Since 1998, cassava has outperformed all the world’s major crops in relative production increase. It is also recognized as being resilient to climate change. Its global average yield, however, is only 13 Mt/ha, compared to a potential of at least 65 Mt/ha, partly due to the impact of pests and di...

Three lines of evidence (botanical, archaeological, and biochemical results) of multiple and independent domestication of wild populations of common beans in the Americas are revicwed. These domestication events took place at least 10,000 yr ago from different wild bean populations. In addition t...
