Theobroma cacao Theobroma cacao Theobroma cacao, also called the cacao tree and the cocoa tree, is a small ( tall) evergreen tree in the family Malvaceae, native to the deep tropical regions of the Americas. Its seeds, cocoa beans, are used to make cocoa mass, cocoa powder, confectionery, ganache and chocolate. Leaves are alternate, entire, unlobed, long and broad. The flowers are produced in clusters directly on the trunk and older branches; this is known as cauliflory. The flowers are small, diameter, with pink calyx. The floral formula is ✶ K5 C5 A(5°+5²) (5). While many of the world's flowers are pollinated
Theobroma cacao seed germination of "T. cacao," inhibiting growth of various types of microorganisms (such as different oomycetes, fungi, and bacteria), and preventing rotting by "Phytophthora megakarya". Various plant pests and diseases can cause serious problems for cacao production. The genome of "T. cacao" is diploid, its size is 430 Mbp, and it comprises 10 chromosome pairs (2n=2x=20). In September 2010, a team of scientists announced a draft sequence of the cacao genome (Matina1-6 genotype). In a second, unrelated project, the International Cocoa Genome Sequencing Consortium-ICGS, co-ordinated by CIRAD, first published in December 2010 (online, paper publication in January 2011), the sequence
