- Tracking the adoption of bread wheat varieties in Afghanistan using DNA fingerprinting. 75% of samples were varieties released after 2000, landraces are being replaced, and farmers name varieties correctly about 50% of the times.

- Estimated six per cent loss of genetic variation in wild populations since the industrial revolution. The new 75%.
- Eating Healthy or Feeling Empty? How the “Healthy = Less Filling” Intuition Influences Satiety. Healthier food is perceived as less filling, unless it’s described as nutritions. People are strange.
- What is the cost of integration? Evidence from an integrated health and agriculture project to improve nutrition outcomes in Western Kenya. Not insignificant, but worth it.
- Traditional utilization and management of wild Allium plants in Inner Mongolia. 38 species, no less; many uses, much threatened.

US$ 67 million in from Gates Foundation, US$ 3.2 billion out in certified seed alone. Read the whole special issue for more. All starts with genebanks, though, doesn’t it. Doesn’t it? Hello? Is there anyone out there? Is this thing on?

- Efficiency of insect‐proof net tunnels in reducing virus‐related seed degeneration in sweet potato. “Seed” meaning vines. And yes, those tunnels work.
- Divergence with gene flow is driven by local adaptation to temperature and soil phosphorus concentration in teosinte subspecies (Zea mays parviglumis and Zea mays mexicana). Genetic differences between the two subspecies is maintained by adaptive divergence despite gene flow.
- Agronomic Performance and Nitrogen Fixation of Heirloom and Conventional Dry Bean Varieties Under Low-Nitrogen Field Conditions. Not much difference, which is actually interesting.
- Evolutionary Insights into the Nature of Plant Domestication. It’s a long process, in which natural selection and interspecific hybridization play an important part, involving many of the same genes across species.
- Cryptic genetic variation accelerates evolution by opening access to diverse adaptive peaks. Add to the above? Ah no, only in bacteria so far.
- Screening African rice (Oryza glaberrima) for tolerance to abiotic stresses: III Flooding. From a collection of >2,000 to 11 better than Asian rice. You’re wondering about I and II, aren’t you?
- Understanding the factors influencing fall armyworm (Spodoptera frugiperda J.E. Smith) damage in African smallholder maize fields and quantifying its impact on yield. A case study in Eastern Zimbabwe. Differences among maize varieties, but weeding, tillage and intercropping also have an effect. Have yield losses been overestimated, though? Maybe.
- Natural selection contributed to immunological differences between hunter-gatherers and agriculturalists. But the evidence seems to be that the pathogen burden was higher for the hunter-gatherers, which goes counter to everything we’ve been taught by Jared Diamond.
- Increasing crop heterogeneity enhances multitrophic diversity across agricultural regions. More crops means more biodiversity in general.
- More Than the Sum of Its Parts: Microbiome Biodiversity as a Driver of Plant Growth and Soil Health. More microbes mean better plant growth.
- Science–graphic art partnerships to increase research impact. Free your inner artist.
- Genetic diversity, linkage disequilibrium, and population structure analysis of the tea plant (Camellia sinensis) from an origin center, Guizhou plateau, using genome-wide SNPs developed by genotyping-by-sequencing. Four groups: pure wild type, admixed wild type, ancient landraces and modern landraces.
- The Relative Caloric Prices of Healthy and Unhealthy Foods Differ Systematically across Income Levels and Continents. …and at least partially explain differences in undernutrition and overweight in adults. Here’s the infographic.
- Household-level drivers of dietary diversity in transitioning agricultural systems: Evidence from the Greater Mekong Subregion. It’s complicated and context-specific, but dietary diversity seems to generally increase with agricultural “development,” i.e. market orientation, specialisation, and intensification. Somewhat surprising? I’ve lost track, frankly.
- Potential role of neglected and underutilized plant species in improving women’s empowerment and nutrition in areas of sub-Saharan Africa. So is increasing cultivation of orphan crops a driver or a consequence of agricultural development? See what I mean? Anyway, useful review.
