Seed germination is controlled by a number of mechanisms and is necessary for the growth
and development of the embryo, resulting in the eventual production of a new plant. Under …

Plants have evolved elaborate mechanisms for sensing and responding to sub-optimal
environmental conditions. Abiotic stresses caused by these conditions trigger a wide range …

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 …

The plant hormones are a structurally unrelated collection of small molecules derived from
various essential metabolic pathways. These compounds are important regulators of plant …

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 …

Abstract Type-A Arabidopsis (Arabidopsis thaliana) response regulators (ARRs) are a family
of 10 genes that are rapidly induced by cytokinin and are highly similar to bacterial two …

Plant stem-cell pools, the source for all organs, are first established during embryogenesis. It
has been known for decades that cytokinin and auxin interact to control organ regeneration …

Cytokinins are classic plant hormones that orchestrate plant growth, development, and
physiology. They affect gene expression in target cells by activating a multistep …

Cytokinins are plant hormones that may play essential and crucial roles in various aspects of
plant growth and development. Although the functional significance of exogenous cytokinins …

A role of the plant hormone cytokinin in regulating the development and activity of
chloroplasts was described soon after its discovery as a plant growth regulator more than 50 …
