Cytokinins are a class of plant-specific hormones that play a central role during the cell cycle
and influence numerous developmental programs. Because of the lack of biosynthetic and …

We used loss-of-function mutants to study three Arabidopsis thaliana sensor histidine kinases,
AHK2, AHK3, and CRE1/AHK4, known to be cytokinin receptors. Mutant seeds had more …

Cyclin‐dependent kinases (cdk) control the cell division cycle (cdc). These kinases and
their regulators are frequently deregulated in human tumours. A potent inhibitor of cdks, …

This study investigates the consequences of endo‐ genously enhanced biosynthesis of the
plant hormone cytokinin in Arabidopsis thaliana (L.) Heynh. Tran‐ scriptional control of the …

After the discovery of kinetin (Miller et al. 1956, J. Am. Chem. Soc. 78: 1345–1350) there
was a flurry of syntheses that led to the finding of 6‐benzylaminopurine (BA), an active and …

While testing purines related to the non‐specific protein kinase inhibitors N 6 ‐dimethylaminopurine
and N 6 ‐( 2 ‐isopentenyl)adenine as potential inhibitors of the p34 cdc2 /cyclin B …

The size and activity of the shoot apical meristem is regulated by transcription factors and low
molecular mass signals, including the plant hormone cytokinin. The cytokinin status of the …

Optimizing root system architecture can overcome yield limitations in crop plants caused by
water or nutrient shortages. Classic breeding approaches are difficult because the trait is …

Cytokinins (CKs) are plant hormones affecting numerous developmental processes. Zeatin
and its derivatives are the most important group of isoprenoid CKs. Zeatin occurs as two …

This study investigated whether an increased production of the plant hormone cytokinin in
roots, the main site of its synthesis and putative signaling organ, can influence developmental …
