PmiRKB -- Plant MicroRNA Knowledge Base
What you can do:
Find information about plant microRNAs.
Highlights:
- PmiRKB is a database of plant microRNAs.
- It has four modules: SNP, Pri-miR, MiR-Tar, Self-reg.
- In the 'SNP' module, single nucleotide polymorphism (SNP) data of seven Arabidopsis (Arabidopsis thaliana) accessions and 21 rice (Oryza sativa) subspecies were collected to inspect the SNPs within pre-miRNAs (precursor microRNAs) and miRNA-target RNA duplexes.
- Depending on their locations, SNPs can affect the secondary structures of pre-miRNAs, or interactions between miRNAs and their targets.
- 'Pri-miR' can be used to investigate the tissue-specific, transcriptional contexts of pre- and pri-miRNAs (primary microRNAs), based on massively parallel signature sequencing data.
- 'MiR-Tar' was designed to validate thousands of miRNA-target pairs by using parallel analysis of RNA end (PARE) data.
- 'Self-reg', also used PARE data to investigate the metabolism of miRNA precursors, including precursor processing and miRNA- or miRNA*-mediated self-regulation effects on their host precursors.
