- A global-scale expert assessment of drivers and risks associated with pollinator decline. “Key findings: 1) risks to human well-being from pollinator decline are higher in the Global South; 2) there is a clear lack of knowledge about pollinator decline in Africa; 3) loss of managed pollinators (e.g. honey bees) is only a serious risk to people in North America.” That’s according to the main author Dr Lynn Dicks on Twitter.
- Agrochemicals interact synergistically to increase bee mortality. Stress on pollinators is more than the sum of its parts.
- Evolutionary innovations driving abiotic stress tolerance in C4 grasses and cereals. Major C4 crops need more stress.
- Deep scoping: a breeding strategy to preserve, reintroduce and exploit genetic variation. You may not need a separate pre-breeding programme to introduce new diversity into your breeding programme without wrecking it.
- Genomic resources for lupins are coming of age. Maybe we could have a pre-breeding programme now?
- Six new species of coffee (Coffea) from northern Madagascar. Including 4 really narrow endemics. I wonder what they taste like. Start evaluation and pre-breeding?
- Refugee camps and deforestation in Sub-Saharan Africa. Much, much less of an impact that you’d think.
- Suitability of root, tuber, and banana crops in Central Africa can be favoured under future climates. More than you’d have thought.
- Proportional sampling strategy often captures more genetic diversity when population sizes vary. Sample more than you normally would from bigger populations of rare wild species.
- Plant pathogen infection risk tracks global crop yields under climate change. Where yields go up, fungal/oomycete infection risk goes up; where yields go down, so does infection risk. Assemblages will change especially in temperate regions.
- Developments in Subsistence Practices from the Early Bronze Age through the Iron Age in the Southern Levant. From pigs, wild animals and emmer to zebu, camelids, and free-threshing wheats.

- A global database of diversified farming effects on biodiversity and yield. Always good to have the data.
- Dietary agrobiodiversity for improved nutrition and health outcomes within a transitioning indigenous Solomon Island food system. Maybe we should have a database of diversified farming effects on health and nutrition too?
- Exploring ‘beyond-food’ opportunities for biocultural conservation in urban forest gardens. Always good to have more trees.
- Community seed network in an era of climate change: dynamics of maize diversity in Yucatán, Mexico. Always good to have landraces. And neighbours.
- Microbe-dependent heterosis in maize. Maize hybrids need microbes.
- Assessment of genetic diversity and population structure of oil palm (Elaeis guineensis Jacq.) field genebank: A step towards molecular-assisted germplasm conservation. 30% seems a lot for a core collection. But it’s good to have the data.
- Sources of resistance to Pseudocercospora fijiensis, the cause of black Sigatoka in banana. 11 resistant accessions out of 95 seems pretty good, on the other hand.
- GWAS unveils features between early- and late-flowering pearl millets. Based on a national-level core collection in Senegal. Presumably this will scale?
- Germplasm Collection, Genetic Resources, and Gene Pools in Alfalfa. Lots of work has been done. More work is needed on the wild relatives though.
- Assessment and modeling using machine learning of resistance to scald (Rhynchosporium commune) in two specific barley genetic resources subsets. Fancy maths helps to identify the barley genebank accessions you really need.
- Strategic malting barley improvement for craft brewers through consumer sensory evaluation of malt and beer. More fancy maths, this time applied to a hedonic data in the service of beer. Germplasm evaluation we can all get behind. No FIGS, alas.
- Large-scale whole-genome resequencing unravels the domestication history of Cannabis sativa. 4 genetic groups: primordial (located in China, not Central Asia, and going back 12,000 years), 2 medicinal, 1 fibre. Now for the hedonic evaluation.
- The Origins of the Apple in Central Asia. Probably domesticated to cope with the munchies.
- Genetic Divergence and Population Structure in Weedy and Cultivated Broomcorn Millets (Panicum miliaceum L.) Revealed by Specific-Locus Amplified Fragment Sequencing (SLAF-Seq). There are interesting genetic differences between wild and feral forms, and between eastern and central-western cultivated forms. The Silk Road trifecta.
- Global range expansion history of pepper (Capsicum spp.) revealed by over 10,000 genebank accessions. Spoke too soon. The Silk Road had a role in pepper movement too. Among other trade routes. Interesting, and unsurprising, that genes for pungency show distinct geographic patterns.
- Genomic evidence supports an independent history of Levantine and Eurasian grapevines. First domestication in the Caucasus, and then in the Levant, but not clear if from local sources. No word on hedonic evaluation.
- Genotyping-By-Sequencing diversity analysis of international Vanilla collections uncovers hidden diversity and enables plant improvement. Belize seems to be a real hotspot. The Silk Road not involved.
Nibbles: Deforestation, Grizzly genetics, Animal domestication, Wheat drones, Okra experiments, Millet survey, The Common Table
- 26 million hectares of forest were lost in 2020.
- Genetic groups in grizzly bears line up with Indigenous languages in British Columbia. How about the trees, though?
- But why weren’t grizzly bears domesticated? Because they’re not friendly, feedable, fecund and family-friendly.
- Drones and wheat breeding.
- Crowdsourcing okra evaluation. No drones involved.
- Health-conscious urban Indians eat millet for health reasons. Goes great with okra.
- The Common Table: sharing stories about reforming the food system. Like a couple of the above.
Nibbles: Training materials double, Tree platform double, Wild rabbit, Economic value
- Crawford Fund training materials for high schools include discussion of genebanks.
- And that would go quite well with this graphic novel on natural selection in Mimulus from Health in Our Hands.
- There’s a Global Tree Knowledge Platform from ICRAF…
- …which could probably be usefully mashed up with the restoration platform Restor.
- The Sumatran striped rabbit makes a rare appearance. On Facebook.
- The World Bank makes the economic case for all of the above. Well, maybe except the Sumatran rabbit.
Brainfood: Bambara groundnut, Germination prion, Future foods, Hotspots, Soybean expansion, Remote sensing, Micronutrients, Madagascar food security, Aromatic maize, Sunflower oil, Grasspea, ICARDA lentils, Australian wild rice
- Bambara Groundnut (Vigna subterranea [L.] Verdc.) Production, Utilisation and Genetic Improvement in Sub-Saharan Africa. Needs breeding for better yield and nutritional value, and there’s plenty of diversity to work with.
- A prion-like protein regulator of seed germination undergoes hydration-dependent phase separation. And variation may be linked to ecological adaptation, and so could be used in breeding for drought tolerance. Possibly even in Bambara groundnut?
- Future foods for risk-resilient diets. Yeah, microalgae, mycoprotein and mealworm, what could possibly go wrong? I almost prefer the prion.
- Hotspots of land-use change in global biodiversity hotspots. Agricultural expansion is the main threat in the Global South, urbanization in the North. Bring on the microalgae.
- Massive soybean expansion in South America since 2000 and implications for conservation. A lot of it happens on pastures, but not all, and those cows have to go somewhere.
- Remote sensing of biodiversity: what to measure and monitor from space to species? How the above was done. Still waiting for my landrace erosion early warning system.
- Priority micronutrient density in foods. Organs, small fish, dark green leafy vegetables, shellfish, beef, goat, eggs, milk, cheese, and canned fish with bones. What, no microalgae?
- Food insecurity related to agricultural practices and household characteristics in rural communities of northeast Madagascar. Diversification is needed. Have they thought of microalgae?
- Creation of aromatic maize by CRISPR/Cas. Because it’s there? Since you’re at it, why not aromatic microalgae?
- Genotyping and lipid profiling of 601 cultivated sunflower lines reveals novel genetic determinants of oil fatty acid content. Analysis of lots of Russian material identifies interesting genomic regions. Hold the microalgae.
- Study of Knowledge, Attitude, and Practice in Participants with Regular Intake of Lathyrus, But No Spastic Paraparesis. Neurolathyrism is not a problem even where grasspea is a major crop.
- Genetic diversity and GWAS of agronomic traits using an ICARDA lentil (Lens culinaris Medik.) Reference Plus collection. Who needs grasspea, though, eh, when you have lentils?
- Starch structure-property relations in Australian wild rices compared to domesticated rices. Good, and good for you. Keep your microalgae.
