The nucleotide sequence of lilac ring motile ilarvirus (LRMV) RNA 3 consists of 2287 nucleotides and contains two open reading frames (ORF). The first encodes a putative translation product of 285 amino acids (M r 31308) and the second encodes a putative translation product of 206 amino acids (M r 22 751). The 3' terminal nucleotides can be folded into a loop structure similar to models proposed for other ilarviruses, although the last four nucleotides are UCGC not AUGC. The absence of the terminal AUGC motif in both LRMV and two isolates of apple mosaic ilarvirus (ApMV) provides circumstantial evidence which confirms the importance of AUGC motifs upstream of the terminal AUGC in the protein binding function associated with these models. Although the 3' terminal structure of LRMV exhibits similarities to that of ApMV, comparison of the putative translation products of the two ORFs with similar products for other ilarviruses showed greatest identity with citrus leaf rugose (CiLRV) and citrus variegation (CW) ilarviruses both of which are members of subgroup 2 of this genus. Thus it is proposed that LRMV be reassigned to subgroup 2 rather than remaining in its current subgroup, 7, or being reassigned to subgroup 3 which contains ApMV. Lilac ring mottle virus (LRMV) was first described and characterized by van der Meer et al. (1976). It shares some of the properties of the members of the genus Ilarvirus, namely: four RNAs with M r values of 1.2, 1" 1, 0-9 and 0-4x 10 ~ and irregularly shaped isometric particles with some heterogeneity in size. The virus is strongly immunogenic but in serological tests did not exhibit any relationship with prunus necrotic ringspot (PNRSV), tobacco streak (TSV), elm mottle (EMV) and apple mosaic (ApMV) ilarviruses (van der Meer & Huttinga, 1979). Zuidema & Jaspars (1984) have proposed a model for the secondary structure of the 3' terminal regions of TSV and the closely related alfalfa mosaic virus (A1MV). In this model, hairpin (stem-loop) structures are stabilized by the presence of AUGC motifs with the terminal four nucleotides being AUGC. This secondary structure was proposed as being involved in the 'genome activation' common to both ilarviruses and A1MV in which the presence of either RNA 4 or the coat protein of the virus is required to initiate infection (van Vloten-Doting, 1975). In a subsequent report the 97 nucleotides at the 3'
