Descriptor ARN satélite
Scope note: Moléculas pequeñas y lineales de ARN monocatenario que actúan funcionalmente como parásitos moleculares de ciertos virus ARN de plantas. Los ARN satélite muestran cuatro rasgos característicos: 1) necesitan virus auxiliares para replicarse; 2) son innecesarios para la replicación de los virus auxiliares; 3) están encapsulados en el envoltorio proteico del virus auxiliar; 4) no tienen gran homología de secuencia con el virus auxiliar. Difieren de los VIRUS SATÉLITE que codifican su propia proteína del envoltorio, y del ARN genómico (ARN VÍRICO) de los virus satélite. (Maramorosch, Viroids and Satellites, 1991, p143)

Scope note: 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)
Annotation: RNA molecules acting as molecular parasites of various RNA plant viruses; coord IM with specific plant virus /genet (IM or NIM) but note that CUCUMBER MOSAIC VIRUS SATELLITE is available
