Summary
Researchers identified 1861 long non-coding RNAs (lncRNAs) in the rice planthopper, Sogatella furcifera. These lncRNAs show restricted expression during development, offering insights into insect biology and pest control.
Area of Science:
- Genomics
- Molecular Biology
- Entomology
Background:
- Long non-coding RNAs (lncRNAs) are crucial for fundamental biological processes in insects.
- Understanding insect lncRNA function is vital for agricultural applications, including pest management and resource utilization.
Purpose of the Study:
- To perform a genome-wide characterization of lncRNAs in the insect Sogatella furcifera.
- To investigate the expression patterns and regulatory relationships of lncRNAs during insect development.
Main Methods:
- Utilized a custom bioinformatics pipeline for lncRNA identification in the Sogatella furcifera genome.
- Profiled lncRNA expression across different developmental stages.
- Analyzed the correlation between lncRNA expression and their neighboring protein-coding genes.
Main Results:
- Identified 1861 lncRNAs from 1852 loci in the Sogatella furcifera genome.
- Observed temporally restricted expression of lncRNAs, more so than protein-coding genes.
- Found increased lncRNA expression in embryonic and nymphal stages (4th and 5th instars).
- Discovered a correlation between lncRNA expression and their downstream coding neighbors on the opposite strand.
Conclusions:
- This study provides a comprehensive genome-wide catalog of lncRNAs in Sogatella furcifera.
- lncRNAs play significant roles in insect development, with distinct temporal expression patterns.
- The findings offer valuable candidates for future functional studies and insights into lncRNA regulation in insects.

02:39lncRNA - 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...

7.6K
PIWI-interacting RNAs, or piRNAs, are the most abundant short non-coding RNAs. More than 20,000 genes have been found in humans that code for piRNAs while only 2000 genes have been found for miRNAs. piRNAs can act at the transcriptional and post-transcriptional levels and have a vital role in silencing transposable elements present in germ cells. They are also involved in epigenetic silencing and activation. Previously, they were thought to function only in germ cells but new evidence suggests...

15.4K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...

18.4K
Small interfering RNAs, or siRNAs, are short regulatory RNA molecules that can silence genes post-transcriptionally, as well as the transcriptional level in some cases. siRNAs are important for protecting cells against viral infections and silencing transposable genetic elements.
In the cytoplasm, siRNA is processed from a double-stranded RNA, which comes from either endogenous DNA transcription or exogenous sources like a virus. This double-stranded RNA is then cleaved by the...

Overview
Gene expression is the process in which DNA directs the synthesis of functional products, that is, proteins. Cells can regulate gene expression at various stages. It allows organisms to generate different cell types and enables cells to adapt to internal and external factors.
Genetic Information Flows from DNA to RNA to Protein
A gene is a stretch of DNA that serves as the blueprint for functional RNAs and proteins. Since DNA is made up of nucleotides and proteins consist of amino...
