Cassava (Manihot esculenta), a major staple crop, is the main source of calories for 500 million people across the globe. No other continent depends on cassava to feed as many people as does Africa. Cassava is indispensable to food security in Africa. It is a widely preferred and consumed staple, as well as a hardy crop that can be stored in the ground as a fall-back source of food that can save lives in times of famine. Despite the importance of cassava for food security on the African continent, it has received relatively little research and development attention compared to other staples such as wheat, rice and maize. The key to unlocking the full potential of cassava lies largely in bringing cassava breeding into the 21st century. [More...]

Cassava genome v5.1 chromosome-scale genome assembly released!
The new version consists of the v4.1 scaffolds anchored onto the International Cassava Genetic Map Consortium framework and the pseudomolecule sequences can be downloaded from Phytozome. The Phytozome V10 gene models were mapped onto the v5.1 genome assembly.
