Involvement of C4 protein of beet severe curly top virus (family Geminiviridae) in virus movement. [PDF]
PLoS ONE, 2010 BACKGROUND: Beet severe curly top virus (BSCTV) is a leafhopper transmitted geminivirus with a monopartite genome. C4 proteins encoded by geminivirus play an important role in virus/plant interaction.

Replication mechanisms of circular ssDNA plant viruses and their potential implication in viral gene expression regulation [PDF]
mBio, 2023 The replication of members of the two circular single-stranded DNA (ssDNA) virus families Geminiviridae and Nanoviridae, the only ssDNA viruses infecting plants, is believed to be processed by rolling-circle replication (RCR) and recombination-dependent ...

Maize Streak Virus: Single and Gemini Capsid Architecture [PDF]
VirusesGeminiviridae are ssDNA plant viruses whose control has both economical and agricultural importance. Their capsids assemble into two distinct architectural forms: (i) a T = 1 icosahedral and (ii) a unique twinned quasi-isometric capsid.
