Isolation, characterization and expression of cyclin and cyclin-dependent kinase genes in Jerusalem artichoke (Helianthus tuberosus L.)
Tuber explants of Jerusalem artichoke (Helianthus tuberosus L.) are a model system for cell-cycle re-entry from a quiescent state, involving the activation of division of tuber parenchyma cells in response to exogenous auxin. To enable molecular studies of this system, two cyclin (Heltu;CYCD1;1 and...

| Zusammenfassung: | Tuber explants of Jerusalem artichoke (Helianthus tuberosus L.) are a model system for cell-cycle re-entry from a quiescent state, involving the activation of division of tuber parenchyma cells in response to exogenous auxin. To enable molecular studies of this system, two cyclin (Heltu;CYCD1;1 and Heltu; CYCD3;1) and two cyclin-dependent kinase (Heltu; CDKA;1 and Heltu;CDKB1;1) genes have been isolated from a Jerusalem artichoke cDNA library and their expression demonstrated during the activation of cell division. It was found that CDKA;1 transcripts are present in quiescent tubers, whereas CYCD1;1, CYCD3;1 and CDKB1;1 transcripts are induced during cell-cycle re-entry as well as during bud growth of whole tubers. Both CYCD1;1 and CYCD3;1 transcripts appear shortly before, or coincident with, the onset of S phase |
