Antioxidants & Redox Signaling
|November 5, 2013
Summary
Plant growth is controlled by a redox signaling hub interacting with phytohormone networks. This framework explains how plants maximize productivity in ideal conditions and alter development under stress.
Area of Science:
- Plant Biology
- Molecular Signaling
Background:
- Cellular oxidation is vital for regulating plant growth and stress responses.
- Oxidative signals and redox cycles activate cell cycles and genetic/epigenetic controls for growth and differentiation.
Purpose of the Study:
- To provide a conceptual framework for redox and phytohormone signaling in plant growth and development.
- To elucidate the interplay between cellular redox and phytohormone networks.
Main Methods:
- Focus on redox-dependent processes controlling root growth and bud burst.
- Review of accumulating evidence on phytohormone and redox controls.
Main Results:
- The redox signaling hub directly interfaces with the phytohormone network for synergistic growth control.
- This interaction modulates plant growth and development in response to environmental stress.
Conclusions:
- Reactive oxygen species have multiple roles in plant growth and development.
- Emphasis on redox-regulated proteins and reductants (e.g., NAD(P)H, thioredoxins, glutathione) is crucial for crop plant vigor and agricultural applications.

Redox reactions are vital biochemical processes that underpin energy metabolism in cells. These reactions involve the transfer of electrons between molecules, occurring in tandem as oxidation and reduction. Oxidation refers to the loss of electrons, while reduction denotes their gain. This coupling ensures the seamless flow of electrons through metabolic pathways. For example, in bacterial metabolism, glucose undergoes oxidation to carbon dioxide, while oxygen is simultaneously reduced to...

Oxidation-reduction or redox reactions involve the transfer of electrons from one molecule or atom to another. When an atom gains an electron, another atom must lose an electron, meaning oxidation and reduction must occur together. Since the redox occurs in pairs, the atom that gets oxidized is also called the reducing agent or reductant, and the atom that is reduced is also called the oxidizing agent or oxidant. A straightforward way to remember the definitions of oxidation and reduction is...

4.6K
Plant cells communicate to coordinate their cycle of growth, flowering and fruiting, and activities in roots, shoots, and leaves in response to the changing environmental conditions. Plant signaling is distinct from animal signaling. Plants primarily utilize enzyme-linked receptors, whereas the largest class of cell-surface receptors in animals are G-protein coupled receptors (GPCRs). Unlike animals, receptor tyrosine kinases are rare in plants. Instead, plants have a diverse class of...

01:23Redox Equilibria: Overview
1.4K
A reduction-oxidation reaction is commonly called a redox reaction. In a redox reaction, electrons are transferred from one species to another rather than being shared between or among atoms. The reducing agent or reductant is the species that loses electrons and gets oxidized in the process. The species that gains electrons and gets reduced in the process is the oxidizing agent or oxidant. Redox reactions are represented as two separate equations called half-reactions, where one equation...
