Cytokinin oxidase/dehydrogenase inhibitors stimulate 2iP to induce direct somatic embryogenesis in Coffea arabica
Somatic embryogenesis in Coffea spp. is important for mass production and genetic engineering. Coffee is an exceptional case, as somatic embryogenesis can be induced by applying a cytokinin such as 2iP as the onl...

Cytokinin Properties of Meta-Topolin and Related Compounds
6-Benzylaminopurine, meta-topolin and their derivatives have been and are being used in and tested for the micropropagation of plants using tissue culture techniques. Meta-topolin and meta-methoxy-topolin were sy...

Open AccessCytokinin fluoroprobe reveals multiple sites of cytokinin perception at plasma membrane and endoplasmic reticulum
Plant hormone cytokinins are perceived by a subfamily of sensor histidine kinases (HKs), which via a two-component phosphorelay cascade activate transcriptional responses in the nucleus. Subcellular localizati...

Characterization of five CHASE-containing histidine kinase receptors from Populus × canadensis cv. Robusta sensing isoprenoid and aromatic cytokinins
Five poplar CHASE-containing histidine kinase receptors bind cytokinins and display kinase activities. Both endogenous isoprenoid and aromatic cytokinins bind to the receptors in live cell assays.

TDZ: Mode of Action, Use and Potential in Agriculture
Strong cytokinin effects of thidiazuron (TDZ) in many plant species have been observed since its discovery in the 1970s. Several of these effects, such as cell division stimulatory activity, anti-senescence, a...

Nebularine Affects Plant Growth and Development but does not Interfere with Cytokinin Signaling
Nebularine is known for its high cytotoxicity in animals, whereas in plants it was originally believed to be an anticytokinin. In this study we show that in classical cytokinin bioassays, nebularine antagonize...
