The cocoa genome to be sequenced

The United States Department of Agriculture-Agricultural Research Service (USDA-ARS), Mars, Incorporated, and IBM intend to apply their scientific resources to sequence and analyse the entire cocoa genome. Sequencing the cocoa genome is a significant scientific step that may allow more directed breeding of cocoa plants and perhaps even enhance the quality of cocoa, the key ingredient in chocolate.

The research results may enable farmers to plant better quality cocoa and, more importantly, help create healthier, stronger cocoa crops with higher yields, pest and disease resistance, and increased water and nutrient use efficiency. These crops may help protect an important social, economic and environmental driver in Africa, where 70 percent of the world's cocoa is produced. Additionally, Mars will make its research results freely available through the Public Intellectual Property Resource for Agriculture (PIPRA), which supports agricultural innovation for both humanitarian and small-scale commercial purposes.

'Sequencing the genomes of agriculture crops is a critical step if we want to better understand and improve a crop,' said Judy St. John, USDA-ARS Deputy Administrator for Crop Production and Protection, based in Beltsville, Md.

Genome sequencing may help eliminate some of the guesswork of traditional breeding. If the sequencing is completed, it is hoped that scientists and farmers will be able to better identify the specific genetic traits that allow cocoa plants to produce higher yields and resist drought or pests. Then, cocoa breeders may be able to grow plants with these desirable traits to produce unique, new lines of cocoa plants using conventional breeding techniques.

'As the global leader in cocoa science, Mars saw the potential this research holds to help accelerate what farmers have been doing since the beginning of time with traditional breeding, ultimately improving cocoa trees, yielding higher quality cocoa and increasing income for farmers,' said Howard-Yana Shapiro, Ph.D., global director of plant science for Mars, Incorporated.

The group anticipates that it will take approximately five years to complete the entire sequencing, assembly, annotation and study of the cocoa genome. Scientists from USDA-ARS and Mars will conduct various aspects of the project at the USDA-ARS facility in Miami. Researchers at the IBM T. J. Watson Research Centre in Yorktown Heights, New York, expect to use their computational biology technology and expertise designed to develop a genetic map and assemble and study the cocoa genome.

'This collaboration is an opportunity for us to apply our computational biology and supercomputing expertise to help improve an economically important agricultural crop,' said Dr Mark Dean, IBM Fellow and vice president, Technical Strategy and Global Operations, IBM Research. 'IBM Research is interested in enhancing and supporting growth and development in Africa, where 70 percent of the world's cocoa is produced. We look forward to helping the agricultural community in Africa, and in other emerging markets.'

Cocoa has been the subject of little agricultural research compared to other major crops such as corn, wheat and rice. And while cocoa is not grown in the U.S., for every dollar of cocoa imported, between one and two dollars of domestic agricultural products are used in the manufacture of chocolate products.

'We are delighted to work with Mars to allow free access to the cocoa genome sequence information in real time, while ensuring that the gene sequences will not be patented,' noted Alan Bennett, Executive Director of the Public Intellectual Property Resource for Agriculture. 'Once its genome is sequenced, it has the potential to provide positive social, economic and environmental impact for the more than 6.5 million small family cocoa farmers around the world.'

Mars and USDA-ARS have worked together during the past 10 years on research projects related to improving traditional methods of cocoa breeding and reducing the threat of pest and disease to the crop around the world. Mars and IBM also worked together on projects in the past, but this is the first project in which all three experts are working to yield benefits for the crop, the farmer and the consumer for many years to come. Mars, Incorporated, the world's largest chocolate company, is financially backing and coordinating this project.
