Summary
This study reveals the evolutionary history of N6-methyladenosine (m6A) regulators across 65 plant species. It shows conserved functions but unique structures and relaxed selection in higher plants, suggesting novel roles.
Area of Science:
- Molecular Biology
- Evolutionary Biology
- Plant Science
Background:
- N6-methyladenosine (m6A) is a crucial reversible RNA modification involved in numerous biological processes.
- While m6A regulators (writers, erasers, readers) are known, their evolutionary trajectories remain poorly understood.
Purpose of the Study:
- To systematically investigate the evolutionary patterns of m6A modification regulators in plants.
- To analyze phylogenetic relationships, sequence structure, selection pressure, and codon usage of these regulators across diverse species.
Main Methods:
- Identification of 1592 m6A regulators from 65 representative plant species.
- Phylogenetic analysis to discern evolutionary relationships.
- Comparative analysis of gene structure, motif organization, selection pressure, and codon usage.
Main Results:
- Phylogenetic trees distinguished regulators from different species and subfamilies.
- Conserved gene structures were observed within regulator types, yet unique exon/intron and motif organizations existed across families.
- Regulators primarily underwent purifying selection, with more relaxed pressure in higher plants, suggesting potential functional innovation.
Conclusions:
- The study provides a comprehensive evolutionary framework for m6A regulators in plants.
- Evolutionary divergence in m6A regulators, particularly in higher plants, may contribute to functional diversification.

RNA Editing
9.2K
RNA editing is a post-transcriptional modification where a precursor mRNA (pre-mRNA) nucleotide sequence is changed by base insertion, deletion, or modification. The extent of RNA editing varies from a few hundred bases, in mitochondrial DNA of trypanosomes, to a just single base, in nuclear genes of mammals. Even a single base change in the pre-mRNA can convert a codon for one amino acid into the codon for another amino acid or a stop codon. This type of re-coding can significantly affect the...

RNA Stability
34.1K
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...

Riboswitches
8.8K
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...

Regulation of Expression at Multiple Steps
1.1K
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...

Regulation of Expression Occurs at Multiple Steps
23.8K
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...

Biosynthesis of Nucleic Acids
285
Nucleic acid biosynthesis is a fundamental biochemical process that produces the purine and pyrimidine nucleotides essential for DNA and RNA synthesis. This pathway maintains a balanced nucleotide pool, preventing imbalances that could jeopardize genetic integrity and cellular function. Given the crucial role of nucleotides, their synthesis is tightly regulated to ensure proper cellular homeostasis.Purine BiosynthesisThe biosynthesis of purine nucleotides begins with ribose-5-phosphate, a...
