Summary
Next-generation sequencing enables the discovery of small interfering RNAs (siRNAs) and microRNAs (miRNAs) in plants. This protocol details constructing small RNA cDNA libraries for advanced sequencing technologies, improving the identification of low-abundance regulatory RNAs.
Area of Science:
- Plant molecular biology
- Genomics
- RNA biology
Background:
- Small interfering RNAs (siRNAs) and microRNAs (miRNAs) are crucial non-coding RNAs regulating plant development and genome stability.
- Traditional cloning and sequencing methods are insufficient for discovering low-abundance miRNAs.
- Next-generation sequencing (NGS) offers a powerful approach for small RNA discovery.
Purpose of the Study:
- To describe a protocol for constructing small RNA cDNA libraries.
- To enable the identification of novel miRNAs and other small RNAs using NGS technologies.
Main Methods:
- Construction of small RNA cDNA libraries.
- Adaptation of libraries for sequencing-by-synthesis (SBS) platforms (e.g., Roche Genome Sequencer FLX, Illumina Genome Analyzer).
Main Results:
- The described protocol facilitates the preparation of small RNA samples for high-throughput sequencing.
- This method is effective for discovering previously unidentified miRNAs and siRNAs, especially those expressed at low levels.
Conclusions:
- The protocol provides a robust method for small RNA library construction for NGS.
- This approach enhances the discovery of regulatory small RNAs in plants, advancing research in plant development and genetics.

03:21RNA-seq
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.
Before the discovery of RNA-seq, microarray-based methods and Sanger sequencing were used for transcriptome analysis. However, while microarray-based...

02:35RACE - Rapid Amplification of cDNA Ends
Rapid Amplification of cDNA Ends, or RACE, is one of the most effective methods to obtain a full-length cDNA from an mRNA sequence between a known internal region to the unknown sequence at the 5’ or 3’ end. The unknown region is cloned in the cDNA by a gene-specific primer that binds the known end, and a hybrid primer that attaches a predefined anchor sequence to the unknown end of the cDNA. The sequence in between is amplified by PCR with an anchor primer and a gene-specific primer.
