Distribution and Climatic Adaptation of Wild Tomato ( L.) Populations in Mexico.

Tomato ( L.) is a vegetable with worldwide importance. Its wild or close related species are reservoirs of genes with potential use for the generation of varieties tolerant or resistant to specific biotic and abiotic factors.

Climatic Diversity and Ecological Descriptors of Wild Tomato Species ( sect) and Close Related Species ( sect y sect. ) in Latin America.

Conservation and sustainable use of species diversity require a description of the environment where they develop. The objectives were to determine ecological descriptors and climatic diversity of areas along the distribution range of 12 species of wild tomatoes ( sect. ) and four wild species of phylogenetically related groups ( sect.

Ecogeography of teosinte.

Adaptation of crops to climate change has motivated an increasing interest in the potential value of novel traits from wild species; maize wild relatives, the teosintes, harbor traits that may be useful to maize breeding. To study the ecogeographic distribution of teosinte we constructed a robust database of 2363 teosinte occurrences from published sources for the period 1842-2016. A geographical information system integrating 216 environmental variables was created for Mexico and Central America and was used to characterize the environment of each teosinte occurrence site.
