Arturo Gómez-Pompa Professor of Ecology and Botany in the Faculty of Sciences of the National University in the Institute of Biology at UNAM. These distinctive and academic positions have gained Gómez-Pompa a prestigious reputation in the ecological world. He discovered the use of Theobroma cacao, or the tree of chocolate, as ancient crops in rejolladas and cenotes within the Yucatán Peninsula. This confirmed his hypothesis on the anthropogenic origins of the Mayan forests and advanced future research in the domestication of tropical trees. Gómez-Pompa created a database for the Flora of Veracruz project in the 1960s that is still utilized to this
Cacao swollen-shoot virus ambitious and costly eradication effort of any country in the world against a viral plant disease. Cacao swollen-shoot virus (CSSV) principally infects "Theobroma cacao" (cacao tree) and has a major effect on crop yields. Within one year of infection yields decrease by 25%, and within two years by 50%. The trees are usually killed within 3 to 4 years. Symptoms vary depending on the strain of virus. Main symptoms include: leaf chlorosis (interveinal), root necrosis, red vein banding in young leaves, small mottled pods, and stem/root swelling followed by die-back. CSSV has also been isolated from alternative hosts "Cola chlamydanta",
