Viroids and viroid-like satellite RNAs: a phylogenetic analysis
1Department of Botany, University of Maryland, College Park.
Abstract:
With the discovery that certain RNAs possess catalytic properties (Kruger et al., 1982; Guerrier-Takada et al., 1983), the possible significance of certain small plant pathogenic RNAs, namely viroids and viroid-like satellite RNAs, as relics of precellular evolution deserves consideration. As a first step in this endeavor, I report here the results of a phylogenetic study of the computer-aligned nucleotide sequences of these RNAs that is based on the parsimony principle (Felsenstein and Sober, 1986).
