The sweet potato is one of the world’s most widely consumed crops, yet its evolutionary history is poorly understood. In this paper, we present a comprehensive phylogenetic study of all species closely related to the sweet potato and address several questions pertaining to the sweet potato that r...
The phylogeny of water buffaloes (Bubalus bubalis) is still a matter of discussion, especially if the two types of domestic water buffalo (swamp and river) derived from different domestication events or if they are products of human selection. To obtain more insight, we analyzed the entire mito...
Globally, 800 million people are malnourished. Heavily subsidised farmers in rich countries produce sufficient surplus food to feed the hungry, but not at a price the poor can afford. Even donating the rich world’s surplus to the poor would not solve the problem. Most poor people earn their livin...
Chloroplast DNA polymorphisms were studied by PCR sequencing and PCR-restriction fragment length polymorphism in 165 accessions of domesticated landraces of common bean from Latin America and the USA, 23 accessions of weedy beans, and 134 accessions of wild beans covering the entire geographic ra...

The results of 2 Phaseolus lunatus germplasm collections, carried out in the Depts. of Cajamarca and Amazonas (Peru), are discussed in terms of origin and domestication problems of this crop. (AS-CIAT)
Some historical aspects and 2 possible reasons for the domestication of Phaseolus vulgaris and P. lunatus are considered, namely, that (1) bean domestication occurred at least 8000 yr ago in the southern Peruvian Andes, as a food plant, or that (2) beans were domesticated for different reasons an...
