Comparing multiple genotypes in Flapjack format using Gigwa
Genome alignments available to date are listed below and are accessible from our species page under each of the species resources as JBrowse links.
Expression data quality metrics are now available: We have made available the quality metrics, MultiQC report with interactive graphics, for the expression dataset (Clevenger 2016) remapped to Tifrunner.gnm2.ann2. Links for expression related data have been compiled at the Gene Expression Resources page.
Userguide updated with gene family search: We have added instructions for finding gene family starting from a gene-id, phylogram or the tree view along with other members from legumes in our userguides collection.
BaileyII integrated into GCV: The BaileyII gene models have now been integrated with our Genome Context Viewer (GCV) tool enabling comparison with other Arachis and legume genomes. This gives a comparative view of the immediate neighborhood of the queried gene in the micro-syntenic region with added phylogenetic(gene family) information. Clicke here for a link to an example view.
Pangenes in GCV: The Genome Context Viewer has been linked to Arachis pangenes. The custom GCV instance. Clicking on the pangene takes to a link to the pangene report page in ArachisMine where all members are listed. Please note that the pangene view includes the NCBI annotation and helps lookup from the Genbank id to the corresponding annotations in other versions.
New Technology Platform: We have now moved to a new technology platform.
Arachis pangene set: Pangene set for Arachis species, based on A. hypogaea, A. duranensis, and A. ipaensis. This pangene set includes five annotation sets from A. hypogaea and one each from A. duranensis and A. ipaensis. More details and data at Data Store Arachis.pan1.4LN9.
Bailey II genome: Arachis hypogaea accession Bailey II, genome assembly 1. More details for BaileyII.gnm1.1JTF.
Tifrunner genome2: Genome assembly 2 for Arachis hypogaea, cultivar Tifrunner(Tifrunner.gnm2.J5K5). This version has structural changes relative to assembly 1.
Traits to associated markers using ArachisMine
Now it is possible to select a trait from the dropdown and and generate a list of associated markers from QTL/GWAS studies. The markers can be further explored for details using the links in the page.
‘Try it at ArachisMine’ (Click the GENETICS tab for the preset query, ‘Trait –> GeneticMarkers’) OR
use the link directly to this ‘query page’.
Search genes & traits by keywords
The ‘ArachisMine Gene Keyword Search’ and ‘Trait Keyword Search’ utilities are available from the Tools pannel. The search result lists the relevant features and are linked to the corresponding detailed display at ArachisMine.
Example: gene search with keyword ‘photosystem II’.
Example: trait search with keyword ‘pod’.
JBrowse2, a new genome browser
JBrowse2: a new and genome browser with enhanced functionalities implented at PeanutBase.

Gigwa2.5:Genotype comparison
Now it is possible to visualize variants between multiple lines within Gigwa(v2.5). This is achieved by selecting multiple individuals for display and then download and export as flapjack file format. The ‘keep files in server’ should be selected before export. Finaly, a click at ‘View in Flapjack-Bytes’ draws the visualization showing similarity and differences between the genetic lines at each of the SNPs.
Peanut core catalog
These images were taken to document unique traits of each accession during a large-scale project to comprehensively catalog the peanut core and mini core collection. Now the images of the accessions in the core collection are available as a catalog. (Contribution from Noelle Anglin, USDA-ARS and others)
New and improved assembly of Arachis ipaensis
A completely new PacBio and Hi-C sequence and assembly of the genome of Arachis ipaensis is now available (with some usage restrictions) at the PeanutBase Data Store as a result of a collaboration between USDA, University of Georgia, and Hudson Alpha. Arachis ipaensis is the B subgenome donor of cultivated peanut (A. hypogaea) and its wild counterpart A. monticola. This remarkable accession, K 30076, is the only collection of this species ever made. Its location, far from that of other B genome Arachis species, is incompatible with natural dispersal, indicating past transport by humans. Its extraordinarily high DNA identity with peanut’s B subgenome and location, close to Villa Montes in Bolivia where the landraces of peanut that combine the most primitive, or wild-like, characteristics are grown indicate that it is descended from the very same population that gave rise to the tetraploid species.
Peanut comparative expression data with other legumes
The peanut expression atlas data (Clevenger, et al. 2016) after remapping the reads to gnm2.ann1 is now in the CoNekT tool where the expression patterns can be compared with their orthologs in other legumes at LIS. You can

These images were taken to document unique traits of each accession during a large-scale project to comprehensively catalog the peanut core and mini core collection. Now the images of the accessions in the mini core collection are available as a catalog. (Contributor: Noelle Anglin, USDA-ARS)
Arachis Phenotype server
Phenotype data server for PeanutBase is now operational at ArachisPheno. We now have the phenotype data for the peanut mini core collection: agronomic traits and seed biochemical traits. If you have phenotype data for peanut lines to share with the community, please contact us to house it at PeanutBase, or you may try a self submission too.

New genome assembly for A. cardenasii, a diploid relative of peanut.
The genome of Arachis cardenasii, a relative of cultivated peanut, has been sequenced and is available here (with some usage restrictions) at the PeanutBase Data Store. This diploid wild species has been used as an important source of disease resistance in cultivated tetraploid peanut. Genome sequencing was funded by the USDA (Dr. Brian Scheffler leading), under the scientific guidance of Drs. David and Soraya Bertioli and colleagues.

We welcome assistance from our user community having expertise on such traits to contribute information to these trait specific pages. Please contact us for this purpose if you would like to contribute or maintain a MAS page for a specific trait.

Updated web framework and graphical themes
We have moved from the Tripal 1 / Drupal 6 web framework to Tripal 2.0a / Drupal 7. This shouldn’t affect the content of the site, but will make it easier to add a number of important features - such as an integrated BLAST sequence search module - and to keep up with ongoing Tripal development. Please let us know if you like (or dislike) any aspects of the updated site. We will be adding a lot of features through the coming year, but are eager to hear about features that you would like to have.

All available QTLs now accessible via a Summary Table
We have compiled and uploaded QTL data sets from 4 publications and now they are available at the Summary Table of All QTLs. More details are available by clicking the QTL and wherever available we have also provided a cmap link to our collaborative site Legume Information System. You can also search the QTLs using this search page. Please explore this data and we encourage the community to give us feedback to make this resource more useful as we go along. As we keep compiling more QTL data sets, they will be available here through this summary page. All QTL related resources are accessible via our QTLs page.
QTL terms with ontology compiled and available for download
Ontologies will be an integral part at PeanutBase and we are trying to make them consistent with those for other legume species, with specialized terms for peanut where necessary, and with synonyms for existing terms in the literature and in use. This will help towards enabling searches that will integrate trait information for multiple legume species provided by LegumeInfo.org, and will allow integration with other plant genetic databases. As of November, 2013, peanut QTL terms have been collected from published resources and are being aligned/integrated with the trait ontology developed at SoyBase. We have made this evolving resource, QTL terms with ontology, available for download as an excel spreadsheet. We also welcome and encourage comments and suggestions from the community about this resource.
(October-November 2013) A New Look for PeanutBase
(September 2013) Transcriptome assembly projects compiled and a few more QTL reports
(July-August 2013) QTL and map resources downloadable from one place
A few QTL and map resources were compiled with the goal to make them available for download from a single location. These resources will be enhanced through the Tripal’s Chado database schema for convenient data sharing with other legume projects using the same schema.
