- 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.

- The hidden treasure of Colombian potatoes. In a lad mag, no less.
- Umbrian olive terraces get UN status, no less.
- Maize furniture, no less.
- New wild tea species found. In protected areas, 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.
- Updated review of potential medicinal genetic resources in the USDA, ARS, PGRCU industrial and legume crop germplasm collections. 22 species have potential.
- Apple (Malus spp.) Breeding: Present and Future. It’s bright, apparently.
- Strategies for Olive (Olea europaea L.) Breeding: Cultivated Genetic Resources and Crossbreeding. There’s an International Olive Council, and it has a Network of Germplasm Banks.
- Genetic flow among olive populations within the Mediterranean basin. Separate Syrian and Algerian genepools.
- Traditional farmers’ varieties: a valuable source of genetic variability for biofortification programs. Back to the future.
- SDG 2.5: How Policies Affecting Trade and Markets Can Help Maintain Genetic Diversity. It’s possible, but not automatic.
- 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:

A focus on West Africa
A paper just out on the domestication of pearl millet gives me the chance to acknowledge the terrific amount of work on domestication of West African crops going on in Yves Vigouroux‘s lab.
