- Foods and fads: The welfare impacts of rising quinoa prices in Peru. Modest.
- Measuring the Affordability of Nutritious Diets in Africa: Price Indexes for Diet Diversity and the Cost of Nutrient Adequacy. Maybe they could try quinoa.
- Impacts of climate warming on terrestrial ectotherms across latitude. Insects are in trouble in the tropics, but will make up for it at higher latitudes, which will be really bad for crops there, 10-25% more bad.
- Evidence that organic farming promotes pest control. Something for farmers in those higher latitudes to think about.
- The global distribution of Bacillus anthracis and associated anthrax risk to humans, livestock, and wildlife. 63.8 million rural poor livestock keepers are at risk. No word on effect of climate change.
- Do open-pollinated maize varieties perform better than hybrids in agroforestry systems? Maybe in Rwanda, but in Ethiopia not so much.
- More than Yield: Ecosystem Services of Traditional versus Modern Crop Varieties Revisited. Landraces are liked for yield stability in marginal environments, and for cultural reasons.
- Root and shoot traits in parental, early and late generation Green Revolution wheats (Triticum spp.) under glasshouse conditions. Modern wheat have smaller roots.
- Standardized reporting of the costs of management interventions for biodiversity conservation. Behind a paywall, so can’t tell whether includes genebanks. But I bet it doesn’t. Tell me I’m wrong.
- Global assessment of agricultural system redesign for sustainable intensification. Apparently 30% of farms and 10% of agricultural land worldwide, which is both more and less than I would have guessed.
- Genetic homogeneity of North-African goats. The Berber breeds are different, everything else is a big mixed up mess.
- Plant domestication decreases both constitutive and induced chemical defences by direct selection against defensive traits. In cabbage, even the tissues that are not eaten are more edible than in the wild relative.
- Polyploid plants have faster rates of multivariate climatic niche evolution than their diploid relatives. Relevant for domestication?
- An Initiative for the Study and Use of Genetic Diversity of Domesticated Plants and Their Wild Relatives. In Mexico.
- Population structure, relatedness and ploidy levels in an apple gene bank revealed through genotyping-by-sequencing. There’s a lot of inter-relatedness in the Danish collection.
- Biases induced by using geography and environment to guide ex situ conservation. “Although geographic and environmental diversity have proven to be reliable predictors of allele frequency differences and ecotypic differentiation across species ranges, they appear to be poor predictors of allelic diversity per se.” At least for 3 species.
- Examining the spectra of herbarium uses and users. Herbaria mostly used by taxonomists shock.
- Ancient herders enriched and restructured African grasslands. Shit. You heard me.
Brainfood: Food as art, Maize seed, Jatropha genome, Wild camelids, Global nutrition, Price shocks, Pearl millet domestication, Yam domestication, NNL, New beer microbe, Dog coat colour, Herbarium biases, Maize N fixation
- Food as a daily art: ideas for its use as a method in development practice. Food can bring traditional and scientific knowledge together in an smorgasbord of ideas.
- Maize seed systems in different agro-ecosystems; what works and what does not work for smallholder farmers. Sure, purchasing hybrids from the formal sector seed system is gaining ground in Malawi, Zambia, and Chiapas, but not for home consumption, and only in high potential areas.
- Genome sequence of Jatropha curcas L., a non‐edible biodiesel plant, provides a resource to improve seed‐related traits. Is Jatropha even still a thing?
- Comparing genetic diversity and demographic history in co-distributed wild South American camelids. Vicuña (alpaca wild relative) display lower genetic diversity within populations than guanaco (llama) but more structure across Peru; strong bottlenecks happened at different times, but in both cases much later than domestication and before Spanish conquest.
- The Global Nutrient Database: availability of macronutrients and micronutrients in 195 countries from 1980 to 2013. Supply of micronutrients has increased during the period globally and across levels of development.
- Effects of Food Prices on Poverty: The Case of Paraguay, a Food Exporter and a Non-Fully Urbanized Country. Food price hikes are, overall, bad for everyone, but least bad for the poorest and richest.
- A western Sahara centre of domestication inferred from pearl millet genomes. Harlan’s non-centre not found. Free-to-read.
- Molecular basis of African yam domestication: analyses of selection point to root development, starch biosynthesis, and photosynthesis related genes. Domestication of wild yams was all about learning to grow in full sunlight, and it involved losing 30% of their diversity. But remember current wild yams are not all that wild.
- No net loss for people and biodiversity. How to ensure that people really are no worse off after an offset intervention.
- Identification of a novel interspecific hybrid yeast from a metagenomic open fermentation sample using Hi-C. Doesn’t work on its own, though.
- Length variations within the Merle retrotransposon of canine PMEL: correlating genotype with phenotype. Mobile DNA gets everywhere.
- Widespread sampling biases in herbaria revealed from large‐scale digitization. Blame mega-collectors.
- Nitrogen fixation in a landrace of maize is supported by a mucilage-associated diazotrophic microbiota. In aerial roots, no less.

- Phylogeny and genetic structure in the genus Secale. The perennial species is different from the annuals, which are divided into an Asian and a non-Asia group and show all kinds of introgression.
- Consumers’ acceptance of a local landrace: the case of purple carrots. Sure, if produced locally.
- Saving the breeds: German Farmers’ preferences for Endangered Dairy Breed conservation programs. Sure, if they get paid.
- Analysing innovations among cattle smallholders to evaluate the adequacy of breeding programs. Intensification will need more than selection within the local breed. But it’s a start.
- Genetic diversity and population structure of the USDA sweetpotato (Ipomoea batatas) germplasm collection using GBSpoly. 4 clusters: Central American, North American, South American, and others.

- Concept and protection of traditional knowledges in agricultural heritage system: a case study of Pu’er Traditional Tea Agrosystem. Based on 269 pieces of traditional knowledge, and in trouble.
- Mining alfalfa (Medicago sativa L.) nodules for salinity tolerant non-rhizobial bacteria to improve growth of alfalfa under salinity stress. They work even on their own.
- Frozen fungi: cryogenic storage is an effective method to store Fusarium cultures for the long‐term. I guess will also work on the above?
- DNA barcoding to promote social awareness and identity of neglected, underutilized plant species having valuable nutritional properties. Familiarity breeds contentment.
N-fixing maize goop
The news that a maize landrace has been found to fix atmospheric nitrogen because of microbes growing in gunk on its aerial roots has been getting a lot of traction. Understandably. The best take on it I’ve come across is this Twitter thread from Dr Sarah Taber:

- Toward improving photosynthesis in cassava: Characterizing photosynthetic limitations in four current African cultivars. The landraces are better at photosynthesis than the improved cultivars. Maybe because the aim of producing the latter was pest and disease resistance rather than yield.
- Ecogeography of teosinte. Only 11% in protected areas.
- A map of climate change-driven natural selection in Arabidopsis thaliana. Summer is coming.
- Urban backyards as a new model of pineapple germplasm conservation. Two thirds of citizen scientists did a really good job.
- Identification of unknown apple (Malus × domestica) cultivars demonstrates the impact of local breeding program on cultivar diversity. 330 unknown highly diverse trees in northern Minnesota, 264 unique genotypes, 76 matched to 20 named cultivars from local breeding program at the University of Minnesota, or imported Russian cultivars.
- Development of national crop wild relative conservation strategies in European countries. 30 countries: 13 in preparation stage, 14 with drafts, and 3 not yet started.
- Current knowledge and breeding perspectives for the spider plant (Cleome gynandra L.): a potential for enhanced breeding of the plant in Africa. I actually like the bitterness of the leaves.
