lncRNA - Long Non-coding RNAs02:39

lncRNA - Long Non-coding RNAs

9.8K
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...

Inheritance of Chromatin Structures

7.2K
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...

Chromatin Structure Regulates pre-mRNA Processing

8.1K
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 chromatin structure, especially...

Chromatin Position Affects Gene Expression02:35

Chromatin Position Affects Gene Expression

24.6K
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.

The 3-dimensional positioning of chromatin in the nucleus influences the...

Area of Science:

  • Molecular Biology
  • Genetics
  • Plant Science

Background:

  • Long non-coding RNAs (lncRNAs) are key regulators of gene expression, extending beyond the protein-coding paradigm.
  • lncRNAs are involved in diverse regulatory processes like epigenetic modifications, chromatin organization, and transcriptional/post-transcriptional control.
  • These molecules are crucial for modulating plant plasticity in response to environmental stimuli.

Purpose of the Study:

  • To review the current understanding of lncRNAs in shaping plant chromatin conformation.
  • To explore the mechanisms of action and functional relevance of lncRNAs in plant development and environmental responses.
  • To integrate findings within a broader cross-kingdom context, including other eukaryotic systems.

Main Methods:

  • Literature review of studies on lncRNA functions in chromatin organization.
  • Analysis of lncRNA mechanisms in plant development and environmental responses.
  • Comparative analysis with lncRNA roles in other eukaryotic systems.

Main Results:

  • lncRNAs play significant roles in regulating the three-dimensional structure of plant chromatin.
  • lncRNAs influence gene expression through epigenetic, transcriptional, and post-transcriptional mechanisms.
  • Understanding lncRNA functions provides insights into plant plasticity and cross-kingdom regulatory principles.

Conclusions:

  • lncRNAs are critical for chromatin organization and gene regulation in plants.
  • lncRNAs are essential for plant adaptation to environmental changes.
  • Cross-kingdom comparisons highlight conserved and divergent roles of lncRNAs in eukaryotes.
