The complete nucleotide (nt) sequence of a Brazilian isolate of bean golden mosaic geminivirus (BGMV-BZ) was determined from the infectious cloned DNA components. The genome of BGMV-BZ was divided between two DNA components, DNA-A (2,617 nt) and DNA-B (2,580 nt), which had little sequence identity except for a 181-nt common region present in both molecules. The genomic organization of BGMV-BZ was similar to that of other bipartite whitefly-transmitted geminiviruses, with six open reading frames (ORFs) encoding putative proteins >10 kDa, four on DNA-A (one in the viral [+] and three in the viral complementary sense [-]) and two on DNA-B (one in the viral and one in the viral complementary sense) [...]
