Add 100 mg of trans-Zeatin riboside to a 100 ml volumetric flask and Add 5-20 ml of 1M NaOH (1M KOH) to dissolve the powder.
Stock solutions may be stored at -20°C for up to 6 months.
Zeatin Riboside is the most active and ubiquitous form of the naturally occurring cytokinins. Cytokinins promote cell division, stimulate shoot proliferation, inhibit root formation, slow the aging process, and activate gene expression and metabolic activity in general. In mature plants, natural cytokinin hormone levels are high during maximum growth periods. Concentrations of cytokinin used for horticulture vary between 0.1 to 10 mg/L.
The plant hormones cytokinins (CKs) comprise a class of growth regulators involved in the stress response, senescence, photosynthesis, nutrient assimilation and mobilization, as well as modulation of a plant tissue’s ability to act as a sink or source of metabolites.
CKs are recognized by a subset of sensor histidine kinases (HKs) and the signal is transmitted to the nucleus via a multistep phosphorelay (MSP), thus activating the expression of target genes.
