Interpretive Summary:

Technical Abstract: The competitiveness of peanuts in domestic and global markets has been threatened by losses in productivity and quality that are attributed to diseases, pests, environmental stresses and allergy or food safety issues. The U.S. Peanut Genome Initiative (PGI) was launched in 2004, and expanded to a global effort in 2006 to address these issues through coordination of international efforts in genome research beginning with molecular marker development and improvement of map resolution and coverage. Ultimately, the peanut whole genome sequencing project was launched in 2012 by the Peanut Genome Consortium (PGC), a coalition of international scientists and stakeholders that will guide and implement research conducted in the Peanut Genome Project (PGP) as an integral program of the International Peanut Genome Initiative (IPGI). IPGI has over 135 members, in 20 countries at 79 institutions and is a committed step by the world-wide peanut research community to meet the needs of the peanut industry through genomics and biotechnology. PGP goals are: 1) a high quality chromosome scale draft of a tetraploid (cultivated species) reference genome sequence, 2) high throughput genome and transcriptome characterization of tetraploid and diploid (progenitor species) genetic resources, 3) phenotypic trait association with genetic haplotypes, and 4) interactive bioinformatic resources for data curation and analysis. The outcome of these efforts will enable molecular breeding approaches for enhancing peanut yielding ability, resistance to diseases and insects, tolerance to environmental stresses, and improved quality traits. The large size of 2.8 Gb and allotetraploid nature of the peanut genome are challenges for peanut sequencing and assembly. Therefore an integrated approach has be deployed that complements whole genome sequencing (WGS) with BAC x BAC, GWAS with Recombinant Inbred Lines (RILs), and emerging sequencing technologies to bring the assembly together. SNP discovery also will contribute to a high-density genetic map for chromosome level assembly.
