Whole-genome assembly of huauzontle (Chenopodium berlandieri subsp. nuttaliae) and its relationship to Andean quinoa

Pitseed goosefoot (Chenopodium berlandieri) is a free-living North American member of the American Tetraploid Goosefoot Complex (ATGC). It is a potential genetic resource for improving quinoa (C. quinoa) and is a Mesoamerican vegetable and seed crop. Cultigens are C. berlandieri subsp. nuttaliae, commonly known as huauzontle, and are treated as independent domesticates, rather than as translocated Andean quinoa. To test the utility of C. berlandieri as a genetic resource for C. quinoa, we assembled the whole-genome sequence of PI 433231, a huauzontle from Puebla, Mexico.
