Analytical Determination of Auxins and Cytokinins

Parallel determination of auxin and cytokinin levels within plant organs and tissues represents an invaluable tool for studies of their physiological effects and mutual interactions. Thanks to their different chemical structures, auxins, cytokinins and their metabolites are often determined separately, using specialized procedures of sample purification, extraction, and quantification.

How does high concentration of auxin inhibit the primary

Auxin rapidly inhibits cell division and differentiation, and as extra auxin has little or no effect on cell differentiation, cell differentiation proceeds towards the root tip (EDFig. 6,7; Suppl videos 3 and 4).

Direct determination of plant-growth related metabolites

The detection of plant hormones and growth regulators is of great interest for many biological studies especially in the determination of metabolites related to plan growth and differentiation. In this work, we propose a simple method based on capillary electrophoresis (CE) for the separation of different classes of plant growth regulators such as auxins, cytokinins, gibberelic acid and abscisic acid.

What are plant auxins? And how do they affect plant growth?

Auxins can be produced naturally (by the plant) or synthetically (in a lab). When produced synthetically, they can be used in high concentrations as a pesticide, causing drastic growth. The herbicide, 2-4-D, is an example of an auxin-based pesticide, specifically engineered to cause dicots (plants like dandelions) to grow quickly and uncontrollably, ultimately killing the plant.

Review article Auxin biology in roots plantroot

Auxin metabolism. Plants sometimes have to decrease, instead of increasing, auxin concentration to cease the effect of auxin. The oxidation of IAA plays a major role in the decrease in auxin concentration (Östin et al. 1998, Kowalczyk and Sandberg 2001). Besides this, plants have developed other ways to eliminate active auxin.
