PeanutBase.org: A Genomic and Genetic Data Resource to Support Crop Improvement in Peanut

PeanutBase (http://peanutbase.org) is the primary web portal for information collected by projects within the Peanut Genomics Initiative to serve the peanut research community. The genomes of the closest diploid progenitors of peanut, Arachis duranensis and Arachis ipaensis, can be explored with both GBrowse and JBrowse. These genome browsers can be used to search and view gene models, markers, transcripts, RNAseq expression data, and to explore synteny with common bean and soybean. PeanutBase has multiple gene expression atlases from peanut (Arachis hypogaea), including RNAseq differential expression analysis from 22 peanut tissues, which are linked to GBrowse, gene sequences and gene annotations. PeanutBase has multiple search tools available, including a marker search tool which allows the researcher to search and view over 25,000 markers, from a variety of maps. A number of new search tools have been added at PeanutBase over the past year. The biggest addition is PeanutMine, an instance of the InterMine biological data warehouse (http://intermine.org). PeanutMine, housed at LegumeInfo.org (http://mines.legumeinfo.org), has powerful methods for combining and searching diverse genetic and genomic data sets. A major goal of PeanutBase is to provide data and tools for Arachis research to help improve peanut varieties by integrating genetic, genomic and trait information. PeanutBase is a collaborative project of The Peanut Foundation, USDA-ARS, NCGR, and the many dedicated researchers and breeders working on peanut.
