Resumen:
Plant domestication occurred independently in four different regions of the Americas. In general, different species were domesticated in each area, though a few species were domesticated independently in more than one area. The changes resulting from human selection conform to the familiar domestication syndrome (see Hammer 1984), though different traits making up this syndrome, for example loss of dispersal, are achieved by different routes in crops belonging to diffserent families. As one of the primary centres of origin, there is rich diversity of crops in the Mexico, Central and South American regions, with more than 124,993 species of vascular plants, belonging to 355 families and 6,227 genera (Ulloa et al. 2017). Among them there are several hundreds of cultivated plants. Remarkably it harbors dozens of crops having their origins in the Americas, and also many crops with a secondary centre of diversity cultivated here with high intensity and often for a long history. In recent decades, the number of cultivated plants (especially ornamentals) has dramatically increased because of rapid economic development of the worldwide economies. The Mexican, Central and South American traditional medicinal culture is a major factor driving the introduction, domestication and cultivation of medicinal plants on a large scale. For the Central American and Caribbean region of diversity 2,130 cultivated species have been reported, representing 810 genera from 165 plant and fungus families. The domestication assessment for C America counts 99 species for the highest category (5), while for 26 species a secondary centre of diversity is indicated (4). © 2025 Taylor & Francis Group, LLC.
