Theses and Dissertations--Plant and Soil Sciences
The plant hormone cytokinin plays essential roles in many aspects of growth and development. The cytokinin signal is transmitted by a multistep phosphorelay to the members of two functionally antagonistic classes of Arabidopsis response regulators (ARRs): the type-B ARRs (response activators) and type-A ARRs (negative-feedback regulators). Previous studies have shown that mutations in AXR1, encoding a subunit of the E1 enzyme in the related to ubiquitin (RUB) modification pathway, leads to decreased cytokinin sensitivity. This research shows that the cytokinin resistance of axr1 seedlings is suppressed by loss-of-function of type-A ARRs and that the cytokinin resistance caused by …
