Brachypodium Resources

Brachypodium distachyon is a small annual grass that researchers use as a model for the grasses used to produce biomass, food, feed and forage. Unlike the grasses grown as crops, B. distachyon is well suited to experimental manipulation in the laboratory because of its small size, compact genome, diploid nature, self compatibility, rapid generation time and simple growth requirements. In addition, numerous resources and methods (e.g. complete genome sequence, high efficiency transformation, large collections of natural accessions, many sequenced accessions and several RIL populations) are available that allow researchers to apply a suite of modern research methods to understand the unique aspects of grass biology. See here for a review of B. distachyon as a model system.

In addition to B. distachyon, other species in the genus are being used to study polyploidy (B. hybridum and B. stacei) and perenniality (B. sylvaticum).

Announcements (updated 12-21-2017)

Let us know if you have an announcement

  • The reference genome for the allotetraploid B. hybridum has been released on Phytozome as an early release genome.
  • The pan-genome of B. distachyon has been published in Nature Communications and is available online.
  • BrachyPan, a pan-genome website is now available to download and interrogate 54  de novo assemblies that were used to create a B. distachyon pan-genome.
  • Over 800,000 SNP mutations are now searchable on Phytozome. Look in jbrowse on the newly released Bd21-3 reference genome.
  • The 4th International Brachypodium Conference that will be held in Huesca, Spain from June 25-28, 2019. A preliminary program is available on the meeting website. Contact the organizer Pilar Catalan with any questions.
  • A second reference genome for B. distachyon is now available. The genome of line Bd21-3 was sequenced because it is the parent of the sequenced mutant populations. Note that Bd21-3 is a different inbred line than Bd21, the source of the first B. distachyon reference genome.
  • Reference genomes for Brachypodium stacei and B. sylvaticum are now available on Phytozome under early access terms.
  • The 3rd International Brachypodium Conference held in July 2017 in Beijing was big success thanks to Zhiyong Liu and the local organizing committee. The program is available at the meeting website. The abstract book can be downloaded here.
  • T-DNA insertion sites have been updated to the v3 genome assembly and are available through the T-DNA page or through jbrowse in Phytozome.
  • The first book on Brachypodium genomics has been published.
  • The election for the International Brachypodium Steering Committee (IBSC) has been completed. Click here to view the results.
  • An improved reference genome assembly (v3.0) and annotation are now available on Phytozome.
  • The abstract book from the third International Brachypodium conference held 16-19 June 2015, in Amherst Massachusetts can be downloaded from the meeting website.

Resources and methods

T-DNA mutants

A collection of 23,649 T-DNA mutants is available.

Chemical and radiation mutants

A CSP project “Creating a genome-wide sequence-indexed collection of grass mutants” to sequence populations of EMS, fast neutron and sodium azide B. distachyon mutants was initiated in 2015. This project is a collaboration with researchers in France (Richard Sibout, INRA, IJPB) and the United States (Debbie Laudencia-Chingcuanco, USDA-ARS, WRRC). To date, over 800,000 mutations from 859 lines have been identified and are available as a jbrowse track on the Bd21-3 reference genome on Phytozome. When completed, this will be an unprecedented resource for forward and reverse genetics. If you would like to be involved in the screening or characterizing of this collection, please contact us.

Reference genomes

An extremely high quality reference genome for B. distachyon Bd21 is available on Phytozome 12. Details of this highly improved assembly are available on Phytozome.

Additional reference genomes are available for B. distachyon Bd21-3 (parent of mutant populations), B. stacei , the allotetraploid B. hybridum and the perennial B. sylvaticum are also available on Phytozome.

Germplasm

A large collection of inbred lines from geographically diverse locations has been established. A large collection of lines from Turkey are described in “Development of SSR markers and analysis of diversity in Turkish populations of Brachypodium distachyon” and “Molecular, Morphological, and Cytological analysis of diverse B. distachyon inbred lines“. Most of the Turkish lines can be ordered from the National Plant Germplasm System. Many lines have been also been collected from Spain.

Garvin lab stocks including RIL populations.

Pan-genome and resequenced lines

A B. distachyon pan-genome created from 54 de novo assemblies has been published and is available from the BrachyPan website. An additional 65 lines have been sequenced and assembled and will be available shortly. Download this spreadsheet for a complete list of sequenced lines and their status.
