Molecular characterization of two bipartite geminiviruses causing squash leaf curl disease: role of viral replication and movement functions in determining host range.

Abstract excerpt

The genomes of two distinct, but highly homologous, bipartite geminiviruses have been identified in and cloned from extracts of squash leaf curl diseased field squash. These two squash leaf curl viruses (SqLCVs) have covalently closed, circular single-stranded DNA genomes with the same bipartite component organization characteristic of other whitefly-transmitted geminiviruses. Infectivity studies using virus...
