DNA REPLICATION AND SYNTHESIS OF DNABINDING PROTEINS IN THE CHLOROPLASTS OF A CALLUS CULTURE
Continuous labelling of callus with H-thymidine results in intermittent peaks of H-DNA per chloroplast, showing synchrony of division. The increase in H-DNA could be due to several replication rounds, and the drop to successive plastid divisions without intervening DNA synthesis. The level of DNA-binding proteins in the chloroplast parallels the peaks of plastidal DNA synthesis; such pro...
متن کاملReplication: DNA Building Block Synthesis On Demand
Correct regulation of DNA nucleotide biosynthesis is emerging as a key issue of importance for genome integrity. The fission yeast Spd1 protein can modulate the activity of ribonucleotide reductase (RNR) by at least three different mechanisms. Now a paper reports that Spd1 turnover is linked to ongoing DNA synthesis.

متن کاملChloroplast replication and chloroplast DNA synthesis in spinach leaves
Cultured leaf disks from young spinach leaves have been used to study chloroplast DNA synthesis in relation to chloroplast growth and repli cation. Autoradiographs prepared from thin sections show th a t labelling throughout disks is uniform. We consider th a t cultured leaf disks serve as a model system for studies of cell expansion and chloroplast replication during the development of spinac...
