Summary
Small RNAs (sRNAs) regulate gene expression and interact with plant hormones during stress responses. This review explores the intricate cross-regulation between sRNAs and nine key plant hormones.
Area of Science:
- Plant molecular biology
- Gene regulation
- Eukaryotic gene expression
Background:
- Small RNAs (sRNAs), including miRNAs and siRNAs, are vital regulators of gene expression in eukaryotes.
- sRNAs function through mechanisms like DNA methylation, mRNA cleavage, and translation inhibition.
- Environmental factors and plant hormones are known to influence sRNA activity.
Purpose of the Study:
- To review recent advancements in understanding the interplay between sRNAs and plant hormones.
- To elucidate the role of sRNAs in plant stress responses mediated by hormonal pathways.
Main Methods:
- Literature review of recent scientific publications.
- Synthesis of findings on sRNA biogenesis and function.
- Analysis of cross-regulatory mechanisms between sRNAs and plant hormones.
Main Results:
- sRNAs play a significant role in plant stress adaptation.
- Evidence highlights direct involvement of sRNAs in plant hormonal pathways.
- Cross-regulation exists between sRNAs and multiple plant hormones.
Conclusions:
- sRNAs are crucial components in plant hormone-mediated stress responses.
- Further research into sRNA-hormone interactions can reveal new strategies for crop improvement.
- Understanding these pathways is key to deciphering plant adaptation mechanisms.

01:25Cell Signaling in Plants
6.1K
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...

01:29Translational Regulation
447
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,...

01:56Riboswitches
9.4K
Riboswitches are non-coding mRNA domains that regulate the transcription and translation of downstream genes without the help of proteins. Riboswitches bind directly to a metabolite and can form unique stem-loop or hairpin structures in response to the amount of the metabolite present. They have two distinct regions – a metabolite-binding aptamer and an expression platform.
The aptamer has high specificity for a particular metabolite which allows riboswitches to specifically regulate...

01:23RNA Interference
27.6K
RNA interference (RNAi) is a process in which a small non-coding RNA molecule blocks the post-transcriptional expression of a gene by binding to its messenger RNA (mRNA) and preventing the protein from being translated.
This process occurs naturally in cells, often through the activity of genomically-encoded microRNAs. Researchers can take advantage of this mechanism by introducing synthetic RNAs to deactivate specific genes for research or therapeutic purposes. For example, RNAi could be used...

Overview
Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in the regulation of gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.
