Insert = 2.2 kb Eco-Kpn fragment from P-322 containing 5th exon of psbA, ligated to 1.4 kb Kpn-Sal fragment from P-14 (Sal site located in BSKS polylinker) containing 5S rRNA gene and small exon of 23S rRNA gene. Resulting construct has Kpn fragments between psbA and 5S rRNA deleted as in P-320, but has wild type (erythromycin sensitive) 23S gene derived from P-14.
The DCMU-4 mutation in 5th exon of C. reinhardtii psbA gene causes a ser -> ala change at aa 264 of D1 protein, conferring resistance to DCMU and atrazine.
