Mosharaf N, Tabein S, Behjatnia SAA, Safi A (2019) Role of betasatellites in interaction of viruses with plants
. Plant Pathology Science 9(1):78-90. DOI: 10.2982/PPS.9.1.78.
Betasatellites, as begomovirus-dependent small circular single-stranded DNAs, are multifunctional agents that trigger disease symptoms, suppress gene silencing pathways and also interact with various cellular pathways and factors. These subviral elements have a conserved genome organization that encodes only a functional open reading frame on the complementary sense strand βC1. The encoded beta satellite protein affects only the helper begomovirus cycle factor. The small size with a strong promoter sequence and the ability to replace βC1 with foreign genes made beta satellites suspected tools for the investigation of functional genes. As we expand our knowledge of begomovirus / beta satellite complexes and their interactions with host plants, we develop management approaches for the expansion of begomoviral destructive diseases.

Abstract
Most of the plant viruses that have recently spread in tropical, subtropical and temperate regions and have limited the production of important plant products are transmitted by whiteflies. Three important whitefly species Bemisia tabaci, Trialeurodes vaporariorum and Trialeurodes abutiloneus are known as carriers of most plant viruses. Plant viruses transmitted by whiteflies are in the genera: Begomovirus, Crinivirus, Ipomovirus, Carlavirus, Torradovirus and Polerovirus. Management of whiteflies is difficult because of their wide host range, high reproduction rate, large population size, and also their resistance to insecticides, but new methods of chemical, biological control and the production of resistant transgenic plants have been developed to manage them, which are described in this article.
