Theobroma cacao as culinary, purposes. Some mixtures included maize, chili, vanilla ("Vanilla planifolia"), and honey. Archaeological evidence for use of cacao, while relatively sparse, has come from the recovery of whole cacao beans at Uaxactun, Guatemala and from the preservation of wood fragments of the cacao tree at Belize sites including Cuello and Pulltrouser Swamp. In addition, analysis of residues from ceramic vessels has found traces of theobromine and caffeine in early formative vessels from Puerto Escondido, Honduras (1100–900 BC) and in middle formative vessels from Colha, Belize (600–400 BC) using similar techniques to those used to extract chocolate residues from four
Cacao yellow mosaic virus Cacao yellow mosaic virus Cacao yellow mosaic virus (CYMV) is a virus in the family Tymoviridae that infects cacao trees in Sierra Leone. CYMV, like other "Tymoviridae" are non-enveloped viruses, surrounded by a capsid approximately 30 nanometers wide. The viral capsid has T = 3 symmetry. "Tymoviridae" have positive-sense single-stranded RNA genomes approximately 6 kilobases long. In the cacao tree, CYMV infection leads to the appearance of large circular yellow blotches on the leaves. Infected trees are not killed or severely inhibited. CYMV has only been found in Sierra Leone where it primarily infects the cacao tree "Theobroma cacao". However,
