Figure 2.
The design of aminoglycoside-3′-adenyltransferase (aadA) construct for plastid transformation containing 16S rDNA promoter (from Nicotiana tabacum) and rbcL terminator signal (from Chlamydomonas reinhardtii) cloned into pUC18 vector backbone. Restriction sites are indicated. The aadA gene confers spectinomycin and/or streptomycin resistance to the transformed cells.
