Summary
Gene body methylation (gbM) in plants, an epigenetic mark, may be shaped by adaptation. While its precise function and causal link to gene expression are debated, evidence suggests gbM is influenced by natural selection.
Area of Science:
- Epigenetics
- Plant Biology
- Genomics
Background:
- Gene body methylation (gbM) involves CG methylation in plant gene exons.
- This epigenetic mark is transgenerationally inherited, suggesting a role in adaptation.
- The functional significance of gbM in plant phenotypes remains a subject of debate.
Purpose of the Study:
- To review current knowledge on plant gbM mechanisms, evolution, and function.
- To explore potential selective pressures acting on gbM.
- To analyze the relationship between gbM and gene expression patterns.
Main Methods:
- Review of existing literature on gbM establishment and maintenance.
- Analysis of gbM's evolutionary aspects and potential selective pressures.
- Novel analyses to assess gbM's effect on plant transcripts and gene expression.
Main Results:
- gbM is established and maintained through specific mechanisms in plants.
- A correlation between gbM and gene expression levels/patterns is observed.
- Evidence suggests gbM is shaped by natural selection, despite potentially small phenotypic effects.
Conclusions:
- gbM's role in plant adaptation warrants further investigation.
- The functional impact of gbM on phenotypes may be subtle but significant.
- gbM contributes to understanding adaptive mechanisms in plants.

01:37Epigenetic Regulation
3.2K
Epigenetic changes alter the physical structure of the DNA without changing the genetic sequence and often regulate whether genes are turned on or off. This regulation ensures that each cell produces only proteins necessary for its function. For example, proteins that promote bone growth are not produced in muscle cells. Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.

In 1928, a German botanist Emil Heitz observed the moss nuclei with a DNA binding dye. He observed that while some chromatin regions decondense and spread out in the interphase nucleus, others do not. He termed them euchromatin and heterochromatin, respectively. He proposed that the heterochromatin regions reflect a functionally inactive state of the genome. It was later confirmed that heterochromatin is transcriptionally repressed, and euchromatin is transcriptionally active chromatin.

02:30Genomic Imprinting and Inheritance
35.4K
Diploid organisms inherit genetic material through chromosomes from both parents. Copies of the same gene are known as alleles. In most cases, both alleles are simultaneously expressed and allow various cellular processes to function optimally. If one of the alleles is missing or mutated, the expression of the other allele can compensate; however, this is not true for all genes.

03:17Inheritance of Chromatin Structures
6.7K
Epigenetics is the study of inherited changes in a cell's phenotype without changing the DNA sequences. It provides a form of memory for the differential gene expression pattern to maintain cell lineage, position-effect variegation, dosage compensation, and maintenance of chromatin structures such as telomeres and centromeres. For example, the structure and location of the centromere on chromosomes are epigenetically inherited. Its functionality is not dictated or ensured by the underlying...

02:35Chromatin Position Affects Gene Expression
23.8K
Chromatin is the massive complex of DNA and proteins packaged inside the nucleus. The complexity of chromatin folding and how it is packaged inside the nucleus greatly influences access to genetic information. Generally, the nucleus' periphery is considered transcriptionally repressive, while the cell's interior is considered a transcriptionally active area.

01:25Cell Signaling in Plants
5.8K
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...
