This component had the same coat protein composition, serological properties, size and outward aspect of particles as the rest of the virus and encapsidated a molecule of RNA-2, thus exhibiting all major characteristics of the middle (M) component of nepoviruses. One of the virus isolates under study, as well as two functional RNA species, appeared to possess a third satellite-like RNA with mol. wt. 0.45 × 106., UL https://www.microbiologyresearch.org/content/journal/jgv/10.1099/0022-1317-59-1-169
