Chocolate Genes

A science news story that has been circulating in the media this week is the sequencing of the chocolate genome. I know I’ve already talked about genome sequences and why I think some are more important and interesting than others so I won’t bore you with that. But, I did want to put up links to a couple of different articles on the subject because I think it is interesting to compare and contrast the headlines and leads in terms of who went for the cheesy chocolate jokes, who worked the chocolate in a subtle way, and who went for a strictly hard news angle.

I think if I had to choose I’d go for middle of the road approach (which is usually a pretty safe place to be) and say that you have to work the chocolate in, in some way because its what makes the story fun, but that you don’t have to get ridiculous with yourself and lose the science and the purpose of the story.

CNN: Sweet scientific discovery in the world of chocolate
ScienceDaily: Sequencing of cacao genome to help chocolate industry, subsistence farmers
GenomeWeb: Consortium Using 454, Illumina Sequencers to Decode Cacao Genome
US News and World Report: A Taste of the Chocolate Genome
SiFy News: Cacao genome sequencing a boon to chocolate lovers
CBS News: Sweet Science Cacao Genome Map Completed
Scientific American: Candy-maker releases cacao (coco) genome sequence online
Reuters: Scientists Unlock Coca Genome, Release to Public Domain
New York Times: Rival Candy Projects Both Parse Cocoa’s DNA
AOL News: Wunderbar! Scientists Crack Chocolate’s DNA Code

Overall, I think that all these articles (which are just a sampling of what is out there) have interesting differences in the way they handle the headlines and even the rest of the body of the story. It might all be about chocolate, but each news organization definitely puts on their own spin.

Wheat Genome Adds to Available Draft Sequences

Scientists have released the draft sequence of the wheat genome. There are new draft sequences being released all the time as genome sequencing capabilities have increased. While they are all important because they increase researchers’ overall knowledge of the organisms that have been sequenced and how all organisms interact and are interrelated, some sequences have a far greater impact than others.

I’ve written about a few genome sequences that were released in the last year for BioTechniques, but I thought the wheat genome was worth mentioning because of the obvious impact it will have on the food industry. Whenever a staple crop is sequenced it adds to researchers abilities to tackle issues like world hunger by making super foods, but that is an issue which is controversial in and of itself. The more we learn, the more we can do. But just because we can make genetically modified foods that thrive in unconventional climates, should we?

Also just a note about why it is called a draft sequence and not just the sequence: every genome that is sequenced starts as a draft, when researchers sequence a genome there are parts of it that they either don’t understand the function of, or that they haven’t been able to unravel. So, the working genome that researchers use is a draft, it is what researchers will use compare their own sequencing work with that organism, to check for accuracy. But it is just a draft, drafts can be amended later if need be. Essentially, it goes back to the main nature of scientific exploration: researchers are constantly building on their knowledge base, which is why most scientific findings are left open to be improved upon as researchers learn even more.

Draft sequences I’ve reported on in the last year:
Horse Genome
Corn Genome
Hydra Genome
HIV Genome
King Tut’s Genome
