  • (New) Genotype Comparison Visualization Tool, GCViT: It is a tool for whole genome visualization of resequencing or SNP array data. GCViT allows a user to compare two or more accessions and visually identify regions of similarity and difference across the genome.
    It is capable of multiple chromosome visualisation for the comparison of multiple accessions from a single dataset. It extracts information from VCF file and does a parallel comparison between two or more lines within that VCF file plotting the location of these differences on the chromosome for visualization. One can, for example, plot the differences between progeny and its parents to identify which regions are inherited from which parents. (More information and a video tutorial about GCViT is at GitHub and SoyBase.)
    We need your feedback on the usage of this tool and will appreciate it if you could let us know about your experience via Contact us.

(May 2014)

  • Pseudomolecule assemblies as 80 column multifasta files are now available for download
    We have made available the genome assemblies in a single 80 column multi-FASTA file, one for each diploid genome. These files contain the 10 pseudomolecule sequences in a 80 column format with the scaffold sequences concatenated (after ordering and orienting) and separated by spacer sequences of 10,000 “n”s. This format is compatible with some programs like IGV which requires the sequence lines be of equal width. They are available via our Genomes (assembly) page and labeled in the corresponding dipoid pages as follows:
Aradu_v1.0.fa.gz 01-May-2014 14:26 251M Pseudomolecules, one file
Araip_v1.0.fa.gz 01-May-2014 14:36 338M Pseudomolecules, one file
  • BLAST and BLAT: Sequence search features are now available at PeanutBase
    Sequence search feature is now available at PeanutBase via BLAST and BLAT utilities. You can search your sequence against Arachis duranensis (assembly ver 1.0) or Arachis ipaensis (assembly ver 1.0) in the ARACHIS BLAST page (the general purpose NCBI BLAST sequence search utility appropriate for genomic sequences).
    OR,
    you can use the BLAT alignment tool via the GBrowse pages for Arachis duranensis and Arachis ipaenensis. The BLAT alignment is recommended for aligning cDNA sequences against the corresponding assembly sequence.

    The steps for BLAT alignment are (at the GBrowse page):
    1. Select “Find Blat Alignment” in the drop-down menu for Configure.
    2. Click “Configure”
    3. In the “Find Blat Alignment” section that opens, enter your (single) sequence in the “Input Sequence to Align” box
    4. Click “Find”

    If a single hit is found, a new track called “BLAT” will be created in the genome browser with your aligned sequence. If multiple hits are found, you’ll have to select one from a list of locations.

    If you have questions or need further assistance please contact us.

(April 2014)

  • Genome Browser is now accessible for the two Arachis diploid progenitors.
    Genome Browser tracks are now available for the two diploid progenitor species, Arachis duranensis and Arachis ipaensis.

  • 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.
