Summary
Long non-coding RNAs (lncRNAs) are key epigenetic regulators in plants, crucial for stress memory and adaptation. Harnessing lncRNAs offers a promising avenue for developing climate-resilient crops.
Area of Science:
- Plant Biology
- Epigenetics
- Molecular Biology
Background:
- Plants face diverse environmental stresses individually and in combination.
- Epigenetic regulation, including gene expression and stress memory, is vital for plant adaptation.
- Long non-coding RNAs (lncRNAs) are emerging as critical players in these epigenetic processes.
Purpose of the Study:
- To review the significant roles of lncRNAs in plant epigenetic responses to abiotic stresses.
- To explore the potential of lncRNAs in developing climate-resilient plants.
Main Methods:
- Literature review focusing on lncRNAs and plant stress responses.
- Analysis of lncRNA functions in epigenetic memory and gene regulation under stress.
Main Results:
- lncRNAs regulate gene expression and maintain cellular identity through mechanisms like chromatin remodeling and epigenetic switching.
- lncRNAs are involved in plant responses to various abiotic stresses by modulating target genes.
- lncRNAs contribute to stress memory, enabling plants to better encounter future stress events.
Conclusions:
- lncRNAs are integral to plant epigenetic regulation during abiotic stress.
- lncRNAs hold significant potential for enhancing crop resilience to climate change through breeding programs.

8.6K
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...

Overview
Transcription is the process of synthesizing RNA from a DNA sequence by RNA polymerase. It is the first step in producing a protein from a gene sequence. Additionally, many other proteins and regulatory sequences are involved in the proper synthesis of messenger RNA (mRNA). Regulation of transcription is responsible for the differentiation of all the different types of cells and often for the proper cellular response to environmental signals.

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...
