Cytokinin, Biosynthesis, Receptor, Signal transduction, Molecular regulationCytokinins are master regulators of plant growth and development. They are involved in the regulation in many important physiological and metabolism processes. It is always the most important topic to investigate the cytokinin ...
N fertilizer can promote cytokinin biosynthesis/signalling and stimulates rice to produce more tillers65,66. There is evidence to suggest that exogenous application of N fertilizer can promote cytokinin biosynthesis67 and stimulate lateral bud outgrowth68. In Arabidopsis, the expression of AtIPT3 and ...
The last decade has seen the key steps in cytokinin biosynthesis, metabolism, and signal transduction elucidated at the molecular level [23]. The bioactive cytokinin concentration is regulated by several multigene families, including isopentenyl transferases (IPT) for cytokinin biosynthesis, cytokinin oxid...
Together, auxin and cytokinin regulate many of the processes that are critical to plant growth, development, and environmental responsiveness. We have previously shown that exogenous auxin regulates cytokinin biosynthesis in Arabidopsis thaliana. In this work, we show that, conversely, the application or...

which differs from profile 3 by its sustained increase in expression through the mature embryo stage, processes related to fatty acid metabolism were clearly over-represented, but other mechanisms, such as those related to polarized growth, chromatin organization and fine regulation of cytokinin, were...

Cytokinin and auxin inhibit abscisic acid-induced stomatal closure by enhancing ethylene production in Arabidopsis stomatal closure through the modulation of ethylene biosynthesis, and that ethylene inhibits the ABA-induced reduction of osmotic pressure in the guard cells...

Here, we provide evidence that deficiency in phytochrome chromophore biosynthesis impacts plastid biogenesis and sugar metabolism via coordinated alterations in auxin and cytokinin signaling in both pericarp and columella tissues. The upregulation of genes encoding phytochrome apoproteins in the columella was...
