A team of academic, government and industry researchers has completed a first draft of the cassava (Manihot esculenta) genome. The project is an important first step in accelerating the pace of research on this subsistence crop and addressing some of the many limitations that face cassava farmers around the world.
Cassava is a root crop that serves as the primary food source for more than 750 million people each day. Although it has many properties that make it an important food across much of Africa and Asia, it also has many limitations.
