Nuclear proteins and the release from quiescence of root meristematic cells in Pisum sativum

Chiatante, D.
Chromatin comprises DNA highly compacted with many proteins, and both transcription and replication processes depend on the molecular mechanisms which are able to modify this structural organization. The state of chromatin compaction is very high in cells of dry embryos and decreases with the imbibition which takes place during the first phase of germination. The structural nuclear proteins and the enzymes involved in DNA metabolism play an important role in these variations, therefore they might control the release from the quiescence of cells during germination. QP47 is a novel nonhistone nuclear protein which seems to have a structural role similar to that of H1. The variation of content of this protein could influence the accessibility of DNA.
