Abstract
1. Introduction
1.1. Structure and Function of Begomovirus Satellite Molecules
1.2. Betasatellites (Family Tolecusatellitidae)
1.3. Alphasatellites (Family Alphasatellitidae)
1.4. Deltasatellites (Family Tolecusatellitidae)
2. Role of DNA Satellites in Virus Disease Development
2.1. Interaction Between Betasatellites and Associated Helper Begomoviruses Is Synergistic
βC1 RNA-Silencing Suppression Function Contributes to Betasatellite Enhancement of Helper Virus Symptoms
2.2. Alphasatellites Tend to Attenuate Symptoms in Coinfections with Helper Viruses
Alphasatellite Attenuation of Begomovirus Disease Symptoms May Be Due to -Rep Interaction with the Helper Virus Rep
2.3. Deltasatellites Do Not Enhance Helper Virus DNA Levels or Symptom Severity
2.4. DNA Satellites’ Complementation of Begomoviruses from Different Regions May Lead to New Disease Epidemics
3. Recombination Between Helper Viruses and DNA Satellites Contributes to Virus and Satellite Evolution
4. Cassava Geminivirus-Associated SEGS-1 and SEGS-2 Episomes Are Novel DNA Satellites
