N2 - An isolate of Bean yellow mosaic virus (BYMV) not transmitted by aphids (NAT) was compared with the aphid-transmissible isolate (MI) from which it was derived. For each isolate, the sequence of the coat protein and parts of the helper component was determined. A single nucleotide substitution caused a NAG to NAS alteration in the coat protein of the non aphid-transmissible isolate. Loss of aphid transmissibility in isolate BYMVMI-NAT was most likely caused by this mutation within the NAG motif. Systemic movement and accumulation of the virus in infected plants were not affected by the mutation.
