Root enhancement in cytokinin-deficient oilseed rape causes leaf mineral enrichment, increases the chlorophyll concentration under nutrient limitation and enhances the phytoremediation capacity [PDF]
BMC Plant Biology, 2019 Background Cytokinin is a negative regulator of root growth, and a reduction of the cytokinin content or signalling causes the formation a larger root system in model plants, improves their growth under drought and nutrient limitation and causes ...

Nature Communications, 2020 Cytokinin receptors predominantly localize to the endoplasmic reticulum. Here, Kubiasová et al. use a cytokinin fluoroprobe to show that ER-localized cytokinin receptors can enter the secretory pathway, reach the plasma membrane and undergo vesicular ...

Nature Communications, 2018 Cytokinin fulfills its diverse roles in planta through a series of transcriptional responses. We identify the in vivo DNA binding site profiles for three genetically redundant type-B ARABIDOPSIS RESPONSE REGULATORS (B-ARRs): ARR1, ARR10, and ARR12.

Nature Communications, 2021 Nodule development in legumes is a cytokinin dependent process. Here the authors show that high nitrate supply, which limits nodulation, suppresses cytokinin biosynthesis in Lotus japonicus which contrasts with the positive effect of nitrate on cytokinin

Quantitative live-cell imaging of auxin and cytokinin signalling in developing feeding sites of Heterodera schachtii [PDF]
Plant Signaling & BehaviorCyst nematodes are sedentary endoparasites that establish unique feeding structures (syncytia) inside their host roots. Crosstalk between auxin and cytokinin signaling is thought to play a crucial role in syncytia formation.

Cytokinin – A Developing Story [PDF]
Trends in Plant Science, 2019 In the past decade tremendous advances have been made in understanding the biosynthesis, perception, and signaling pathways of the plant hormone cytokinin. It also became clear that interfering with any of these steps greatly impacts all on stages of growth and development.

Characterization of CHARK, an unusual cytokinin receptor of rice
Scientific Reports, 2021 The signal transduction of the plant hormone cytokinin is mediated by a His-to-Asp phosphorelay. The canonical cytokinin receptor consists of an extra cytoplasmic hormone binding domain named cyclase/histidine kinase associated sensory extracellular ...

The Arabidopsis Book, 2014 Cytokinins are N (6) substituted adenine derivatives that affect many aspects of plant growth and development, including cell division, shoot initiation and growth, leaf senescence, apical dominance, sink/source relationships, nutrient uptake, phyllotaxis, and vascular, gametophyte, and embryonic development, as well as the response to biotic and ...

RETRACTED: Cytokinin and abiotic stress tolerance -What has been accomplished and the way forward?
Frontiers in Genetics, 2022 More than a half-century has passed since it was discovered that phytohormone cytokinin (CK) is essential to drive cytokinesis and proliferation in plant tissue culture.
