Complete 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.
متن کاملAction of Nalidixic Acid on Chloroplast Replication in Euglena gracilis.
The role of light in nalidixic acid bleaching of Euglena gracilis var. bacillaris was investigated. The kinetics of loss of the chloroplast-associated DNA and the sensitivity of chloroplast replication to ultraviolet light was followed during treatment with nalidixic acid. By using the mutant P(4)ZUL, and 3-(3,4-dichlorophenyl)-, 1-dimethylurea, it was demonstrated that the requirement for ligh...
متن کاملUltraviolet Inactivation of Chloroplast Formation in Synchronously Dividing Euglena Gracilis.
Ultraviolet inactivation of chloroplast formation was studied in synchronously dividing cultures of Euglena gracilis. Sensitivity to sublethal doses given at intervals throughout the cell cycle was greater just before cell division than during division. There was approximately a twofold difference in the doseresponse relationships for the periods of high and low sensitivity.
متن کاملInfluence of growth conditions upon the number of chloroplast DNA molecules in Euglena gracilis.
The number of chloroplast DNA molecules in Euglena gracilis cells was measured by determining the shift in the observed second-order rate constant for the reassociation of (125)I-labeled chloroplast DNA in the presence of unlabeled total cell DNA. Cells grown to stationary phase in the dark contained 217 molecules of chloroplast DNA. Cells grown to stationary phase in the light in either hetero...
