Cocoa bean grow a variety of fruit-bearing shade trees to supplement their income to help cope with the volatile cocoa prices. Although cocoa has been adapted to grow under a dense rainforest canopy, agroforestry does not significantly further enhance cocoa productivity. Cocoa bean The cocoa bean or simply cocoa (), which is also called the cacao bean or cacao (), is the dried and fully fermented seed of "Theobroma cacao", from which cocoa solids (a mixture of nonfat substances) and cocoa butter (the fat) can be extracted. Cocoa beans are the basis of the sweet food preparation called chocolate, and of such
Theobroma cacao of the cacao genome, of the Criollo cacao (of a landrace from Belize, B97-61/B2). In their publication, they reported a detailed analysis of the genomic and genetic data. The sequence of the cacao genome identified 28,798 protein-coding genes, compared to the roughly 23,000 protein-coding genes of the human genome. About 20% of the cacao genome consists of transposable elements, a low proportion compared to other plant species. Many genes were identified as coding for flavonoids, aromatic terpenes, theobromine and many other metabolites involved in cocoa flavor and quality traits, among which a relatively high proportion code for polyphenols, which constitute
