerged after serial inoculations of the non-resistance-breaking (nRB) isolate CI4. By comparison of the full-length sequences of CI4 and CI4*, a non-synonymous mutation was identified at position 1729, localized in the...

Turnip mosaic virus (TuMV, genus Potyvirus, family Potyviridae) infects mainly cruciferous plants. Isolates Tu-3 and Tu-2R1 of TuMV exhibit different infection phenotypes in cabbage (Brassica oleracea L.) and Japanese radish (Raphanus sativus L.). Infectious full-length cDNA clones, pTuC and pTuR1, were constructed from isolates Tu-3 and Tu-2R1, respectively. Progeny virus derived from infectio...

Byamukama, E., Tatineni, S., Hein, G. L., Graybosch, R. A., Baenziger, P. S., French, R., and Wegulo, S. N. 2012. Effects of single and double infections of winter wheat by Triticum mosaic virus and Wheat streak mosaic virus on yield determinants. Plant Dis. 96:859-864. Triticum mosaic virus (TriMV) is a recently discovered virus infecting wheat (Triticum aestivum) in the Great Plains region of...

Triticum mosaic virus (TriMV) is the type species of the newly established Poacevirus genus in the family Potyviridae. In this study, we demonstrate that in contrast to the helper component-proteinase (HC-Pro) of Potyvirus species, the P1 proteins of TriMV and Sugarcane streak mosaic poacevirus function in suppression of RNA silencing (SRS). TriMV P1 effectively suppressed silencing induced by ...

The RNAs of many plant viruses lack a 5' cap and must be translated by a cap-independent mechanism. Here, we discuss the remarkably diverse cap-independent translation elements that have been identified in members of the Potyviridae, Luteoviridae, and Tombusviridae families, and genus Tobamovirus. Many other plant viruses have uncapped RNAs but their translation control elements are uncharacter...

Introduction Species of the genus Beta are recognized as sources of various viruses. A con­ siderable number o f viruses have been isolated from the species Beta vulgaris var. saccharifera (sugar beet) (Sutic et al. 1999). One of the viruses occurring in this plant all over the world is beet mosaic potyvirus (BtMV). This virus belongs to Potyviridae, a taxonomic family of easily aphid-transmitt...
