Viral coat protein gene
were amplified by one step reverse transcription polymerase
chain reaction (RT-PCR) using Forward uni-poty primer corresponding
nucleotide position 7986-8009 in NIb gene region
(Chen et al., 2001); 50 GGX AAY AAY AGY GGX CAZ 30 (X ¼ A, G, C
or T; Y ¼ T or C; Z ¼ A or G) and reverse primer 50 CCA AGC TTT
TAC TGC GGG GAA C 30 (proximal to the C-terminal sequence of
coat protein gene of CABMV-Thai yard long bean isolate Acc. No.
U72204).
