The olive’s second act?
Is Xylella — cause of the olive plague that has been stalking southern Europe for a decade — a blessing in disguise for the Salento? Jeremy asks the hard questions in his latest Eat This Podcast. Spoiler alert: Silvestro Silvestori thinks it might just be:
…at the heart of Xylella and the Salento is an identity crisis, that we’re all the children of farmers, we’re all farmers ourselves. And for most people, that’s not the case any longer. And there’s not a lot of industry left here as far as farming. So I think first we have to look at ourselves in the mirror and say, what are we?
Fascinating insights throughout, so listen to the whole thing. And wonder whether this will help.

- Deep genotyping reveals specific adaptation footprints of conventional and organic farming in barley populations — an evolutionary plant breeding approach. An initial, diverse barley population is allowed to adapt to contrasting organic and conventional conditions for 2 decades and diverges considerably genetically as a result. Don’t need AI to predict that. Perhaps more surprisingly, analysis suggests organic-adapted populations need to be selected for root traits to catch up in yield.

- The authors of book “Moving Crops and the Scales of History” have been awarded the Edelstein Prize 2024 for their work to “redefine historical inquiry based on the ‘cropscape’: the assemblage of people, places, creatures, technologies, and other elements that form around a crop.” Let’s see how many cropscapes we can come up with today.
- Here’s one. The Ecuador cacao genebank gets some much-needed help.
- Digging into Nigerian yams. And another.
- Castle Hex has a programme on Lima beans on 7-8 September. Sounds like fun.
- What if you can’t work out what the crops are, though? As in Mesopotamian recipe books, for example.
- The community seed banks of Nepal have a new website. Good news for those Nepalese cropscapes.
- A new project is testing RNA integrity number (RIN) as a metric of seed aging for a bunch of rare wild plants. One day maybe community seed banks will be using it.
- China has inventoried its agricultural germplasm. Will it be applying RIN next?
- The French are using bandes dessinées to teach about cryopreservation of animal genetic resources. Livestockscapes?

Not Your Usual Potatoes
Jeremy’s latest newsletter discusses a very humble wild potato species, which we have actually blogged about here on a number of previous occasions. Do subscribe, there’s other cool stuff in there.
Indigenous people in the southwest of North America had more of a hand in crop domestication than is often thought, according to a new paper on the Four Corners potato, Solanum jamesii. So much so, according to the press release I read, that the results “support the [uncited] assertion that the tuber is a ‘lost sister,’ joining maize, beans and squash—commonly known as the three sisters—as a staple of crops ingeniously grown across the arid landscape”.
The release explains that populations of Four Corners potato, found, naturally enough, in the areas where Arizona, Utah, Colorado and New Mexico meet, fall into two distinct types. Some — archeological populations — grow within 300 metres of an archaeological site and are relatively small. The rest are non-archaeological and widely spread throughout the species’ range. Sampling the DNA of both types, the researchers discovered much more diversity in the non-archaeological populations than in those associated with settlements, which suggests domestication by local people.
Researchers were also able to show that specific archaeological populations were most like non-archaeological populations quite some distance away, which means that transport networks among the indigenous people were well developed. Settlement sites in the southwest of Utah were around 500 km from the nearest natural populations from which they might have been derived.
S. jamesii contains double the protein, calcium, magnesium, and iron of more familiar potatoes (S. tuberosum). The archeological populations were, however, not within the species’ central range, where the wild populations are much larger and more productive. So did people transport and grow the tubers simply to have a nourishing source of food close at hand in winter? That would be cultivation. Or were they, as seems likely, also actively selecting for things like taste, size and frost tolerance, which would put them well on the way to domestication? More detailed DNA might studies provide an answer.
A further thought. Four Corners potato, which is still grown by some Diné people (and probably others), copes well with drought and heat. Might it also have a wider market?
