ASRP

Eukaryotes produce functionally diverse classes of small RNAs (20-25 nt). These include microRNAs (miRNAs), which act as regulatory factors during growth and development, and short-interfering RNAs (siRNAs), which function in several epigenetic and post-transcriptional silencing systems. The Arabidopsis Small RNA Project (ASRP) seeks to characterize and functionally analyze the major classes of endogenous small RNAs in plants. The ASRP database provides a repository for sequences of small RNAs cloned from various Arabidopsis genotypes and tissues. Version 3.0 of the database contains 1920 unique sequences, with tools to assist in miRNA and siRNA identification and analysis. The comprehensive database is publicly available through a web interface at http://asrp.cgrb.oregonstate.edu.[1]

Development of the Arabidopsis Small RNA Project (ASRP) Database, which provides information and tools for the analysis of microRNA, endogenous siRNA and other small RNA-related features, has been driven by the introduction of high-throughput sequencing technology. To accommodate the demands of increased data, numerous improvements and updates have been made to ASRP, including new ways to access data, more efficient algorithms for handling data, and increased integration with community-wide resources. New search and visualization tools have also been developed to improve access to small RNA classes and their targets. ASRP is publicly available through a web interface at http://asrp.cgrb.oregonstate.edu/db/.[2]
