Arachis duranensis, a wild herb native to Argentina, Bolivia, and Paraguay, is thought to be one of the diploid ancestors of cultivated peanut. Its genome has just been sequenced as part of the Peanut Genomics Initiative, to help in the accurate assembly of the more important cultivated peanut, A. hypogaea.

Cultivated peanut derived all of its genetic material from two wild ancestors, A. duranensis and A. ipaensis whose genomes merged several thousand years ago, in a rare genetic event. The wild species, therefore, have half as much genetic material as cultivated peanut. These two “simpler” genomes have first been sequenced toward achieving its ultimate goal: the complete genomic sequence for cultivated peanut.

The cultivated peanut is an allotetraploid (2n=4x=40) that carries both the A and B genomes and A. duranensis (2n=2x=20) has likely contributed the A genome, the smaller set of chromosomes in the karyotype. These two ancestral diploids separated from each other about 3 million years ago. The genome merger, allopolyploidy event, ocurred relatively very recently, five to ten thousand years ago, followed by domestication in South America from where it appeared in most part of the world by 1600.

NOTE: chromosomal pseudomolecules for A. duranensis and A. ipaensis were numbered according to previously published linkage maps; they mostly do not have known correspondences to cytogenetic numbers. Known correspondences are: cytogenetic A9 = Aradu.A08 and cytogenetic B3 = Araip.B06

Project Name
Project DescriptionArachis duranensis is a wild annual plant native to Argentina, Bolivia, and Paraguay. It is thought to be one of the diploid ancestors of cultivated tetraploid peanut. Arachis duranensis accession V14167 was sequenced at Beijing Genomics Institute, with funding from The Peanut Foundation, as part of the International Peanut Genome Initiative. The sequencing stragety was whole-genome shotgun, from eight Illumina paired-end sequencing libraries, with insert sizes ranging from 170 bp to 40 kb. The primary contig and scaffold assemblies were constructed using SOAPdenovo (v2.04).
