Summary
Post-translational modifications (PTMs) critically regulate jasmonate (JA) hormone pathways in plants. Understanding these PTMs is vital for comprehending plant development and defense mechanisms.
Area of Science:
- Plant biology
- Molecular plant science
- Biochemistry
Background:
- Jasmonate (JA) is a crucial plant hormone regulating development and defense.
- Core JA biosynthesis and signaling pathways are well-understood.
- Post-translational modifications (PTMs) are increasingly recognized as key regulators of JA signaling.
Purpose of the Study:
- To provide an overview of identified PTMs in JA pathways.
- To elucidate the mechanisms by which PTMs modulate JA responses.
- To highlight the importance of PTMs in plant hormone signaling.
Main Methods:
- Literature review of PTMs in JA biosynthesis and signaling.
- Analysis of existing research on protein modifications.
- Synthesis of current knowledge on JA pathway regulation.
Main Results:
- PTMs significantly impact protein structure and function within JA pathways.
- Various PTMs have been identified across JA biosynthesis and signaling components.
- These modifications allow for precise spatiotemporal control of JA signaling output.
Conclusions:
- PTMs are essential for fine-tuning plant responses mediated by JA.
- Dysregulation of PTMs leads to impaired plant development and defense.
- Further research into PTMs offers insights into plant hormone signaling.

Translational regulation in prokaryotes ensures efficient protein synthesis by controlling ribosome access to mRNA. This regulation is mediated by secondary RNA structures, including translational riboswitches, RNA thermometers, and small RNAs (sRNAs), which respond to intracellular and environmental signals to modulate gene expression.Translational RiboswitchesRiboswitches in the leader region of mRNAs can regulate translation by altering the accessibility of the Shine-Dalgarno (SD) sequence,...

01:23Regulation of Expression at Multiple Steps
976
The gene expression in cells is regulated at different stages: (i) transcription, (ii) RNA processing, (iii) RNA localization, and (iv) translation. Transcriptional regulation is mediated by regulatory proteins such as transcription factors, activators, or repressors—these control gene expression by initiating or inhibiting the transcription of genes. Once a precursor or pre-mRNA is produced, it undergoes post-transcriptional modification, including 5' capping, splicing, and the...

02:04Regulation of Transpiration by Stomata
28.8K
During photosynthesis, plants acquire the necessary carbon dioxide and release the produced oxygen back into the atmosphere. Openings in the epidermis of plant leaves is the site of this exchange of gasses. A single opening is called a stoma—derived from the Greek word for “mouth.” Stomata open and close in response to a variety of environmental cues.

02:24Regulation of Expression Occurs at Multiple Steps
23.0K
Gene expression can be regulated at almost every step from gene to protein. Transcription is the step that is most commonly regulated. This involves the binding of proteins to short regulatory sequences on the DNA. This association can either promote or inhibit the transcription of a gene associated with the respective sequence.
Transcription results in the generation of precursor (pre-mRNA) that consists of both exons and introns, which needs further processing before being translated to a...

01:25Cell Signaling in Plants
5.7K
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...

01:20The JAK-STAT Signaling Pathway
9.1K
Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as SH2...
