Nucleotide sequence of a new bipartite geminivirus isolated from the common weed Sida rhombifolia in Costa Rica

J Gen Virol. 1997 Jul:78 ( Pt 7):1785-90. doi: 10.1099/0022-1317-78-7-1785.

Abstract

The nucleotide sequence of infectious clones of a geminivirus from Costa Rica that infects Sida rhombifolia was determined. Sida golden mosaic virus (SiGMV-Co) has a bipartite genome (DNAs A and B). Computer analysis showed that the bipartite genome of SiGMV-Co resembles that of other whitefly-transmitted geminiviruses. The DNA A (2605 nt) and DNA B (2587 nt) components have little sequence homology other than within the common region (CR). Analysis of DNAs A and B showed that SiGMV-Co is closely related to bean dwarf mosaic virus (BDMV). SiGMV-Co was introduced via agroinoculation into seven plant species, including tomato and bean.
