10 de abr. de 2020 · Sweet potato virus disease (SPVD) is the most devastating viral disease in sweet potato (Ipomoea batatas (L.) Lam.), causing substantial yield losses worldwide. We conducted a systemic investigation on the spread, transmission, and pathogenesis of SPVD.
23 de feb. de 2007 · Sweetpotato virus disease (SPVD), the most important disease affecting sweetpotato ( Ipomoea batatas (L.) Lam), is caused by the synergistic interaction of the aphid-transmitted Sweetpotato feathery mottle virus (SPFMV) and whitefly-transmitted Sweetpotato chlorotic stunt virus (SPCSV).
8 de jul. de 2014 · SPCSV is the most damaging virus affecting individual sweetpotato plants, causing permanent symptoms even when infecting alone. It is particularly common in Africa and epidemiologically is the key virus there, synergizing SPFMV so it is easier to acquire by vectors (Gibson & Aritua, 2002 ).
30 de ago. de 2021 · The results highlight the high diversity of the sweet potato viromes in China. The full-length or nearly full-length genomic sequences of 111 isolates were obtained, belonging to 18 sweet potato virus species, and the molecular diversity of major sweet potato viruses was analyzed.
11 de ene. de 2012 · Viral metagenomics reveals sweet potato virus diversity in the Eastern and Western Cape provinces of South Africa
The main viruses worldwide are Sweet potato feathery mottle virus (SPFMV) and Sweet potato chlorotic stunt virus (SPCSV). Effects on yields by SPFMV or SPCSV alone are minor, or but in complex infection by the two or other viruses yield losses of 50%.
1 de jul. de 2023 · Sweet potato virus disease (SPVD) caused by synergistic interaction between sweet potato chlorotic stunt virus (SPCSV) and sweet potato feathery mottle virus (SPFMV) can cause between 56% and 98% yield losses.
