Poster: Improving Sweetpotato Virus Diagnostics

Virus infection, by a number of different types of viruses, is one of the most important constraints to sweetpotato production globally, especially in Sub-Saharan Africa (SSA). Sweet potato chlorotic stunt virus (SPCSV) and Sweet potato feathery mottle virus (SPFMV) are considered to be the most widespread and are particularly devastating when …

SEQUENCE ANALYSIS OF COAT PROTEIN GENE AND 3` NONCODING REGION OF SWEET POTATO FEATHERY MOTTLE VIRUS (SPFMV) ISOLATED FROM EGYPT

SWEET POTATO FEATHERY MOTTLE VIRUS

SWEET POTATO FEATHERY MOTTLE VIRUS (SPFMV) belongs to potyviruses, the largest group of plant positive sense single stranded RNA viruses. It has long been recognized to infect sweet potatoes worldwide. The virus is transmitted mechanically and by several genera of aphids including the cotton aphid (Aphis gossypii) and the green peach …

Complex Virus Diseases of Sweetpotato

Both components of the virus complex that cause the sweetpotato virus disease (SPVD) in Nigeria can individually be transmitted by their respective vectors from diseased sweetpotato to healthy sweetpotato and to test plant, Ipomoea setosa. But in Isolation, neither the aphid nor the whitefly-transmitted component, both latent in sweetpotato, can …

Comparison of methods to detect sweet potato feathery mottle virus (SPFMV) in sweet potatoes

Sensitive analytic techniques including double antibody sandwich enzyme linked immunosorbent assay (DAS-ELISA), direct ELISA, dot-ELISA and reverse transcription polymerase chain reaction (RT-PCR) are compared and evaluated for their capability to reliably distinguish between healthy and sweet potato feathery mottle virus (SPFMV) infected sweet potato plants. The DAS-ELISA is not adequate …

Expression of sweetpotato feathery mottle virus coat protein and production of specific anti-serum for diagnostic aspects

Sweetpotato (Ipomoea batatas L.) has a diverse range of positive characteristics including high yield per unit area, nutritional value, and resistance to several production stresses. However, diagnostics aspects for detection of sweetpotato feathery mottle virus (SPFMV) are not well understood. This paper documents such aspect via expression of SPFMV coat …
