Polerovirus Genomic Variation And Mechanisms Of Silencing Suppression By P0 Protein, Natalie Holste
Polerovirus Genomic Variation And Mechanisms Of Silencing Suppression By P0 Protein, Natalie Holste
School of Biological Sciences: Dissertations, Theses, and Student Research
The family Luteoviridae consists of three genera: Luteovirus, Enamovirus, and Polerovirus. The genus Polerovirus contains 32 virus species. All are transmitted by aphids and can infect a wide variety of crops from cereals and wheat to cucurbits and peppers. However, little is known about how this wide range of hosts and vectors developed. In poleroviruses, aphid transmission and virion formation is mediated by the coat protein read-through domain (CPRT) while silencing suppression and phloem limitation is mediated by Protein 0 (P0)—a protein unique to poleroviruses. P0 gives poleroviruses a great advantage amongst plant viruses and diversifies polerovirus species, but the …
Prevalence, Genetic Relationships, And Quantity Of Grapevine Vein Clearing Virus In Aphis Illinoisenesis, Adam Louis Uhls
Prevalence, Genetic Relationships, And Quantity Of Grapevine Vein Clearing Virus In Aphis Illinoisenesis, Adam Louis Uhls
MSU Graduate Theses
Grapevine vein clearing virus (GVCV) is an emerging pathogen causing severe damage to cultivated grapevines in the Midwest area of the United States. The prevalence of GVCV has been reported in native Vitis spp. and Ampelopsis cordata, a close relative of vitis in the Vitaceae family, which act as a reservoir for the virus. GVCV can be transmitted from wild A. cordata to Vitis spp. by Aphis illinoisensis (grape aphids) under greenhouse conditions, but the prevalence and transmission in native populations remains unknown. Knowing the prevalence and diversity of GVCV variants in natural grape aphid populations would help monitor …

Maize lethal necrosis is an intense viral disease spreading across sub-Saharan Africa. Maize is the staple crop grown in sub-Saharan Africa, but most crops infected with maize lethal necrosis will not survive to harvest. This causes immense economic hardship and starvation within the population. Maize lethal necrosis consists of a combination of two viruses, Maize chlorotic mottle virus (MCMV) and a virus from the genus potyvirus. In a recent study, a Maize yellow dwarf virus-RMV (MYDV-RMV)-like polerovirus, was repeatedly detected in plants with maize lethal necrosis. Poleroviruses have a silencing suppressor, P0 protein, and the mechanism of suppression is poorly …
