Nibbles: Potato, Research, Tobacco, Bees squared, Seed diversity, Declaration
- “The Jersey Royal is the only potato that enjoys protected designation of origin…”
- Agricultural research not enough?
- Wild crop relative switches pollinator to escape nasty caterpillars.
- Bushmeat hunters become beekeepers.
- And here’s why beekeeping is such a good thing.
- Diversity deemed a good thing, even for crazed monoculturists.

The tribe of genebankers gets a visit
Peter [Curran] meets the botanists who won the lottery. Seed conservation used to be rather marginal to the main scientific activity at The Royal Botanic Gardens at Kew. That is, until, the scientists who preserve seeds for future generations asked for and received 30 million pounds.
It’s a BBC programme and you have 7 days left to listen to it. It provides an interesting insight into a particular, albeit unique, genebank — if you can get past Mr Curran’s sardonic attitude.
Nibbles: Cassava, fonio, apples, Salicornia, aurochs, seeds
- Nagib Nassar challenges the wisdom of GM cassava. Cultivate indigenous and wild varieties of the crop!
- Or fonio (Digitaria exilis). New paper on its diversity.
- And for dessert? Wild apple diversity?
- Need salad? How about Salicornia then?
- Nice aurochs steak to go with the salad?
- Not too soon to start planning a future harvest, if you’re in Ireland and want seeds.
Locating agricultural origins in Mexico and Italy
I know that domestication is not an event, but a process. I know that most crops and livestock were probably domesticated more than once, in more than one area. I know all this, but I’m still a sucker for papers that come up with specific times and places for the origin of agriculture. Papers such as Daniel Zizumbo-Villarreal and Patricia Colunga-GarcíaMarín‘s in the latest GRACE:
Sympatric distribution of the putative wild ancestral populations of maize, beans and squash indicate the extreme northwest Balsas-Jalisco region as a possible locus of domestication.
The paper is a review. It synthesizes a host of paleoecological, archaeobotanical and molecular data. Meanwhile, another paper, this time in the Journal of Archaeological Science, applies matrix mathematics to a somewhat different, though related, problem: the arrival of wheat in Italy. The authors looked at a selection of old emmer landraces from all around Italy stored in the German and ICARDA genebanks. 1 They developed a matrix of genetic distances among these based on microsatellite data. They then calculated matrices of geographical distances among the landraces based on different putative places of arrival of the crop around the coast of Italy. The two matrices showed the closest correlations for arrival sites located in northern Puglia, the heel of Italy. That corresponds with where the earliest Neolithic sites are found.
Now, I wonder, when will someone apply this method to maize, beans and squash molecular data and test mathematically Zizumbo-Villarreal and Colunga-GarcíaMarín more “qualitative” inferences?
