Trans-acting small interfering RNA databases | Non-coding transcript data analysis
In plants, many trans-acting small interfering RNA (ta-siRNA) regulatory pathways have been identified as significant components of the gene networks involved in development, metabolism, responses to biotic and abiotic stresses and DNA methylation at the TAS locus.
It is the updated version of PMRD. PNRD mainly focuses on plant species. A total of 25739 entries of 11 different types of ncRNAs from 150 plant species were collected. Targets of miRNAs were extended to 178138 pairs in 46 species, while the number of miRNA expression profiles reached 35. Improvements in PNRD are not only the larger amounts of data, but also better service, such as a more user-friendly interface, more multifunctional and browsing options and more background data for users to download.
A freely accessible resource to serve as a repository for the sequences of ta-siRNA regulatory pathway-related microRNAs, TASs, ta-siRNAs and ta-siRNA targets, and for the cascading relations among them. tasiRNAdb also provides a tool named TasExpAnalysis that was developed to map user-submitted small RNA and degradome libraries to a stored/input TAS and to perform sRNA phasing analysis and TAS cleavage analysis.
