N1  - We would like to express our appreciation to
U.S. Peanut Industries and the leadership of the
Peanut Foundation and American Peanut Council,
particularly to Howard Valentine for his efforts to
make this PGI and PGC a reality. We also thank
Dr. Howard Shapiro of Mars Inc. for initiating
discussions with BGI and opening the way for
collaborations with Chinese researchers. We are
grateful for the financial support from USDAARS,
Peanut Foundation, Georgia Peanut Commission
and U.S. National Peanut Board, Mars
Inc., Chinese genome collaborators (Henan Academy
of Ag. Sci., Oil Crops Research Institute of
Chinese Academy of Ag. Sci., and Hi-Tech Center
of Shandong Academy of Ag. Sci.), National Fund

N2  - 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. Narrow genetic diversity and a deficiency of polymorphic DNA markers severely hindered construction of dense genetic maps and quantitative trait loci (QTL) mapping in order to deploy linked markers in marker-assisted peanut improvement. 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, a peanut genome sequencing project was launched in 2012 by the Peanut Genome Consortium (PGC). We reviewed the progress for accelerated development of peanut genomic resources in peanut, such as generation of expressed sequenced tags (ESTs) (252,832 ESTs as December 2012 in the public NCBI EST database), development of molecular markers (over 15,518 SSRs), and construction of peanut genetic linkage maps, in particular for cultivated peanut. Several consensus genetic maps have been constructed, and there are examples of recent international efforts to develop high density maps. An international reference consensus genetic map was developed recently with 897 marker loci based on 11 published mapping populations. Furthermore, a high-density integrated consensus map of cultivated peanut and wild diploid relatives also has been developed, which was enriched further with 3693 marker loci on a single map by adding information from five new genetic mapping populations to the published reference consensus map
