Definition
English
:
Small, linear single-stranded RNA molecules functionally acting as molecular
parasites
of certain RNA
plant viruses
.
Satellite
RNAs exhibit four characteristic traits: (1) they require
helper viruses
to replicate; (2) they are unnecessary for the replication of
helper viruses
; (3) they are encapsidated in the coat protein of the helper virus; (4) they have no extensive
sequence homology
to the helper virus. Thus they differ from
SATELLITE VIRUSES
which encode their own coat protein, and from the genomic RNA; (=RNA, VIRAL); of
satellite viruses
. (From Maramorosch,
Viroids
and Satellites, 1991, p143)
