These processes can generate the diversity necessary for novel adaptations and continued diversification of taxa. Previous research has suggested that not all regions of a genome are equally permeable to introgression. We have conducted one of the first genome-wide assessments of patterns of reciprocal introgression in plant populations. We found evidence that suggests domesticated maize received adaptation to highland conditions from a wild relative, teosinte, during its spread to the high elevations of central Mexico. Gene flow appeared asymmetric, favoring teosinte introgression into maize, and was widespread across populations at putatively adaptive loci. In contrast, genomic regions near known domestication and cross-incompatibility loci appeared particularly resistant to introgression in both directions of gene flow. Crop-wild study systems should play an important role in future studies of introgression due to their well-developed genomic resources and histories of reciprocal gene flow during crop expansion.</p>
