Scientists Sequence Faba Bean Genome

The faba bean (Vicia faba) in Flora von Deutschland, Österreich und der Schweiz, 1885.
Mar 9, 2023 by Enrico de Lazaro

Researchers have produced a high-quality chromosome-level genome of the faba bean (Vicia faba), one of the earliest domesticated crops. The faba bean (Vicia faba) in Flora von Deutschland, Österreich und der Schweiz, 1885. Faba bean was domesticated in the near East more than 10,000 years ago and its broad adaptability, value as a restorative crop in rotations and high nutritional density have propelled it to the status of a global crop grown on...
