Sweet potato virus disease (SPVD) is caused by dual infection of plants with Sweet Potato Feathery Mottle Virus (SPFMV) and Sweet Potato Chlorotic Stunt Virus (SPCSV). Because SPFMV and SPCSV are transmitted by aphids and whiteflies, respectively, infection in nature occurs independently rather than simultaneously. To investigate the effect of consecutive infection on symptom development and individual virus titres, plants infected with a single virus were later inoculated with the second virus… Expand
Differential Gene Expression of Resistant and Susceptible Sweetpotato Plants after Infection with the Causal Agents of Sweet Potato Virus Disease
TLDR
Results show that induction of protein synthesis genes also occurs early in the infection process in resistant plants, while virus titers were below the level of detection, suggesting that virus accumulation is not required for induction. Expand
Sweetpotato Viruses: 15 Years of Progress on Understanding and Managing Complex Diseases.
TLDR
This article is intended to summarize what has been learned since earlier reviews, integrate knowledge gleaned from experiences in tropical and temperate production systems, and suggest courses of action to develop sustainable management programs for sweetpotato virus diseases. Expand
Sweetpotato Virus C and Its Contribution to the Potyvirus Complex in Sweetpotato (Ipomoea batatas)
TLDR
The present study presents a meta-analysis of the phytochemical properties of sweetpotato affected by SPVG, SPVC, SPHFV, SPFMV and SPV2, which reveals polypeptide-like structures in the phytonutrients responsible for storage root development and cultivar decline and the structure of the viruses responsible for this decline.

Interactions Among Sweet potato chlorotic stunt virus and Different Potyviruses and Potyvirus Strains Infecting Sweetpotato in the United States.
TLDR
Titers of all potyviruses and potyvirus strains evaluated were enhanced in the presence of SPCSV, suggesting that a conserved mechanism may underlie these interactions. Expand
Sweetpotato Virus Disease (SPVD): Distribution, Incidence, and Effect on Sweetpotato Yield in Peru.
TLDR
It is demonstrated that SPFMV and SPCSV interact synergistically and that the severity of SPVD symptoms also depends on the particular isolate of each virus. Expand
Synergistic interactions of a potyvirus and a phloem-limited crinivirus in sweet potato plants.
TLDR
It is hypothesized that SPCSV is able to enhance the multiplication of SPFMV in tissues other than where it occurs itself, perhaps by interfering with systemic phloem-dependent signaling required in a resistance mechanism directed against SP FMV. Expand
Effects of Common Viruses on Yield and Quality of Beauregard Sweetpotato in Louisiana.
During cycles of vegetative propagation, sweetpotato accumulates viruses that are thought to contribute to decline in yield and quality of cultivars, but the effects of specific viruses, many ofExpand
Real-Time PCR Assays for Detection and Quantification of Sweetpotato Viruses.
TLDR
Real-time PCR was a more efficient detection method for SPLCV than conventional PCR assay and virus titers of SPFMV, IVMV, and SPVG were found to be lower in singly infected sweetpotato plants compared with singlyinfected Brazilian morning-glory and I. Scarlet O'Hara plants. Expand
Analysis of gene content in sweet potato chlorotic stunt virus RNA1 reveals the presence of the p22 RNA silencing suppressor in only a few isolates: implications for viral evolution and synergism.
TLDR
The results indicate that any efforts to engineer pathogen-derived RNA silencing-based resistance to SPCSV and SPVD in sweetpotato should not rely on p22 as the transgene, and provides the first example of intraspecific variability in gene content of the family Closteroviridae. Expand
Effects of Viruses (SPVD) on Growth and Yield of Sweet Potato
TLDR
Loss of tuberous root yield due to SPVD was studied in sweet potato showing symptoms of the disease, and yield was reduced by 78% in plants showing SPVD symptoms but the reduced chlorophyll level of diseased leaves did not appear to affect yield. Expand
Yield stability and yield depression in sweet potato cultivars susceptible to the sweet potato virus disease.
Eight sweet potato cultivars were used in two studies—one to determine the yield depression caused by the sweet potato virus disease (SPVD) in cultivars differing in their response to SPVD, and theExpand
Viral Class 1 RNase III Involved in Suppression of RNA Silencing
TLDR
It is shown that RNase3 has dsRNA-specific endonuclease activity that enhances the RNA-silencing suppression activity of another protein (p22) encoded by SPCSV, and this work provides evidence that a class 1 RNase III is involved in suppression of RNA silencing. Expand
Gene silencing as an adaptive defence against viruses
Gene silencing was perceived initially as an unpredictable and inconvenient side effect of introducing transgenes into plants. It now seems that it is the consequence of accidentally triggering theExpand
