RNA silencing is the primary immune response against geminivirus infection.<\/span><\/p>\n

Betasatellites associated with the geminivirus\u2013betasatellite disease complex encode a suppressor to antagonize both the transcriptional gene silencing and post-transcriptional gene silencing pathways.<\/span><\/p>\n

Protein post-translational modifications, such as phosphorylation and ubiquitination, may contribute to anti-geminiviral immunity, which is sometimes hijacked by the betasatellite to facilitate infection.<\/span><\/p>\n

Autophagy has been found to be an effective anti-geminiviral immune response both in plants and in the transmission vector whitefly.<\/span><\/p>\n

The betasatellite induces the autophagy pathway to downregulate key components of the plant RNA silencing pathway to promote geminivirus infection.<\/span><\/p>\n

Betasatellites are a diverse group of circular single-stranded DNA satellites frequently associated with begomoviruses belonging to the family  <\/span>Geminiviridae.<\/span> Challenged with a geminivirus\u2013betasatellite infection, plants have employed sophisticated defense mechanisms to protect themselves. Betasatellites, in turn, employ mechanisms to antagonize these plant antiviral pathways. In this review, we focus on the anti-geminiviral immune pathways present both in plants and whiteflies. We also outline the counter-defensive strategies deployed by betasatellites to overcome the host defenses and initiate a successful infection. Finally, we discuss the outcomes of the opposing forces of plant immunity and betasatellite-mediated antagonism in the context of an evolutionary arms race. Understanding of the molecular dialog between plants and betasatellites will likely allow for the development of novel antiviral strategies<\/span><\/p>\n
