Resumen:
The cultivated peanut (Arachis hypogaea) is widely used as a source of protein and oil andis cultivated worldwide in tropics, subtropics and in warmer areas of temperateregions. It is an allotetraploid species (2n=4x=40) of recent origin with an AABBgenome constitution. Cytogenetic and molecular evidence suggests that A. duranensis (A-genome) and A. ipaensis (B-genome) are the wilddiploid species (2n=2x=20) most likely involved in the origin of the cultigen. Todate, only one accession of A. ipaensisK30076 was ever found and is therefore considered to be the donor of the Bgenome in peanut. In contrast, there are many different accessions of A. duranensis that are possible donorsof the A genome. In this context, in order to identify the A.duranensis accession most closely related to that involved in the peanutorigin, weperformed whole genome sequencing of 11 different accessions of A. duranensis using MiSeq technology (Illumina).The NGSEP software was used todiscover SNPs and Indelsbetween the A. duranensis accessionsand the pseudomolecules of the cultivar TIFrunner (Arachis hypogaea subsp. hypogaeavar. hypogaea). This study will allow theidentification of the accession that more likely participated as the A genome donorof peanut genome, and will provide a better understanding of the genetic originof this crop.
