A Bestiary of molecular replicators.

examples	category	notes
satellite tobacco mosaic virus	satellite virus	a satellite virus encodes its own coat protein but relies on Helper for other machinery
CMV Y-sat, cucumber mosaic virus (CMV) Y satellite RNA	satellite RNAsubviral component	a satellite nucleic acid like RNA [22–24] uses Helper coat protein, may provide other non-protein machinery, e.g. siRNAs [25]
alphavirusesbetaviruses	satellite DNAsubviral components	nomenclature of newly discovered classes of replicators is in chaos, what needs/uses what/anything where/anywhere?
tobacco rattle virus comovirusesdianthoviruses	multi-component viruses, genome components separately encapsidated‘coviruses’, for short	contrast with influenza virus whose genome segments travel in same capsid original [26] shorter term, coviruses, almost [16] never usedvery common form of plant viruses
Sputnik [27]	satellite virusvirophage	virus of Mamavirus which infects amoebae
unnamed	transpovironsprovirophage	giant viruses such as mimivirus family and Pandoravirus are revealing a new bestiary of replicators [2]
sTRSV, tobacco ringspot virus	viroidviroid-likevirusoidsatellite	‘s’ prefix generically ‘satellite’, various names reflecting knowledge of relatedness, contribution of any sort to Helper virus, known requirements for components, etc. [11]
P4, Enterobacteria phage P4 [28]	satellite (bacterio)phage	depends on P2 phage
Hepatitis D virus	satellite RNAsubviral satelliteviroid-likemore?	see [29]uses coat protein of Hepatitis B virus
pea enation mosaic virus	?	insoluble ontological conundrum [30,31]
V-SINES	retropositional parasitesnon-autonomous transposable element	rather than being simply defective LINEs, V-SINEs may actively parasitize them [32]
