Brainfood: Beans, Potatoes, Lettuce, Agave, Gaming, Mangroves, Ancient millets, Ancient missions

Mesoamerican origin of the common bean (Phaseolus vulgaris L.) is revealed by sequence data. Revealed is kinda strong isn’t it? This from a bean expert of my acquaintance: “Yes, we knew that, as it seems to be the case of all species of the Phaseoli section. They could have done a bit better in including the 2 populations of Cordoba mountain, in order to see whether these belong to the first migration to the Andes, or the second one. Wild vulgaris from western Panama, or Venezuela, could have helped in this regard too. We have shown years ago that the complex genetic structure in Mexico and in Colombia is the result of these floristic migrations combined with gene flow events because beans cross among themselves.”
The Enigma of Solanum maglia in the Origin of the Chilean Cultivated Potato, Solanum tuberosum Chilotanum Group. These are long-day adapted and therefore crucial to the history of the potato in Europe. But the various sorts of evidence looked at to investigate their relationship to the rare Chilean wild relative S. maglia just do not agree. Bummer.
Wild and weedy Lactuca species, their distribution, ecogeography and ecobiology in USA and Canada. So Iowa is a wild lettuce hotspot. If you’re interested in the germplasm, it’ll be in the genebank of Palacký University in the Czech Republic.
Sustainability of the traditional management of Agave genetic resources in the elaboration of mezcal and tequila spirits in western Mexico. Tequila industrial agriculture should learn from the traditional kind.
Fate of the World: computer gaming for conservation. Worth a try. No, really.
The Economic Value of Mangroves: A Meta-Analysis. You might think there would be a value in the abstract; you would be wrong.
Early millet use in northern China. That would be Setaria italica and Panicum miliaceum, and new evidence from ancient starch grain on pottery and grinding stones found in archaeological sites has pushed back their cultivation in N China by 1000 and 2000 years respectively, to about 9500-7500 BC. The Archaeobotanist has more, as ever.
Digitization and online availability of original collecting mission data to improve data quality and enhance the conservation and use of plant genetic resources. They’re there (and here; what’s up with that?) to consult and make use of if you want.

Nibbles: Gene, Database, Climate Change, Nutrition, Archaeology, Website, Prices, Svalbard

Today’s maybe we’ll get some coverage if we link it to hunger and famine press release. Petunia gene.
Today’s there’s a database for that announcement. FAO’s Horticulture Cultivars Performance Database.
Today’s impact of climate change on X report. Forest resources in the Caribbean.
Today’s debunking a crappy piece of nutrition research killjoys. Experts respond to nutrition claims.
The Archaeobotanist has been going great guns; new book on domestication and millet domestication. We’ll pass on the museum post till we can firm it up.
IFPRI says let two flowers bloom. Here’s the super-groovy new policy kid on the block for non-policy wonks.
I’ll see your evil speculators and raise you a rising secular trend in food prices. (See what I did there?)
With a heavy clunk, The Economist gave Svalbard’s Doomsday Seed Vault a fine 4th birthday present.

Nibbles: African seeds, African needs, Egyptian seed preservation, Archaeocandy, Conservation, Seed swap site, Water buffalo genome, Anti-striga films, Entomophagy, Black sigatoka, Pavlovsk, Cannabis genome

Gates just gave AGRA $56 million to make new seed varieties available. PASS still not collecting the diversity it hopes to displace.
Hang on though. Africa needs a “Green renaissance, not revolution”.
Saving seeds the ancient Egyptian way.
Eating sweets the ancient Papuan (and others) way.
Odd to hear an agrobiodiversity dude talking about silver bullets – even with a question mark.
SeedZoo site offers a space to give and to receive “traditional and indigenous food plants from around the world”.
Today’s forthcoming genome of agricultural interest: water buffalo.
Farmer to farmer films – gender sensitive, natch – “fight against striga”.
Assessing the Potential of Insects as Food and Feed in assuring Food Security, from the FAO document repository.
Much sound, less light, on black Sigatoka disease, from the BBC (natch).
Vaviblog rounds up the latest skinny on Pavlovsk.
And speaking of Vavilov, the latest genome to be sequenced has a VIR connection.

Nibbles: Commons, Tom Wagner, CGIAR, Domestication presentation, Sophisticated urbanites, Vavilov’s potatoes in the news, Perennial crops, African drought, Aegean lathyrism, Heirlooms

The vocabulary of the commons.
An interview with Tom Wagner, a great tomato and potato breeder.
The CGIAR Consortium has a newsletter, with bits in it about what they’re doing on agrobiodiversity, genebanks (such as this one), all that stuff. But I guess news of this big Africa-wide food security project came in too late. Oh, here’s another one, on ICRISAT’s new chickpea.
Pat Heslop-Harrison on domestication. I am reliably informed he once extracted DNA from a fruit smoothie using nothing but household utensils and cleaning chemicals. Pat, is there a video?
Urban ag in the Philippines. For some reason, there’s been a ton of this sort of urban food stuff on the tubes lately. Like this for instance. And this (compare current orchards in London with historical ones). I may just have to blog about it. Oh dear, I just have.
The Glasgow Herald heralds the importance of Vavilov’s potatoes.
Long post with lots of different bits of info on lots of perennial crops.
Monitoring drought in Africa via pretty maps. And more pretty maps in search of a use.
Ancient Aegean lathyrism? Dirk alerted.
A keeper of seeds does his stuff near Pittsburgh.

Nibbles: NERICA vs landraces, Asian breeding, Wild wheat threats, Indian agrobiodiversity area, GBIF, Ancient Amazonia

NERICA shmerica.
Did you know that the Society for Advancement of Breeding Research in Asia and Oceania (SABRAO) 12th Congress from 13-16 January 2012 in Chiang Mai, Thailand. No, neither did I.
Whither wild wheat?
Koraput and its agrobiodiversity, including aus rice, makes it on the Globally Important Agricultural Heritage System (GIAHS).
GBIF has many duplicates. I’m shocked. Shocked, I tell you.
Amazonia was densely populated. No it wasn’t. Yes it was. No it wasn’t.
