Sweetpotato Virus Diseases (SPVD): Research Progress

doi:10.11924/j.issn.1000-6850.casb18060093

Abstract

Abstract: Sweetpotato virus disease (SPVD), which is caused by the dual infection and synergistic interaction of Sweetpotato feathery mottle virus (SPFMV) and Sweetpotato chlorotic stunt virus (SPCSV), is a devastating viral disease of sweetpotato. Since reported in China in 2012, it has been expended rapidly, and in 2015 it caused huge economic losses to sweetpotato production in Zhanjiang of Guangdong. In order to strengthen the prevention and control of sweetpotato virus disease and reduce losses, the distribution and harm of SPVD are summarized, and the gene structure and function, transmission and detecting means of SPFMV and SPCSV are reviewed respectively. It is suggested that in serious disease areas, detection of virus strains should be a key point, and molecular mechanism study about synergism between SPFMV and SPCSV should be further explored, thus to achieve the timely detection, early prevention and non-toxic cultivation of sweetpotato.
