Betasatellite

Betasatellite is a genus of family Tolecusatellitidae containing 119 species.^[1] They are small, circular, single-stranded DNA molecules that rely on helper viruses like Begomovirus for replication, movement, and encapsidation. These satellites encode a multifunctional protein known as βC1, which is approximately 13.5 kDa in size and plays a crucial role in the suppression of host plant defense responses, contributing to the severity of diseases caused by the associated viruses. ^[2][3]

Name

The name Betasatellite is a combination of Beta, because they used to be referred to as DNA-β to distinguish them from DNA-B of Begomovirus, and satellite, the fact that it is a satellite.^[4]

Taxonomy

The species are ssDNA unless specified ssDNA(+). There are 61 ssDNA(+) and 58 ssDNA viruses
