    • 1979 January, Douglas A. Kennedy, “Inhibition of coronavirus 229E replication by actinomycin D”, in Journal of Virology, volume 29, number 1, page 401:
      Recent biochemical studies have revealed that the single-stranded RNA of several coronaviruses is polyadenylated, indicating that it is probably of positive polarity, and the genome of infectious bronchitis virus has been reported to be infectious, supporting evidence that the coronavirion RNA has a message function.
    • 1983, Stuart Siddell, “The Biology of Coronaviruses”, in Journal of General Virology, volume 64, page 761:
      Coronavirions are pleomorphic, although generally spherical, 60 to 220 nm in diameter and bear widely spaced, club-shaped surface projections about 20 nm in length.
    • 2009 January 13, Montserrat Bárcena, “Cryo-electron tomography of mouse hepatitis virus: Insights into the structure of the coronavirion”, in PNAS, volume 106, number 2, page 582:
      Our cryo-tomograms of whole coronavirions provide direct insight into the 3D structure of CoVs, revealing important features of the virion envelope and the RNP.
