Auxins and Cytokinins Regulate Phytohormone Homeostasis and Thiol-Mediated Detoxification in the Green Alga Acutodesmus obliquus Exposed to Lead Stress

open access: yesScientific Reports, 2020
Phytohormones, such as auxins and cytokinins, take part in the integration of growth control and stress response, but their role in algal adaptation to heavy metal remains to be elucidated.

Naturally Occurring and Artificial N9-Cytokinin Conjugates: From Synthesis to Biological Activity and Back

open access: yesBiomolecules, 2020
Cytokinins and their sugar or non-sugar conjugates are very active growth-promoting factors in plants, although they occur at very low concentrations. These compounds have been identified in numerous plant species.

The effects of rising atmospheric carbon dioxide on shoot-root nitrogen and water signaling. [PDF]

open access: yes, 2013
Terrestrial higher plants are composed of roots and shoots, distinct organs that conduct complementary functions in dissimilar environments. For example, roots are responsible for acquiring water and nutrients such as inorganic nitrogen from the soil ...

Phenotypic, Transcriptomic, and Metabolomic Signatures of Root-Specifically Overexpressed OsCKX2 in Rice

open access: yesFrontiers in Plant Science, 2021
Cytokinins are crucial signaling molecules that regulate plant growth and development. OsCKX2 irreversibly degrades nucleobase cytokinins by encoding cytokinin oxidase/dehydrogenase to control grain production in rice.

Strigolactones as an auxiliary hormonal defence mechanism against leafy gall syndrome in Arabidopsis thaliana [PDF]

open access: yes, 2015
Leafy gall syndrome is the consequence of modified plant development in response to a mixture of cytokinins secreted by the biotrophic actinomycete Rhodococcus fascians. The similarity of the induced symptoms with the phenotype of plant mutants defective

Cytokinin Regulation of Source-Sink Relationships in Plant-Pathogen Interactions

open access: yesFrontiers in Plant Science, 2021
Cytokinins are plant hormones known for their role in mediating plant growth. First discovered for their ability to promote cell division, this class of hormones is now associated with many other cellular and physiological functions.

Environmental, developmental, and genetic factors controlling root system architecture [PDF]

open access: yes, 2014
A better understanding of the development and architecture of roots is essential to develop strategies to increase crop yield and optimize agricultural land use.

Cytokinins beyond plants: synthesis by Mycobacterium tuberculosis

open access: yesMicrobial Cell, 2015
Mycobacterium tuberculosis (M. tuberculosis) resides mainly inside macrophages, which produce nitric oxide (NO) to combat microbial infections. Earlier studies revealed that proteasome-associated genes are required for M.

Biochemical and Structural Aspects of Cytokinin Biosynthesis and Degradation in Bacteria

open access: yesMicroorganisms, 2021
It has been known for quite some time that cytokinins, hormones typical of plants, are also produced and metabolized in bacteria. Most bacteria can only form the tRNA-bound cytokinins, but there are examples of plant-associated bacteria, both pathogenic ...

Strigolactones spatially influence lateral root development through the cytokinin signaling network [PDF]

open access: yes, 2015
Strigolactones are important rhizosphere signals that act as phytohormones and have multiple functions, including modulation of lateral root (LR) development.
