- 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.
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.
Brainfood: Mapping double, Niche modelling, CGIAR impacts, Pathogen genebank, Data stewardship, Breeding tradeoffs, Organic vs conventional, Agronomic trials, Teff evaluation, Eggplant genetic resources, Quinoa phenotyping
- Conservation needs to break free from global priority mapping. Couldn’t agree more. And less.
- National climate and biodiversity strategies are hamstrung by a lack of maps. Wait, what?
- The evolutionary genomics of species’ responses to climate change. You need to combine niche modelling with genetic adaptation to get the best maps.
- Payoffs to a half century of CGIAR research. A benefit-to-cost ratio (BCR) of 10:1. Not counting the genebanks. And all the maps.
- A case for conserving plant pathogens. But will it be worth it?
- Poor data stewardship will hinder global genetic diversity surveillance. What’s the BCR for decent metadata?
- Mitigating tradeoffs in plant breeding. Cutting out the cross-talk changes tradeoff to payoff.
- Comparing Productivity of Organic and Conventional Farming Systems: A Quantitative Review. Conventional is more productive. But should yield be the only criterion?
- Priority micronutrient density in foods. Right. Micronutrients are also important.
- Reconciling yield gains in agronomic trials with returns under African smallholder conditions. And how was yield measured anyway?
- Data-driven, participatory characterization of traditional farmer varieties discloses teff (Eragrostis tef) adaptive and breeding potential under current and future climates. This might well be an example of applying the lessons of the above.
- Genetic Diversity and Utilization of Cultivated Eggplant Germplasm in Varietal Improvement. The wild relatives will save us.
- Quinoa Phenotyping Methodologies: An International Consensus. But will it work for the wild relatives? Just kidding, this is an important development for another crop (with the above) which doesn’t have something like the CGIAR and its 10:1 BCR behind it…
Nibbles: Genebanks in Brazil, Tunisia, Ghana, Ethiopia, Goan rice, Wheat adoption, Peruvian hot peppers & cacao, Amazonian fruits and nuts, Dates, Great Hedge of India, Conservation genetics presentation
- Safety duplicating a chickpea collection.
- Tunisia’s genebank in the news.
- Ghana’s genebank trying to save taro.
- Using a genebank to improve Elephant grass.
- On-farm conservation of rice in Goa.
- Molecular tools show that a couple of varieties account for about half the wheat acreage in Bangladesh and Nepal. Hope all the landraces are in genebanks, and safety duplicated.
- Celebrating Peruvian pepper diversity.
- Peru’s cacao diversity doesn’t need help, apparently.
- However, the Amazon’s wild-extracted fruits (including cacao and a wild relative) could be in trouble. Hope they’re in genebanks, just in case.
- How the date came to the US. Including its genebanks.
- India had a precursor of the Green Wall of Africa but nobody remembers it. Glad it wasn’t used as a genebank of sorts.
- Conservation genetics (i.e., most of the above) explained in 48 slides.
Brainfood: Extreme events, Hot livestock, Decentralized breeding, Rice evaluation, Maize relatives double, Peanut hybrids, Tanzanian cassava, Microbiome, Brassica pests, Hop terroir, Beer taste
- Extreme climate events increase risk of global food insecurity and adaptation needs. Factoring in climate variability shows that just considering the change in the average climate underestimates the food security hit.
- Increases in extreme heat stress in domesticated livestock species during the twenty-first century. And the hit is already landing.
- Data-driven decentralized breeding increases prediction accuracy in a challenging crop production environment. What we therefore need is 3-D breeding.
- Novel Sources of Pre-Harvest Sprouting Resistance for Japonica Rice Improvement. Including for resistance to pre-harvest sprouting in rice due to unexpected typhoons.
- The genome of stress tolerant crop wild relative Paspalum vaginatum leads to increased biomass productivity in the crop Zea mays. For sure crop wild relatives are going to help.
- Megabase-scale presence-absence variation with Tripsacum origin was under selection during maize domestication and adaptation. If they haven’t helped already.
- Registration of three peanut allotetraploid interspecific hybrids resistant to late leaf spot disease and tomato spotted wilt. Sometimes you need multiple CWR.
- Collection, genotyping and virus elimination of cassava landraces from Tanzania and documentation of farmer knowledge. But landraces too will come in handy, especially if farmers’ knowledge is properly documented.
- Prioritizing host phenotype to understand microbiome heritability in plants. And don’t forget the microbiome.
- Economic analysis of habitat manipulation in Brassica pest management: Wild plant species suppress cabbage webworm. Not to mention the ecosystem as a whole.
- Relevance of hop terroir for beer flavour. Oh hell, I give up, time for a craft beer.
- On the Trail of the German Purity Law: Distinguishing the Metabolic Signatures of Wheat, Corn and Rice in Beer. Maybe even a weissbier.
