Project

Study of the intracellular distribution of cytokinins and their transport to vacuoles (GA16-04184S)

Cytokinin trafficking have for a long time been a subject of several theories. While the acropetal cytokinin transport is now relatively well understood complete. Since the major portion of the cytokinin receptors is locali...

Mechanisms of regulation of cytokinin content and action in plant cells (GA204/96/1424)

Cytokinins are plant hormones which play a crucial role in regulation of cell in plants. It has been proved that application of exogenous cytokinins induce of mevalonate biosynthesis (potential precursor of cytokinin side c...

A phytohormone specific b-glucosidase as a tool to investigate the subcellular compartmentation of phytohormone conjugation (ME 040)

The role of cellular compartmentation in regulation of cytokinin activity by reversible conjugation will be studied. A cytokinin-glucoside specific beta-glucosidase, targeted to various subcellular compartments, will be used to rele...
