Utility of thermotherapy and meristem tip for freeing sweetpotato from viral infection

Sweetpotato, (Ipomoea batatas L.), is vegetatively propagated crop. Due to the following cycles of propagation, viruses are accumulated, which contributes to the decline of sweetpotato yield and quality. Stem cuttings of Abees cultivar were collected from several locations in Egypt and kept under controlled greenhouse conditions. Samples were tested for …

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 …

Synergistic Interaction of Sweet potato chlorotic stunt virus (Crinivirus) with Carla-, Cucumo-, Ipomo-, and Potyviruses Infecting Sweet Potato

Co-infection of Sweet potato chlorotic stunt virus (SPCSV, genus Crinivirus) with Sweet potato feathery mottle virus (SPFMV, genus Potyvirus) results in sweet potato virus disease (SPVD), a synergistic disease that is widely distributed in the sweet potato (Ipomoea batatas) growing regions of the world. Since both SPCSV and SPFMV are …

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 …
