Cucumovirus with a satellite-like RNA isolated from Robinia pseudacacia L.

open access: yesPeriodicum biologorum, 1997
Background and purpose: Naturally occurring cucumber mosaic Cucumovirus (CMV) and peanut stunt Cucumovirus (PSV) occasionally encapsidate satellite RNA (satRNA) along with genomic and subgenomic RNAs. CMV satRNA variants reported so far range in size from 330-405 nucleotides. PSV satRNA variants are, in average, longer (391-393 nt).
