title: Restriction endonuclease map of Euglena gracilis chloroplast DNA.
abstract: A physical map of the Euglena gracilis chloroplast genome has been constructed, based on cleavage sites of Euglena gracilis chloroplast DNA treated with bacterial restriction endonucleases. Covalently close, circular chloroplast DNA is cleaved by restriction endonuclease SalI into three fragments and by restriction endonuclease BamHI into six fragments. These nine cleavage sites have been ordered by fragment molecular weight analysis, double digestions, partial digestions, and by digestion studies of isolated DNA fragments. A fragment pattern of the products of EcoRI restriction endonuclease digestion of Euglena chloroplast DNA is also described. One of these fragments has been located on the cleavage site map.
