Crops and their domestication are an ideal model to study the genomic signatures of adaptation as adaptive traits are known and different plant species show varying levels of domestication. We study the incomplete domestication of the South American pseudo-cereal, amaranth, and the domestication and cultivation history of maize. To understand how complex traits adapt to changing environments, we combine population and quantitative genetic methods with molecular experiments. With our work we aim to understand how wild plants became crops and how these crops spread across the globe.
