23 de feb. de 2007 · Abstract. 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).
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. Field experiments conducted over two ye …
11 de dic. de 2021 · 1 INTRODUCTION. Sweet potato (Ipomoea batatas, family Convolvulaceae) is the third most important root and tuber crop globally (FAO, 2021).It is a highly fibrous and nutritious food crop with ornamental and medicinal value. It is recommended to consume orange and purple-fleshed sweet potatoes to prevent obesity, diabetes, cancer, and blindness (Loebenstein & Thottappilly, 2009).
6 de jul. de 2023 · Sweet potato virus disease (SPVD) is a global constraint to sweetpotato (Ipomoea batatas) production, especially under intensive cultivation in the humid tropics such as East Africa. The objectives of this study were to develop a precision SPVD phenotyping protocol, to find new SPVD-resistant genotypes, and to standardize the first stages of screening for SPVD resistance. The first part of the ...
This chapter describes the virus genome organisation, disease symptoms, diagnostic methods (biological indexing, serological tests, electron microscopy and molecular techniques), and management strategies of SPVD.
8 de jul. de 2014 · This review examines viral degeneration in sweetpotato in different regions of the World, particularly that caused by Sweet potato chlorotic stunt virus (SPCSV) and Sweet potato feathery mottle virus (SPFMV), comparing impacts on yield in single and complex infections of all the major viruses affecting the crop.
4 de abr. de 2021 · In this study, we performed deep sequencing of both messenger RNA (mRNA) and small RNA (sRNA) populations in an SPVD-susceptible cultivar ‘Beauregard’ upon viral infection, to identify biological pathways that contribute to both general and specific host responses to these important viral pathogens.
