DOE JGI Brachypodium distachyon genome sequence usage policy

Data Release Policy Message to scientists interested in accessing the completed Brachypodium distachyon genome sequence.

Sequencing of Brachypodium distachyon inbred line Bd21 has been completed by the Department of Energy Joint Genome Institute as part of its 'Community Sequencing Program'. This small grass species, is a model system for structural and functional genomics research on temperate grasses, including small grain crops such as wheat and barley, emerging bioenergy crops, and forage and turf grasses. The whole genome shotgun sequence assembly has been integrated with BAC-based physical maps and genetic linkage maps to produce a high quality final sequence assembly of with 99.6 % of the sequence contained in five scaffolds, each representing one of the chromosomes of Brachypodium.

As a public service, the completed Brachypodium genome sequence is being made available by the Department of Energy's Joint Genome Institute (JGI) before scientific publication according to the Ft Lauderdale Accord. This balances the imperative of the DOE and the JGI that the data from its sequencing projects be made available as soon and as completely as possible with the desire of contributing scientists and the JGI to reserve a reasonable period of time to publish on the genome sequencing and analysis without concerns about preemption by other groups.

JGI policy is that early release should aid the progress of science. By accessing these data, you agree not to publish any articles containing analyses of genes or genomic data on a whole genome or chromosome scale prior to publication by JGI and/or its collaborators of a comprehensive genome analysis ("Reserved analyses"). "Reserved analyses" include the identification of complete (whole genome) sets of genomic features such as genes, gene families, regulatory elements, repeat structures, GC content, or any other genome feature, and whole-genome- or chromosome- scale comparisons with other species.

The projected time line for publishing results of the Brachypodium genome sequencing project is mid-2009. Thus, the embargo on publication of such Reserved Analyses by researchers outside of the Brachypodium Genome Sequencing Project is expected to extend until this publication is accepted. Scientific users are free to publish papers dealing with specific genes or small sets of genes using the sequence data. If these data are used for publication, the following acknowledgment should be included: "These sequence data were produced by the US Department of Energy Joint Genome Institute http://www.jgi.doe.gov/." We request that you notify us upon publication of .This letter has been circulated to Journal Editors so that they are aware of the conditions of access and publication detailed above.

These data may be freely downloaded and used by all who respect the restrictions in the previous paragraphs. The assembly and sequence data should not be redistributed or repackaged without permission from the JGI. Any redistribution of the data during the embargo period should carry this notice: "the Joint Genome Institute provides these data in good faith, but makes no warranty, expressed or implied, nor assumes any legal liability or responsibility for any purpose for which the data are used." Once the sequence is moved to unreserved status, the data will be freely available for any subsequent use.

We prefer that potential users of this sequence assembly contact the Brachypodium Genome Sequencing Project co-directors (John Vogel, Michael Bevan, David Garvin, Todd Mockler) with their plans to ensure that proposed usage of sequence data are not Reserved Analyses.
