Based on conserved regions among genomic RNA of tobamoviruses, a pair of primers spanning the sequence encoding the movement protein were synthesized. A cDNA fragment of 1700bp was thus amplified by RT-PCR(reverse transcription-polymerase chain reaction). The fragment was cloned into pGEM-T easy vector and sequenced. DNA sequence analysis showed that the fragment contained a region of 768 nucleotides encoding protein of 256 amino acid of frangipani mosaic virus (FMV) and also partial sequence corresponding to 180ku and 17. 5ku protein.
