Studies of chloroplast development in Euglena. XI. Radioautographic localization of chloroplast DNA.
Considerable evidence exists which is consistent with the picture that the chloroplast system of E1uglcna is unider autonomous genietic control. This includes studies of ultraviolet inactivationi anid photoreactivation of chloroplast inheritanice (7, 10. 13, 14) and the demonlstration of a unique species of chloroplast-associated DNA (3, 4, s5, 9, 11). Evidence has been presented for distinct c...
متن کاملStudies on Chloroplast Development and Replication in Euglena
When Euglena gracilis is grown under vitamin B(12) deficiency conditions, the amount of protein and of chlorophyll per cell increase with decrease of B(12) in the medium and consequently in the cell. The increase in cell protein is proportional to and precedes an increase in the number of chloroplasts per cell. This replication of the chloroplasts under deficiency conditions is not accompanied ...
متن کاملComplete sequence of Euglena gracilis chloroplast DNA.
We report the complete DNA sequence of the Euglena gracilis, Pringsheim strain Z chloroplast genome. This circular DNA is 143,170 bp, counting only one copy of a 54 bp tandem repeat sequence that is present in variable copy number within a single culture. The overall organization of the genome involves a tandem array of three complete and one partial ribosomal RNA operons, and a large single co...

متن کاملCircular chloroplast DNA from Euglena gracilis.
Chloroplast DNA of the protozoan flagellate, Euglena gracilis, exists as circular molecules, 40 mum in contour length, as shown by electron microscopy and buoyant density analyses.
