The Arabidopsis Gene Regulatory Information Server (AGRIS) provides a comprehensive resource for gene regulatory studies in the model plant Arabidopsis thaliana. Three interlinked databases, AtTFDB, AtcisDB and AtRegNet, furnish comprehensive and updated information on transcription factors (TFs), predicted and experimentally verified cis-regulatory elements (CREs) and their interactions, respectively.
The plant miRNA database (PMRD) integrates available plant miRNA data deposited in public databases, gleaned from the recent literature, and data generated in-house. This database contains sequence information, secondary structure, target genes, expression profiles and a genome browser. Includes model plants and major crops such as Arabidopsis, rice, wheat, soybean, maize, sorghum, barley, etc. For Arabidopsis, rice, poplar, soybean, cotton, medicago and maize, the possible target genes for each miRNA with a predicted interaction site are included in the database. In some instances, miRNA expression profiles are included in the PMRD.
Plant Transcription Factor Database (PlantTFDB) is database that attempts to identify a comprehensive set of plant genes coding for transcription factors. A web interface to the database allows users to browse by species, search using a sequence identifier, or query using BLAST.
The Plant Transcription Factor Database (PlnTFDB) is an integrative database that provides putatively complete sets of transcription factors (TFs) and other transcriptional regulators (TRs) in plant species whose genomes have been completely sequenced and annotated. For each gene family, a basic description is provided that is complemented by literature references, and multiple sequence alignments of protein domains. TF or TR gene entries include information of expressed sequence tags, 3D protein structures of homologous proteins, domain architecture and cross-links to other computational resources online. Moreover, the different species in PlnTFDB are linked to each other by means of orthologous genes facilitating cross-species comparisons.
The PREP (Predictive RNA Editors for Plants) suite predicts sites of RNA editing based on the principle that editing in plant organelles increases the conservation of proteins across species. Predictors for mitochondrial genes, chloroplast genes, and alignments input by the user are included.
psRNATarget is a plant small RNA target analysis server which features reverse complementary matching between small RNA and target transcript, and target site accessibility evaluation. It is designed for high-throughput analysis of next generation data, and outputs a comprehensive list of small RNA-target pairs.
pssRNAMiner is a web server which identifies trans-acting siRNA clusters in plants, as well as their potential phase initiators. Users input a small RNA dataset and specify a transcript-genomic library for mapping.
