Summary
This review explores microRNAs (miRNAs) regulating plant lignan biosynthesis. Understanding these miRNA-based mechanisms is crucial for improving lignan production and their health benefits.
Area of Science:
- Plant biochemistry
- Molecular biology
- Metabolomics
Background:
- Lignans are plant secondary metabolites with significant health benefits.
- Their biosynthesis occurs via the phenylpropanoid pathway.
- MicroRNAs (miRNAs) are known regulators of secondary metabolite production.
Purpose of the Study:
- To systematically review miRNA-mediated regulation of lignan biosynthesis.
- To consolidate current knowledge on genetic and regulatory mechanisms.
- To highlight knowledge gaps and future research directions.
Main Methods:
- Literature review of existing studies on lignan biosynthesis and miRNA regulation.
- Analysis of known genes, enzymes, and transcription factors in the lignan pathway.
- Synthesis of information to propose a regulatory model.
Main Results:
- The genetic basis of lignan biosynthesis is well-established.
- While miRNA roles in other secondary metabolites are known, their specific role in lignan biosynthesis requires systematic review.
- A regulatory mosaic of potential miRNA targets in lignan pathways is proposed.
Conclusions:
- MicroRNAs play a significant, yet under-explored, role in regulating plant lignan biosynthesis.
- Further research is needed to functionally identify miRNAs involved in this process.
- Understanding these regulatory networks can enhance lignan production for nutritional benefits.

01:22MicroRNAs
21.5K
MicroRNA (miRNA) are short, regulatory RNA transcribed from introns—non-coding regions of a gene—or intergenic regions—stretches of DNA present between genes. Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After...

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...

02:39lncRNA - Long Non-coding RNAs
8.8K
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...

01:56Riboswitches
8.4K
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...

01:02Role of Microtubules in Cell Wall Deposition
2.5K
Microtubules are small hollow tubes in eukaryotic cells. The cell wall microtubules are polymerized dimers of two globular proteins, α-tubulin and β-tubulin, two globular proteins. With a diameter of about 25 nm, microtubules are the widest components of the cytoskeleton. They help the cell resist compression and provide a track along which vesicles move through the cell or pull replicated chromosomes to opposite ends of a dividing cell. Microtubules go through quick cycles of...

The plant cell wall gives plant cells shape, support, and protection. As a cell matures, its cell wall specializes according to the cell type. For example, the parenchyma cells of leaves possess only a thin, primary cell wall.
