title: iRootHair: a comprehensive root hair genomics database.
abstract: The specialized root epidermis cells of higher plants produce long, tubular outgrowths called root hairs. Root hairs play an important role in nutrient and water uptake, and they serve as a valuable model in studies of plant cell morphogenesis. More than 1,300 articles that describe the biological processes of these unique cells have been published to date. As new fields of root hair research are emerging, the number of new papers published each year and the volumes of new relevant data are continuously increasing. Therefore, there is a general need to facilitate studies on root hair biology by collecting, presenting, and sharing the available information in a systematic, curated manner. Consequently, in this paper, we present a comprehensive database of root hair genomics, iRootHair, which is accessible as a Web-based service. The current version of the database includes information about 153 root hair-related genes that have been identified to date in dicots and monocots along with their putative orthologs in higher plants with sequenced genomes. In order to facilitate the use of the iRootHair database, it is subdivided into interrelated, searchable sections that describe genes, processes of root hair formation, root hair mutants, and available references. The database integrates bioinformatics tools with a focus on sequence identification and annotation. iRootHair is a unique resource for root hair research that integrates the large volume of data related to root hair genomics in a single, curated, and expandable database that is freely available at www.iroothair.org.
