This work was aimed to find sequence variability between capsid and polymerase gene sequences of five RBDV samples. Capsid and polymerase cDNAs were obtained by reverse transcription and PCR (RT-PCR) of RNA extracted from plants inoculated with each of the respective isolated samples. The amplified products were cloned in pGEM-T and sequenced. The results showed that the capsid and polymerase sequences varied less than 1% among the isolated samples. These data suggested that capsid and polymerase transgenic sequences that protect against a particular RBDV sample might protect against the others.
