DNA fiber replication in chromosomes of a higher plant (Pisum sativum)

Journal Article · · Exp. Cell Res.; (United States)

Techniques were developed for the autoradiographic analysis of chromosomal DNA fiber replication of higher plant cells. The DNA fibers of Pisum root meristem cells replicate via many tandemly arranged replicons. Each replicon has an initiation point and the average distance between them is about 54 ..mu..m. Most of the replicons of Pisum showed bidirectional DNA chain growth that proceeded from a commonly shared initiation point. The average rate of replication per single fork is approx. 29 ..mu..m/h at 23/sup 0/C. (auth)
