Strains
Anita Lardans, Boynton-Gillham laboratory, Duke University
Phenotype: requires acetate; herbicide resistant (atrazine, bromacil, metribuzin)
This strain contains a site-directed mutation A251L in the psbA gene, and a silent mutation (indicated by * in the strain name), creating an SspI site by substituting a T for a C at position 247. CC-125 wild-type cells were co-transformed with the psbA plasmid and with plasmid P-228, which confers spectinomycin resistance by a mutation in the gene encoding the chloroplast 16S ribosomal RNA.
The A251L mutation confers resistance to atrazine, bromacil and metribuzin, but not to DCMU, and results in poor photoautotrophic growth.

This strain contains a site-directed mutation A251P in the psbA gene, and a silent mutation (indicated by * in the strain name) creating an SspI site by substituting a T for a C at position 247. CC-125 wild-type cells were co-transformed with the psbA plasmid and with plasmid P-228, which confers spectinomycin resistance by a mutation in the gene encoding the chloroplast 16S ribosomal RNA.
Strains carrying the A251P mutation are indistinguishable from wild type with respect to herbicide resistance and photoautotrophic growth.

CC-125 wild-type cells were co-transformed with the psbA plasmid and with plasmid P-228, which confers spectinomycin resistance by a mutation in the gene encoding the chloroplast 16S ribosomal RNA.

This strain contains a site-directed mutation A251A in the psbA gene, and a silent mutation (indicated by * in the strain name) creating an SspI site by substituting a T for a C at position 247. CC-125 wild-type cells were co-transformed with the psbA plasmid and with plasmid P-228, which confers spectinomycin resistance by a mutation in the gene encoding the chloroplast 16S ribosomal RNA. This strain, which retains the wild-type sequence at residue 251, was used as the control for the other psbA mutants created in the same study.
