- Carotenoid profiling in tubers of different potato (Solanum sp) cultivars: Accumulation of carotenoids mediated by xanthophyll esterification. 60 cultivars, including landraces, fall into 3 main groups. Need to keep an eye out for those xanthophyll esters.
- Buckwheat honeys: Screening of composition and properties. In other news, there is monofloral buckwheat honey in Italy and E. Europe. But not as much as the producers say.
- Using geotagged photographs and GIS analysis to estimate visitor flows in natural areas. Very cool, but try as I might I cannot think of an application in agricultural biodiversity conservation. Maybe you can.
- Quiet sustainability: Fertile lessons from Europe’s productive gardeners. Food gardening in Europe’s cities is not about an “urban peasantry” putting essential food on the table. And it’s not about expousing a yuppie alternative lifestyle. It’s just about the sheer fun of it.
- Introgression and the fate of domesticated genes in a wild mammal population. Coat colour polymorphisms in wild Soay sheep was caused by admixture with more modern breed 150 years ago.
- Catholicism and Conservation: The Potential of Sacred Natural Sites for Biodiversity Management in Central Italy. So apparently there’s a “common view that Christianity is anti-naturalistic.” Well, it’s wrong. What’s Christianity’s view of agrobiodiversity, I wonder?
- Comparative transcriptomics reveals patterns of selection in domesticated and wild tomato. DNA differences due to selection at 50 genes, transcription differences at thousands.

- Setting up a network of high potato diversity sites for in situ conservation. It has a Facebook page, so “Like” it.
- Some of that diversity will no doubt find its way to Lima’s markets.
- If not, Leaping and Learning will tell you how. And why.
- There’s a lot of diversity in genebanks too, of course. And thank goodness for that!
- Potatoes are important in Africa too.
- And Japan. But do they go with eels?
- What are potatoes like for micronutrients? Probably better than you think. But could be better?
- If not, you can always pickle them. Can’t you?

- Rethinking rice-based agriculture in Assam.
- And China, maybe?
- By breeding your way out of the problem, maybe?
- And then patenting the result? Well, maybe not.
- Here comes fair-trade quinoa.
- Nordic cheeses to go with those insects from a few days back. Lack of Norwegian representation pointed out, as well as a remedy.
- I wonder how many Italian cheeses are made from the milk of endangered breeds. Well, now the relevant association has a Facebook page, so I can ask them.

Varieties of climate change
Something is up, no doubt about it. First off, PBS in the US has a longish news report on how farmers in India “find promise in ancient seeds”.
Watch Struggling Farmers in India Find Promise in Ancient Seeds on PBS. See more from PBS NewsHour.
Strangely, although the farmers are able to find promise in ancient seeds, the report claims that seeds stored at IRRI in the 1960s are too ancient to be viable. Not sure how that works.
One of the protagonists of the PBS video, Debal Deb, crops up again in another video that came to light on the PAR website. According to PAR: “This film follows the construction of a new seed bank premises in Odisha, a venture that provides a potent symbol of Debal’s values”.
With the zeitgeist firmly embracing the idea of agricultural biodiversity, preferably ancient agricultural biodiversity, as a suitable response to climate change, it is good to be reminded that droughts are diverse too. David Lobell looks at two recent scientific papers on drought tolerance. One shows very little difference between specifically “drought-tolerant” maize varieties and other varieties without the drought-tolerance genes.
To me, there are a couple of possible ways to interpret this. One is that the newer varieties being marketed by companies are not really much better in general. Or these results might indicate that the types of droughts the newer varieties were designed for are somehow different than the type of droughts they were exposed to in this experiment. In particular, as we’ve discussed in prior posts, 2012 was a drought characterized by very high temperatures and vapor pressure deficits, the kind of droughts that one expects more of with climate change.
2012, in other words, was not just a dry drought but a hot drought. The other study David looks at compares the two kinds of drought.
What’s really interesting is how remarkably low the correlation between performance in “drought” and “drought+heat” is (0.08).
While not reading too much into either study, Lobell cautions that very hot droughts may require different kinds of varieties from mere dry droughts.
