Ethylene stimulates endoreduplication but inhibits cytokinesis in cucumber hypocotyl epidermis

Dan, Haruka; Imaseki, Hidemasa; Wasteneys, Geoffrey; Kazama, H


The effects of ethylene on cell division are generally considered inhibitory. In this study, we demonstrate that transient ethylene exposure, while suppressing cytokinesis, stimulates DNA synthesis. We monitored DNA synthesis and cytokinesis in the epidermis of cucumber (Cucumis sativus) hypocotyls, an organ whose post-germination development involves strictly limited cell division. During exposure to ethylene, DNA synthesis, assessed by the incorporation of the thymidine homolog...[Show more]
