Cacao Pods and Chocolate

Welcome to the Cacao Genome Project

Cacao production is important! Not only is it the basic ingredient in the world’s favorite confection, chocolate, but it provides a livelihood for over 6.5 million farmers in Africa, South America and Asia and ranks as one of the top ten agriculture commodities in the world. Historically, cocoa production has been plagued by serious losses due to pests and diseases. The release of the cacao genome sequence will provide researchers with access to the latest genomic tools, enabling more efficient research and accelerating the breeding process, thereby expediting the release of superior cacao cultivars. The sequenced genotype, Matina 1-6, is representative of the genetic background most commonly found in the cacao producing countries, enabling results to be applied immediately and broadly to current commercial cultivars.  Matina 1-6 is highly homozygous which greatly reduces the complexity of the sequence assembly process. While the sequence provided is a preliminary release, it already covers 92% of the genome, with approximately 35,000 genes. We will continue to refine the assembly and annotation, working toward a complete finished sequence. Updates will be made available via this website, to keep informed check back regularly. If you have any questions, feedback or problems, please contact us through the contact link on the navigation bar, we promise to respond in a timely manner. 


About Cacao Genome Database

Cacao We have been maintaining two versions of Genome database examples: one is in PDF format, the other one is Excel format, you can get the PDF format from here.

PDF example:The PDF example is read-only, and can be opened in any PDF reader like Adobe Reader, pdfelement.

Excel example: Microsoft Excel format is preferred by someone who seeks a way to extract data from the spreadsheet to any SQL-compatible database, unfortunately we don't provide the excel format for the examples, you may need to use pdf to excel software to convert the examples from PDF format into Excel format.
