aadA
A commonly used antibiotic for Chlamydomonas chloroplasts. Confers resistance to spectinomycin and streptomycin
Usage and Biology
The aadA gene confers antibiotic resistance to Spectinomycin and Streptomycin and is functional in both chloroplasts and E. coli.
This part can be used with other level 0 Phytobrick to create a transcriptional unit to provide a selection pressure on transformations.
Previous experience with this antibiotic marker in Saul Purton's lab recommends the psaA promoter, which is a strong promoter. However, when constructing level 2 composite parts, it is advisable to use the psaA promoter for the gene of interest and place aadA under atpA promoter which is weaker.
Verification
Part verified in E. coli ligated into Paul Surton's (UCL) pASap1 backbone. These transformed bacteria grow on both ampicilin (backbone antibioti) and spectinomycin (albeit slowly). Picture below indicates growth on Spec plates (before plating on amplicilin plates to verify double resistance).
