The Gramene Newsletter is a community resource about cereals and cereal genomics. It is a forum for community members to share news and current events. Some ideas for contributions include:
Articles, news items, events, opportunities or inquiries should be submitted to the GrameneNews editor at firstname.lastname@example.org. Gramene reserves the right to select contributions which meet the educational mission of the publication. Photos are also encouraged. Please provide print quality photos (300dpi) images, credit and caption information.
Gramene, the only platform for plant research that enables both forward and reverse genetics, has been awarded funding resources through the NSF Plant Genome Research Resource award, Award #0703908 . This abstract is shown here: The Gramene database (http://www.gramene.org) is an online resource, jointly supported by NSF and the US Department of Agriculture's Agricultural Research Service. It integrates the genomic, genetic and phenotypic information in rice, maize and other cereals, thereby giving scientists and other end-users easy access to this integrated information. This project will provide for the enhancement of Gramene by incorporating biological pathway and genetic diversity information from maize, rice, wheat, sorghum, and other cereals into the resource. Comparative genomics tools will be developed, thereby allowing researchers to use knowledge gained in one plant species to identify and characterize functionally significant genes and other elements in the genomes of other species. Scientists can use the resource to make advances in our fundamental understanding of the plant processes of economic importance such as hybrid vigor, grain development, seed dormancy, drought tolerance, and resistance to diseases. In addition, the tools developed will allow for the estimation of the breeding value of individual genetic variants, thereby providing breeders with the ability to select the ideal combinations of seed stocks to create varieties that have desirable traits such as robustness, the ability to grow in marginal environments, or have high potential as a source for biofuels and other materials of high economic value.
Information resources developed, and being developed, through genomics efforts are key elements to advance our fundamental knowledge base for a future bio-based economy and to address the expected need for feeding an expanding world population. Many of the information resources are still underutilized because of the fragmentation of the datasets and the absence of tools to make meaningful connections among them. To fully unlock the potential of plant genome data, the diverse datasets must be integrated so that information is shared both within and between species. It is one of the goals of Gramene to provide that integration. Another goal of the project is to deliver the integrated dataset into the hands of plant geneticists, molecular biologists, evolutionary biologists and breeders by providing compelling, intuitive, user interfaces. Lastly, the project will reach out to students, the public, and to underrepresented minorities via a series of online tutorials and on-site workshops that involves a novel, and cost-effective, public/private partnership.
All the information resources generated by Gramene will be available to scientists, breeders, and members of the general public free of charge and without intellectual property restrictions.

Have you visited Gramene's web-accessible database recently? If not, you may be in for a few surprises!
The Gramene website layout was reformatted back in January, and now the majority of the Gramene datasets (modules) have a consistent interface to aid in the integration of all the data sets. Rather than having module sub-menus, the Genes, Markers, QTL, Proteins, Ontologies, Diversity and Publications present a new layout with collapsible and expandable sections (see Figure 1). When opening the information page for an item in any of these categories, the general information will be displayed and remain open at the top of the page. Below this general information will be sections for links to other datasets (with the number of links identified for each section) and will vary depending upon the module you are in. Each section can be expanded or collapsed by clicking on the section title. Categories with no correspondences will be greyed out. On these pages, the "Map Positions" offers a "CMap Preview" option. Click on this option to get a preview of the map in CMap, or click on "View Comparative Map" to go to the actual map.
The help documentation has also been put into this consistent interface with expandable/collapsible sections. You may view it at http://www.gramene.org/db/help (see Figure 2).
The genome web server was upgraded to Ensembl release 46 , and there is a new genome browser for Oryza sativa ssp. indica. New gene tracks include a Gramene evidence-based gene track (37,176 genes); a RAP (The Rice Annotation Project, http://rapdb.dna.affrc.go.jp) gene track (29,132 genes); and the Consensus gene track: (14,842 genes). The OMAP sets have been remapped, and, new Poaceae EST/mRNA/GSS DNA sequences were downloaded from NCBI GenBank to the Gramene Markers database, and mapped to theOryza sativa TIGR v5 assembly using BLAT. The succesfully mapped sequences can be viewed as DNA aligned features in the contigview.
New markers of note are 2,243 maize eSSRs from the Maize Genome Sequencing Project. Data in the Maps Module is built out of the mappings in the Markers Module. Updates in the latter module are encorporated here. Of note is the new sequence map for indica, and, as noted in the "Genomes" section above, the OMAP sets have all been updated.
Most of the rice genes with the first character of the gene symbol from "A" to "Z" in our database now have ontology associations to TO, GO and PO. Additionally, 3,385 new genes records were downloaded from GrainGenes.
One recent improvement is that all QTL have been described and annotated by multiple ontologies. In addition to the Trait Ontology (TO) and Plant Ontology (PO) terms used in previous releases, Environment Ontology (EO) terms have been added this build to describe environmental conditions under which a particular QTL has been identified. These terms have been annotated by creating a default mapping based on the expertly identified TO and EO associations.
Another recent important improvement in this release is the provision of QTL-associated molecular marker info. We currently provide two types of associated markers for a particular QTL: Co-localized markers are the markers co-localized or overlapping with a QTL region on the original QTL map; and neighboring markers are those not overlapped but closely adjacent to a QTL region. The associated marker info is crucial for QTL fine mapping, map-based positional cloning, and marker-assisted selection (MAS) for plant breeding. We are pleased to announce the addition of five new species to the Gramene pathway tools (RiceCyc) module. These are Capsicum anuum, Coffea canephora, Medicago truncatula, Solanum lycopersicum and Solanum tuberosum. RiceCyc now allows you to draw comparisons among the data sets from eight species. Six pathways were added, two pathways deleted, and five pathways modified during this round of curation.
