Well this is something you don’t see every day.
Brainfood: Domestication, Maize roots, Dental calculus, Psychedelic drugs, Green manures, Forage millet, VIR radish, Wild beans, Siberian dogs, Maize taxi, Dairying history
- Reconsidering domestication from a process archaeology perspective. De-colonising, and de-transitivising, domestication.
- Maize biochemistry in response to root herbivory was mediated by domestication, spread, and breeding. Not archaeology, but an example of the more expansive view of domestication being touted above.
- Tracking the transition to agriculture in Southern Europe through ancient DNA analysis of dental calculus. Agriculture was associated with some changes in oral microbiomes, but not nearly as big as happened relatively recently. One could perhaps argue that some oral commensals were domesticated? No? Too much? More on dental calculus below…
- The Failed Globalization of Psychedelic Drugs in the Early Modern World. Culture and religion affected why tobacco spread around and peyote didn’t. Wait, domestication had nothing to do with it?
- Estimating agronomically relevant symbiotic nitrogen fixation in green manure breeding programs. All the better to domesticate them.
- Assessing Forage Potential of the Global Collection of Finger Millet (Eleusine coracana (L.) Gaertn.) Conserved at the ICRISAT Genebank. The top 10 identified, and they’re not bad, considering forage potential was not what the crop was domesticated for. ILRI unavailable for comment :)
- Genetic Diversity of Phenotypic and Biochemical Traits in VIR Radish (Raphanus sativus L.) Germplasm Collection. More variable than was once thought. Ah, domestication, you never disappoint…
- Preliminary evaluation of wild bean (Phaseolus spp.) germplasm for resistance to Fusarium cuneirostrum and Fusarium oxysporum. Wait, domestication can disappoint after all. Deeply. At least we still have the CWR.
- Not so local: the population genetics of convergent adaptation in maize and teosinte. People moved maize about, post-domestication, usefully bringing it into contact with teosinte. But the main author Dr Silas Tittes says it better. Hail the maize taxi!
- Modern Siberian dog ancestry was shaped by several thousand years of Eurasian-wide trade and human dispersal. People moved dogs about, post-domestication. The doggie taxi?
- Dairying enabled Early Bronze Age Yamnaya steppe expansions. People moved around because of milk. But the main author Dr Shevan Wilkin says it better, and links this with other important papers. Dental calculus never disappoints.
Nibbles: Pasta al forno, Polynesian dispersal, Ryan Phelan talk
- More evidence that some food staples are going to be in trouble.
- Samoa to Rapa Nui in 400 years. But the Americas before that? Mash up with banana, taro and sweet potato next.
- TED talk on genetic rescue.
Inhibiting biological nitrification in elite wheat
Many thanks to Victor Kommerell for pointing me to a new paper representing a sort of culmination of work that we first blogged about back in 2007. The older paper posed a question in its title: Can biological nitrification inhibition (BNI) genes from perennial Leymus racemosus (Triticeae) combat nitrification in wheat farming? The answer now seems to be a resounding maybe.
Smallholder access to seeds in Africa benchmarked
You’ll remember that the good people at Access to Seeds Index rate seed companies on how and to what extent they make their products available to smallholder farmer in developing countries. Today they launched the results for 32 companies working in Western and Central Africa. Here are the key findings (I’m quoting):
- Seed companies are active in almost all index countries across Sub-Saharan Africa and South and South-east Asia.
- Many companies are providing more diverse portfolios for vegetables and field crops but need to offer more pulses to help tackle malnutrition.
- Leading seed companies are offering extension services in more countries.
- Companies are still only concentrating their investments in infrastructure in a few countries.
But you want to know who did well in the rankings, right? Ok, here’s the Top 3.
Well done, Bayer, East-West and Novalliance.
