Chefs help conserve peanut butter and jelly sandwiches
I believe we have Nibbled both of these articles, but I think they could stand another few minutes in the limelight. One describes how self-described “farmer-scientist” Dr Brian Ward of Clemson University — with a little help from his friends — is bringing back from near extinction a peanut variety called Carolina Africa Runner:
Luckily, in the 1940s North Carolina State University collected samples of a variety of peanuts during a breeding program, and the Carolina’s germplasm was preserved.
The second article is about maverick Washington State University breeder Dr Stephen Jones’s attempts to come up with better tasting bread.
Several years ago, he started a project called the Bread Lab, a Washington State program that approaches grain breeding with a focus on the eventual culinary end goal. The idea came about because Jones says he was tired of the USDA and Big Ag dictating the traits that he needed to breed for. “They would tell us [a certain wheat variety] doesn’t make a good loaf of bread. Well, what they meant was an industrial, high-speed, mixing, full of junk, white — just lily-white — bread,” Jones says. “And we didn’t want that opinion, so we had nowhere to go.”
WhatOne of the several things the stories have in common is the involvement of chefs. Now, there must also be one out there interested in heirloom fruits. Then we could bring them all together…

All maize, all the time
Lots on maize on the interwebs lately. First, there was a Nature Plants paper on the origin of the crop in the southwestern US, comparing DNA from ancient cobs with that from Mexican landraces:
“When considered together, the results suggest that the maize of the U.S. Southwest had a complex origin, first entering the U.S. via a highland route about 4,100 years ago and later via a lowland coastal route about 2,000 years ago,” said Jeffrey Ross-Ibarra, an associate professor in the Department of Plant Sciences.
A separate article in the journal summarized the results and set them in a wider context:
As genomic and palaeo-genomic studies have become more common, it has become increasingly clear that virtually every domestic plant and animal has incorporated genomes of numerous populations, including many that were not involved in the original domestication process. For example, although grapes, apples and pigs were domesticated outside of Europe, admixture with native wild European species has been so significant as to obscure the geographic origins of the modern domestic populations.
Meanwhile, the controversy over how to measure genetic erosion in maize continues, though I’m afraid in this case only the extract is free.
Which all means that the rather nice learning resource on maize domestication at the University of Utah, which I coincidentally recently came across, may need to be tweaked a bit.
Incidentally, if you plug Zea into the Native American Ethnobotany database at the University of Michigan, also a serendipitous find over the holidays, you’ll see that maize was far from being just a food plant.
There are even a couple of historical maize specimens included in the beta version of the new data portal of the Natural History Museum in London, which seems to be getting the softest of launches just now. Great to browse through. Not sure what kind of launch Brazil’s new(ish) biodiversity information system (SiBBs) got, but it too features maize records, over 400 in this case, though only 10 georeferenced. The source of most is given as “Dados repatriados – United States (no coordinates)”, which means that they came from GBIF, and in the case of maize are probably therefore mostly from GRIN. As I said a couple of posts ago for wheat, data sure does get around online.
