TL;DR: The results are consistent with the hypothesis that cytokinins have central, but opposite, regulatory functions in root and shoot meristems and indicate that a fine-tuned control of catabolism plays an important role in ensuring the proper regulation of cytokinin functions.

TL;DR: The mutations identified in this study not only promote more robust shoot production in tissue culture, but also enhance green-callus and root formation, which is interpreted to mean that, in tissueculture, IRE genes act before organ specification during the time when root explants acquire the competency to respond to organ formation signals.

TL;DR: Increased zeatin O-glucosylation in detached, cytokinin-dependent tissues leads to a shift in the response to exogenous zeatIn indicative of cytokinIn sequestering, the effect can simulate a reduction or a rise in cytokin in activity depending on the tissue and stage of development.

TL;DR: Flow cytometry showed that the G1/S transition occurred regardless of the cytokinin drop, which indicates an extremely low dose requiry for that stage of the cell cycle.

TL;DR: It is proposed that increasing the cytokinin/auxin ratio may lead to tumor formation on radish crop roots.
