- 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.

- Wanna work in a genebank in Niamey?
- More on that proposed livestock genebank in Uganda.
- Microbes have collections too.
- On his holiday, Jeremy mainly looked at dead olive trees. Freak.
- The Potato King looks like a cool movie. Chef Ramsey’s latest? Maybe not so much.
- Oh crap, we missed National Potato Day. Not in Peru, settle down.
- More chefs, this time fiddling with rice in Tanzania, of all places.
- Will they do wild rice next?
- Peas getting a chance. But are they going to get inflatables like these bean varieties?
- But does it qualify as underutilized still, I wonder?
- Get to grips with brambles. The whole series is worth following.
- TR4 reaches South America’s bananas. Be afraid.
- Climate change will affects the region’s rainfed maize too.
- You’ll want sustainably sourced breakfast cereals to put those non-existent bananas on. Hey, companies, what about conserving genetic diversity along with that soil?

- From landraces to improved cultivars: Assessment of genetic diversity and population structure of Mediterranean wheat using SNP markers. Landraces cluster geographically, modern varieties by breeding programme.
- Global evidence of positive biodiversity effects on spatial ecosystem stability in natural grasslands. Higher species richness increases productivity in low-productivity communities, decreases it in high-productivity.
- Understanding the consequences of changes in the production frontiers for roots, tubers and bananas. Forget marketing, focus research on productivity.

- Mortality impact of low annual crop yields in a subsistence farming population of Burkina Faso under the current and a 1.5°C warmer climate in 2100. Low production in any given year responsible for considerable child mortality, which is likely to double because of climate change. If nothing is done.
