Summary
Investigating mRNA stability in wheat reveals how RNA structure influences gene regulation. Domestication altered RNA structures, affecting gene expression and offering new avenues for crop improvement.
Area of Science:
- Plant biology
- Molecular genetics
- Agricultural science
Background:
- mRNA stability is crucial for post-transcriptional gene regulation.
- Research on mRNA decay in wheat, a key crop, is limited.
- Understanding mRNA stability in polyploid wheat is vital for crop improvement.
Purpose of the Study:
- To investigate the mRNA decay landscape in durum wheat (Triticum turgidum L. ssp. durum).
- To explore subgenomic asymmetry in mRNA stability and its effect on gene expression.
- To understand the role of RNA structure and domestication in shaping mRNA stability.
Main Methods:
- Analysis of mRNA decay landscape in durum wheat.
- Investigation of 3' UTR structure and RNA structural motifs.
- Examination of single-nucleotide variations (SNVs) and their impact on mRNA stability.
Main Results:
- Identified subgenomic asymmetry in mRNA stability in durum wheat.
- Demonstrated that 3' UTR structure and homoeolog preference influence mRNA stability.
- Showed that SNVs selected during domestication alter subgenomic mRNA stability and expression.
Conclusions:
- Non-coding region structures play a regulatory role in mRNA stability in polyploid wheat.
- Domestication has shaped RNA structure, leading to altered subgenomic mRNA stability.
- RNA structure-mediated regulation offers potential for wheat crop improvement.

33.3K
Intact DNA strands can be found in fossils, while scientists sometimes struggle to keep RNA intact under laboratory conditions. The structural variations between RNA and DNA underlie the differences in their stability and longevity. Because DNA is double-stranded, it is inherently more stable. The single-stranded structure of RNA is less stable but also more flexible and can form weak internal bonds. Additionally, most RNAs in the cell are relatively short, while DNA can be up to 250 million...

02:51mRNA Stability and Gene Expression
5.5K
The structure and stability of mRNA molecules regulates gene expression, as mRNAs are a key step in the pathway from gene to protein. In eukaryotes, the half-life of mRNA varies from a few minutes up to several days. mRNA stability is essential in growth and development. The absence of the proteins regulating its stability, such as tristetraprolin in mice, can cause systemic issues, including bone marrow overgrowth, inflammation, and autoimmunity.

02:41Chromatin Structure Regulates pre-mRNA Processing
6.9K
In eukaryotic cells, nascent mRNA transcripts need to undergo many post-transcriptional modifications to reach the cell cytoplasm and translate into functional proteins. For a long time, transcription and pre-mRNA processing were considered two independent events that occur sequentially in the cell. However, it has now been well established that transcription and pre-mRNA processing are two simultaneous processes that are precisely regulated inside the cell.

The basic structure of RNA consists of a string of ribonucleotides attached by phosphodiester bonds. Although most RNA is single-stranded, it can form complex secondary and tertiary structures. Such structures play essential roles in the regulation of transcription and translation.

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,...

02:31Nuclear Export of mRNA
7.6K
Before mRNAs are exported to the cytoplasm, it is crucial to check each mRNA for structural and functional integrity. Eukaryotic cells use several different mechanisms, collectively known as mRNA surveillance, to look for irregularities in mRNAs. Irregular or aberrant mRNA are rapidly degraded by various enzymes. If a defective mRNA escapes the surveillance, it would be translated into a protein which would either be non-functional or not function properly. One of the primary irregularities in...
