Summary of the important primary sequences in the UPD of TMV U1 3′-UTR. (A) Sequence conserved within tobamovirus family (38). Absolutely conserved sequences are in red. (B) Sequences strongly required for replication of TMV RNA in tobacco plants and protoplasts (12, 49, 59) are in red, and those still significantly affecting replication are in orange. (C) Sequence affecting translation (38). Critical and moderately important sequences are shown in red and orange, respectively. (D) Sequence important for eEF1A binding (this study). Critical and moderately important sequences are shown in red and orange, respectively.
