It is a diverting exercise to look for the intersection between the “Ten moments that changed history,” according to Andrew Marr’s new history of the world, and the Royal Society’s list of the “most significant invention[s] in the history of food and drink.” So I’ll leave it to you.
Brainfood: South American threat map, Bee domestication, Rice origins, Legume diversity, Lima bean domestication
- Analysis of threats to South American flora and its implications for conservation. Bottom line: Ecuadorian and Colombian Andes, southern Paraguay, the Guyana shield, southern Brazil, and Bolivia. But don’t let that divert your attention from the cool maps.
- Management increases genetic diversity of honey bees via admixture. No genetic bottleneck there. And the same in more words, but not as many as the original paper.
- Phylogeography of Asian wild rice, Oryza rufipogon: a genome-wide view. When in doubt, throw more markers at it. Two groups in O. rufipogon, only the Chinese/Indochinese one related to cultivated rice (indica). Japonica out on a limb. And the longer version.
- Legume Diversity Patterns in West Central Africa: Influence of Species Biology on Distribution Models. Temperature variables are most important.
- Multiple domestications of the Mesoamerican gene pool of lima bean (Phaseolus lunatus L.): evidence from chloroplast DNA sequences. Andean and Mesoamerican cultivated genepools confirmed, and two sub-genepools within the latter, one originating in western central Mexico and the other between Guatemala and Costa Rica. Will they mash up with the study in the first link? Some of the people involved are neighbours and friends.

Taro help is at hand
It was a couple of years ago that we started talking about the arrival of taro leaf blight in West Africa, and the possible role that resistant material from the Pacific might have in averting a catastrophe. Well:
On 21 August 2012, help came with the arrival of breeders’ lines from Samoa and PNG and varieties from countries in Asia.
We will be following their progress with much interest.
Agrobiodiversity surveys galore
Within days of each other, surveys have been announced on Who is working on agricultural biodiversity? and On-farm management of PGRFA. I don’t know if there’s a connection between the two. Is something brewing out there? I think we should be told.
