Abstract
Landraces are important resources for breeding programs. However, the diversity harbored at the genomic level by landraces is yet to be analyzed. Here we sequenced more than 200 individual plants from the long-lasting and durably resistant rice landrace Acuce (Oryza sativa subsp. indica). We found that Acuce exhibits diversity levels as high as 38% of the entire indica sub-species. We pinpoint signatures of selection in favor of polymorphism associated with resistance, but not other agronomic trait genes. Furthermore, we provide evidences that emerging properties upon mixing genomic diversity also increase Acuce's performances.
