title: Structure and replication of geminivirus genomes.
abstract: The geminiviruses are a group of plant viruses containing single-stranded (ss) DNA in particles comprising two quasi-icosahedral units. Some are transmitted by whiteflies, others by leafhoppers. Comparisons were made of the genome organization and expression of cassava latent virus (CLV) and maize streak virus (MSV) and beet curly top virus (BCTV), each with distinct host range and insect vector species characteristics. From these studies, several indications as to the replication mechanism(s) are suggested.
