Amaranth is an ancient pseudo-cereal from the Americas that has been domesticated for its grains in Central and South America. In recent years, Amaranth regained importance because of its gluten-free nature, high nutritional value and good stress resilience. While amaranth is often referred to as one crop, three amaranth species have actually been selected in different regions of the Americas. Two in Central America (A. cruentus and A. hypochondriacus) and one in South America (A. caudatus). The three grain amaranth species have been domesticated three times independently from A. hybridus, making it an ideal system to study repeated evolution.
AmaranthGDB provides resources and tools to facilitate interdisciplinary amaranth research.
We provide the first amaranth population genetics genome browser, PopAmaranth. PopAmaranth facilitates browsing through different population genetic summary statistics and selection signals along the amaranth genome. The integration of gene annotation and variant calls for the three grain amaranths and two wild relatives
