Summary
High GC content and low GC content fluctuation (GCF) at small RNA (sRNA) sites may boost sRNA expression. This finding offers insights for enhancing RNA interference (RNAi) and gene silencing efficiency.
Area of Science:
- Molecular Biology
- Genomics
- Plant Science
Background:
- Small RNAs (sRNAs) play crucial roles in gene regulation.
- Understanding the genomic features influencing sRNA expression is vital for genetic research.
Purpose of the Study:
- To investigate the relationship between GC content, GC content fluctuation (GCF), and sRNA generation in plants.
- To explore the potential of these genomic features for improving gene silencing technologies.
Main Methods:
- In silico systematic analysis of GC content and GCF in sRNA-generating sites and flanking regions.
- Correlation analysis of GC content with MITE-derived sRNA abundance and tasiRNA cluster GCF with phasing scores.
Main Results:
- High GCF observed at the borders of sRNA sites, with low GCF within sites.
- GC content in MITE families correlates with MITE-derived sRNA abundance.
- Negative correlation between GCF within tasiRNA clusters and their phasing scores.
Conclusions:
- High GC content and low GCF are associated with increased sRNA expression.
- Findings may inform strategies to enhance RNA interference (RNAi) and virus-induced gene silencing (VIGS) efficiency.

During most eukaryotic translation processes, the small 40S ribosome subunit scans an mRNA from its 5' end until it encounters the first start AUG codon. The large 60S ribosomal subunit then joins the smaller one to initiate protein synthesis. The location of the translation initiation is largely determined by the nucleotides near the start codon as there may be multiple translation initiation sites present on the mRNA. Marilyn Kozak discovered that the sequence RCCAUGG (where R...

5.7K
Because the DNA segments are cut and reorganized in a direction-specific manner, site-specific recombination has emerged as an efficient genetic engineering technique. Flippase and Cyclization recombinases or Flp and Cre, respectively, are two members of the tyrosine recombinase family derived from bacteriophages, that are used to mediate site-specific DNA insertions, deletions, and targeted expression of proteins in mammalian cell lines.

RNA sequencing, or RNA-Seq, is a high-throughput sequencing technology used to study the transcriptome of a cell. Transcriptomics helps to interpret the functional elements of a genome and identify the molecular constituents of an organism. Additionally, it also helps in understanding the development of an organism and the occurrence of diseases.

Reporter genes are a type of protein-coding gene that are often tagged to a gene of interest. Once inside a target cell, reporter genes usually produce visually identifiable characteristics like fluorescence and luminescence when expressed along with the gene of interest. Thus, reporter genes “report” the presence or absence of genes of interest in an organism, determine the gene expression pattern, or track the physical location of a DNA segment or protein in the cell.

Bacteria and archaea are susceptible to viral infections just like eukaryotes; therefore, they have developed a unique adaptive immune system to protect themselves. Clustered regularly interspaced short palindromic repeats and CRISPR-associated proteins (CRISPR-Cas) are present in more than 45% of known bacteria and 90% of known archaea.
