Occurrence of Cowpea mild mottle virus in Common Bean and Associated Weeds in Northeastern Brazil

Abstract

Cowpea mild mottle virus (CPMMV - Carlavirus, Betaflexiviridae) is a positive single-stranded RNA virus transmitted by the whitefly Bemisia tabaci. Common bean is a staple food in Brazil, and virus-associated diseases can cause important crop losses. The first report of CPMMV in Brazil was in common bean (Phaseolus vulgaris L.) in the states of Sao Paulo and Parana, causing angular yellow mosaic. More recently, CPMMV has re-emerged and was frequently found infecting beans in Goias State and Distrito Federal, located in central Brazil. However, in the northeastern region, CPMMV infection in common bean plants has not been reported.
