2.3. Plasmid vectors
Two plasmids were used, i.e., pAB6, that contains gus and
bar genes [28] and pAHC17 that contains the ubi promoter
[7]. In addition, plasmid pH1 that contains the ORF of
BBTV-G-cp, constructed by Molecular Plant Pathogenesis
Laboratory (MPPL), AGERI, ARC, Giza, Egypt was also
applied.
