Description
| - Mutual interactions of cytokinins and auxins were identified as a major morphogenetic factor in plants. Molecular mechanisms are still largely unknown. Hypocotyls derived from ethiolated seedlings were affected by various concentration ratios of exogenous auxins and cytokinins. We analysed a role of both phytohormones in an ability of hypocotyl explants to form calli, SAM- and/or RAM-like structures. We applied two auxins, NAA and 2,4-D, differing in the mechanism of their intercellular transport, and auxin transport inhibitor NPA. WUS::NLS-GUS and CLV3::NLS-GUS marker lines were used to recognize the identity of newly formed organs and the role of both phytohormones in the regulation of the cytokinin-to-auxin ratio-dependent developmental switch. Changes in endogenous hormone maxima and position-specific hormone-dependent mitotic cell activity were studied. Suggested model of the cytokinin and auxin interactions during de novo organogenesis in Arabidopsis thaliana will be presented.
