Abstract

A bean golden mosaic geminiviral isolate from Goiania, Goias, Brazil (BGMV-BZ), was determined to be transmitted by whiteflies and induced golden mosaic symptoms and diagnostic geminiviral inclusion bodies and ultrastructural abnormalities in infected bean leaves. In contrast to BGMV isolates from Central America and the Caribbean, BGMV-BZ could not be sap-transmitted to beans. Cloned geminiviral DNA components were used as DNA probes for the rapid and specific detection of BGMV-BZ and three sap-transmissible bean-infecting geminiviral isolates-BGMV from Guatemala (GBMV-GA) and the Dominican Republic (BGMV-DR) and bean dwarf mosaic geminivirus from Colombia (BDMV-CO) (.)
