PeanutBase: A Resource for Peanut Researchers and Breeders

The PeanutBase website (http://peanutbase.org) includes genome browsers, genetic map viewers, sequence search tools, and a database of traits and QTLs. We have created marker-assisted selection pages with detailed information about markers and accessions for some high-value peanut traits. The website and database hold the genome sequences of the two closest ancestors of cultivated peanut (Arachis duranensis and Arachis ipaensis – progenitors of the cultivated tetraploid, Arachis hypogaea). 

New features in 2015 include a gene expression atlas for cultivated peanut, new tools for exploring genes and gene families; improved marker metadata, diploid and tetraploid genetic maps; additional QTLs (root-knot nematode resistance, bruchid resistance, kernel quality, and other traits). We have added more than a thousand images of germplasm accessions (pods, seeds, and plants), with links to the USDA GRIN germplasm database.

This resource is being developed for peanut researchers and breeders worldwide, with support from The Peanut Foundation/Peanut Genomics Initiative and the many contributors that have made the Peanut Genomics Initiative possible. Additional support has come from USDA-ARS. This database is developed and hosted by Iowa State University and the USDA-ARS SoyBase and Legume Clade Database group in Ames, Iowa, with contributions from the National Center for Genomic Resources (NCGR) and other participants.
