Restriction endonuclease digestion and Southern blotting procedure were used to determine differences between extrachromosomal, nuclear, plastid, and mitochondrial DNAs from meristematic cells of cultured pea roots.Extrachromosomal and nuclear DNA ar

Experiments with cultured pea roots were conducted to determine (i) whether extrachromosomal DNA was produced by cells in the late S phase or in the G2 phase of the cell cycle, (ii) whether the maturation of nascent DNA replicated by these cells achi

Explants of stelar and cortical mature pea root tissues were cultured on solid agar synthetic medium for up to 6 d. On the 3rd and 6th day the tissue was pulsed with 3H-thymidine from 15 up to 180 min to label the DNA. Subsequently the nuclei were is

Velocity sedimentation in an alkaline sucrose gradient of newly replicated chromosomal DNA revealed the presence of extrachromosomal DNA that was not replicated by differentiating cells in the elongation zone. The extrachromosomal DNA had a number av

Replicon-size estimations from DNA fiber autoradiograms must always be considered with the limits of resolution in mind. However, data from yeast obtained by autoradiography and electron-microscopy gave similar average sizes in the 20 to 30 ..mu..m r

Analysis of the replicon properties and the cell cycle ofArabidopsis thaliana (col.) at 22° C were performed via autoradiography of isolated chromosomal DNA fibers and single cells of seedlings. The cell cycle was 8.5 h and G1, S, and G2+1/2 M were

In synchronized root cells of Pisum sativum (cv. Alaska) the joining of nascent replicons is delayed until cells reach the S-G(2) boundary or early G(2) phase. To determine if the delayed ligation of nascent chains occurs at specific termination site

Chromosomal DNA fiber autoradiography was used to examine the replicon properties of root-tip meristem cells of Helianthus annuus intact seedlings grown at temperatures from 10 to 38° C and those of root-tip cells grown in vitro at 23°. The average
