Developmental Switch

In multicellular organisms, a stringent control of the transition between cell division and differentiation is crucial for correct tissue and organ development. In the Arabidopsis root, the boundary between dividing and differentiating cells is positioned by the antagonistic interaction of the hormones auxin and cytokinin. Cytokinin affects polar auxin transport, but how this impacts the positional information required to establish this tissue boundary, is still unknown. By combining computational modeling with molecular genetics, we show that boundary formation is dependent on cytokinin’s control on auxin polar transport and degradation. The regulation of both processes shapes the auxin profile in a well-defined auxin minimum. This auxin minimum positions the boundary between dividing and differentiating cells, acting as a trigger for this developmental transition, thus controlling meristem size.

Synthetic Growth

Morphactin, methyl 2-chloro-9-hydroxyfluorene-9-carboxylate (IT 3456), is a synthetic growth regulator with a unique action affecting various morphogenetic and physiological processes in plants, and has been characterized as a specific inhibitor of auxin polar transport. Morphactin applied at the last internode in decapitated shoots of <em>Bryophyllum calycinum</em> substantially stimulated elongation and thickening of the internode. Benzyladenine applied alone little affected stem elongation and thickening. Simultaneous application of benzyladenine and morphactin showed a synergistic effect on thickening, while it did not on elongation. These results suggest that morphactin translocated basipetally from the top of the treated internode inhibits auxin polar transport from the internode, resulting in the accumulation of endogenous auxin for elongation and thickening in the treated internode of decapitated shoots of <em>Bryophyllum calycinum</em>.

2,4 Dichlorophenoxyacetic Acid

The transport behaviour of the synthetic auxin 2,4-dichlorophenoxyacetic acid (2,4-D), applied in aqueous solution to the cut stem surface of sunflower seedlings decapitated in the epicotyl, was studied using steam-ringing to differentiate between apoplastic and symplastic movement. Initially the 2,4-D moved in apoplastic tissue and was distributed rapidly throughout the plant, apparently as the result of a non-auxin-specific transport process. When an amount of 2,4-D sufficient to maintain apical dominance in the decapitated seedling was applied, the initially distributed material was subsequently redistributed acropetally in the stem apoplast and accumulated in the stump apex. When a lower level of 2,4-D, insufficient to maintain apical dominance, was applied, the initially distributed material was redistributed basipetally in the stem symplast, probably via the auxin polar transport system, and accumulated in the root. It is suggested that the 2,4-D loading capacity of the polar transport system is an important factor determining both the transport behaviour of the 2,4-D and its ability to maintain apical dominance in this system.
