Thought that would get your attention. Actually, what the research summarized here revealed was that a couple of genes mutated independently thousands of years ago in the ancestor of the modern grapevine, whose berries were red. The resulting white variety proved to be the ancestor of almost all of the 3000 or so white grape varieties we have today. This discovery from CSIRO will apparently be useful in marker-assisted breeding.
Audible Darwin
It is easy to forget sometimes that The Origin of Species actually starts with a lengthy discussion of genetic diversity in crops, ornamentals, livestock and pets, although of course Darwin doesn’t call it that. He calls it “variation under domestication,” and you can now hear his seminal words, by downloading 24 hours’ worth of audio files from here. There’s a also a link to an e-text of the book.
Rice diversity
Chow.com, basically a recipes site, has a really nice feature on rice, the different types, the different processing methods, and of course the different ways of cooking it.
Getting enough vitamin A in Kenya
There’s an interesting juxtaposition of material in today’s Nation. Unfortunately, none of it is online so you’ll just have to take my word for it, unless you live in Kenya that is. On the one hand there’s an advertising feature announcing the launch of fortified fats and oils. The four-page spread says that “a team representing government, the standards setting body, testing agencies and the private sector brought Vitamin A-fortified oil to the supermarket shelves in only 130 days.” It includes statements by the Ministers of Health and of Trade & Industry, the Director of Medical Services, the Director of the Bureau of Standards, the Director of the Kenya Medical Research Institute and the Africa Regional Director of the Micronutrient Initiative. The mid-term review of the effort is on the Micronutrient Initiative website here.
Interestingly, the Ministry of Agriculture seems not to have been involved, but in a different part of the paper there’s an article about the widespread and rapid adoption of new, vitamin A-rich sweet potato varieties by communities in western Kenya as part of a project funded by Farm-Africa under the Community Mobilisation Against Desertification (CMAD) programme, in which that ministry did take part. A women’s group in Homa Bay has set up a bakery that uses sweet potato flower mixed with wheat to make bread, cakes and other products for local schools and hospitals.
So, two contrasting ways of trying to achieve the same thing: and end to hidden hunger. I wonder which approach will end up proving better value for money? Do we need both?
Bee problems caused by monoculture?
The New York Times picked up the Bees in Peril story and amplified it considerably. More interesting still, over at Resilience Science Garry Peterson points out that maybe the decline in pollinators is linked to the fact that introduced European bees have displaced natural populations to such an extent, and that the bees are now more genetically uniform. Sounds like he could be right.
