- Global economy interacts with climate change to jeopardize species conservation: the case of the greater flamingo in the Mediterranean and West Africa. Financial crisis leads to closing down of Mediterranean saltpans, which is not good news for flamingo. Climate change doesn’t help. Must be similar examples for plants, Shirley.

- Evolutionary History of Pearl Millet (Pennisetum glaucum [L.] R. Br.) and Selection on Flowering Genes since Its Domestication. Bayesian modelling of 20 random genes supports domestication about 4,800 years ago, with protracted introgression from the wild relative, and selection sweeps suggest flowering related genes unsurprisingly underwent strong selection as the crop spread southward. But a single domestication scenario? Anyway, sounds familiar, doesn’it.
- Genome-Wide Analysis of the World’s Sheep Breeds Reveals High Levels of Historic Mixture and Strong Recent Selection. Much like, ahem, pearl millet. For flowering genes, read horniness genes. The bit about an initially broad sampling of diversity sounds a bit like the horse. Who out there is going to synthesize all this domestication stuff? Not that I’m looking for a meta-narrative, mind.

- Comparative genetic structure within single-origin pairs of rice (Oryza sativa L.) landraces from in situ and ex situ conservation programs in Yunnan of China using microsatellite markers. 2-5 times more unique alleles in the in situ version of various landraces compared to the ex situ version, collected in 1980. But same number of common alleles.

A valuable round up on watchamacallits (NUS, orphan crops, development opportunity crops etc etc)
On the Agricultures website our friends Stefano Padulosi and Paul Bordoni have just published a very valuable round-up on what they call “underutilized species”. 1 Valuable especially because it returns to the topic after six more years of research in the field, casting a historical eye over what worked and pointing out that these species — whatever you call them — can offer poor people a diversity of options to improve their lives, provided projects accept that it is complex and needs to be thorough.
The end-result … was very positive … and further confirmed that it is indeed possible to turn underutilized species into an effective instrument of development and improvement of peoples’ livelihood. This work did also demonstrate that the successful promotion of underutilized species needs to be solidly anchored in cultural-sensitive objectives that are fundamental in the sustainability of this work.
There is a lot more useful information in the article and the references it cites for anyone planning to work on underutilized species. That alone makes it worthwhile. More than that, though, it shows the value of returning to a topic after a little while, sharing the lessons learned, and bringing together in one place the many fascinating new activities, operational and planned.
I hope the African orphan crops project will be able to do something similar in six years time?
Survey on African orphan crops
Danny posted the following recently on the “Biodiversity for Food and Nutrition” Yahoo Group. I couldn’t find it anywhere else online, so he may have got it by email, I’m not sure. He did ask for it to be more widely disseminated, so here goes. We have mentioned the African Orphan Crop Consortium here before, mainly, if memory serves, to question whether sequencing the genome of said crops was necessarily the best way to spend $40 million. But then we would, wouldn’t we.
“The African Orphan Crop (AOC) consortium had a successful launch at the Clinton Global Initiative in September and the Beijing Genomic Institute has already started work on sequencing winter-thorn acacia (Faidherbia albida). 2 After gathering wonderful feedback from our meeting this summer, we are now conducting a survey to guide the next steps of the project. Via the survey, you are invited to contribute your knowledge and opinions to inform the selection process for the first 20-25 crops that the consortium will genetically sequence. We deeply appreciate your willingness to share insights with this project and would encourage you to forward the survey to others in your network who might like to participate.
The results of this survey will be used by the consortium to inform a process for prioritizing which crops will be initially selected for genetic sequencing, assembly, and annotation by the consortium. As discussed this summer, once this information is developed, it will be placed into the public domain, and plant breeding programs will be established to support development of these crops including the training of 750 plant scientists in Africa. Ultimately, we would like to sequence all of the appropriate crops on this list, and we believe that the momentum generated by the first set of sequenced crops will attract additional interest and funding.
