- 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.
Nibbles: Apple diversity, Quinoa diversity, Potato diversity, Indian coconut, Mead recipe
- The need to diversify apple breeding.
- Unlikely pean to the world quinoa core collection. I believe we may have blogged about it.
- And the Commonwealth Potato Collection rounds off today’s trifecta of cool genebanks.
- Kerala’s coconut problems only start with root wilt. Aren’t there coconut collections that could be used to solve them? Well of course there are.
- Recreating bochet, a medieval mead, sounds really hard, but worth it. Someone want to start a mead collection?
Nibbles: ISSS, SeedWorld, Farmers Pride, GRIN-U, Indian rematriation, NZ potatoes, European farming
- 13th Triennial Meeting of the International Society for Seed Science: Note in particular Dr Chris Ojiewo of ICRISAT on “Seed systems supporting legume crop improvement.”
- Latest SeedWorld: Note in particular the article on QPM (quality protein maize) from CIMMYT (go to p 53).
- NordGen’s Write-up of the Farmers’ Pride conference “Ensuring Diversity for Food and Agriculture”: Note in particular Dr Maria Bönisch on the first official network for crop wild relatives in Europe.
- GRIN-U — Training resources for plant genetic resources conservation: Note in particular the genebank tours.
- The John Innes Centre genebank sends some wheat back to India. The Benin Bronzes next?
- Taewa, the Maori potato, gets a nice write-up. No word on returning it to somewhere in South America.
- Young researchers helping European farmers diversify. How about by using Indian wheat and Maori potatoes?
Brainfood: Food systems & biodiversity, Tree diversity, Cereal micronutrients, African crops in America, Coffee vulnerability, Coffee fungus, Wildrice, Wild coriander, Wild apple genebank, Laperrine’s olive, Maize landraces, Goat domestication, Honey bee cryo
- Biodiversity Towards Sustainable Food Systems: Four Arguments. For the record: food/nutrition security, climate change resilience, sustainable diets, resilience to zoonoses. I would have added something about culture.
- Biodiversity–productivity relationships are key to nature-based climate solutions. Greenhouse gas mitigation helps tree diversity helps productivity helps greenhouse gas mitigation.
- Genetic determinants of micronutrient traits in graminaceous crops to combat hidden hunger. Big crops can help little crops.
- Contributions of African Crops to American Culture and Beyond: The Slave Trade and Other Journeys of Resilient Peoples and Crops. Decolonizing American agriculture.
- Vulnerability of coffee (Coffea spp.) genetic resources in the United States. Americans have a cunning plan for an African crop.
- Historical genomics reveals the evolutionary mechanisms behind multiple outbreaks of the host-specific coffee wilt pathogen Fusarium xylarioides. Coffee Wilt Disease fungus got a boost from banana Panama Disease fungus. Got a plan for this?
- Improved Remote Sensing Methods to Detect Northern Wild Rice (Zizania palustris L.). They’re this close to putting in place an early warning system. Coffee next? But what about those micronutrients, eh?
- Wild coriander: an untapped genetic resource for future coriander breeding. Not only untapped, its very existence was in doubt. Detect this from space, Colin!
- Advanced genebank management of genetic resources of European wild apple, Malus sylvestris, using genome-wide SNP array data. The Dutch field collection can be managed as a single unit. Kind of a relief, probably. Coffee next?
- Contrasting Genetic Footprints among Saharan Olive Populations: Potential Causes and Conservation Implications. Looks like the wild Saharan olive cannot be managed as a single unit. Bet they can be monitored from space though.
- Growing maize landraces in industrialized countries: from the search for seeds to the emergence of new practices and values. Two contrasting approaches by farmers’ associations in France and Italy.
- Herded and hunted goat genomes from the dawn of domestication in the Zagros Mountains. Before goats were morphologically domesticated, they were managed and genetically domesticated. I wonder if coffee was the same.
- Europe’s First Gene Bank for Honey Bees. Really cold drone semen finds a home in Germany.
Brainfood: Insurance, Maize roots, Grass strips, Banana nutrients, Fish nutrients, Wild potatoes, Apple genes, Wheat resistance, Killer tomatoes
- Biodiversity as insurance: from concept to measurement and application. It’s important to draw a distinction between the effect of biodiversity on mean and on variance of ecosystem properties.
- Reproductive resilience but not root architecture underpins yield improvement under drought in maize (Zea mays L.). Which presents an opportunity.
- Functional traits driving pollinator and predator responses to newly established grassland strips in agricultural landscapes. Biodiversity takes its time.
- Genetic diversity in fresh fruit pulp mineral profile of 100 Indian Musa accessions. Plenty of diversity, though different micronutrients are correlated, and 100 g contributes only 5-10% of daily mineral requirements.
- Declining diversity of wild-caught species puts dietary nutrient supplies at risk. Let them eat bananas. More nuance.
- A Metric for Species Representation in the US Potato Genebank. Sort of like a core collection, but across species.
- Pyramiding resistance genes and widening the genetic base of the apple (Malus × domestica Borkh.) crop. From 36 cultivars, via 110 cross combinations, to 7,876 offsprings, to 2,969 after screening, to 75 genotypes each with 2-3 of the 20 Rvi6 genes. Hard row to hoe.
- Resistance to diseases in samples of rare wheat species from the N.I. Vavilov All-Russian Institute of Plant Genetic Resources. Very hard row to hoe. Septoria nodorum blotch seems to be particularly tricky.
- Alien introgression and morpho‑agronomic characterization of diploid progenies of Solanum lycopersicoides monosomic alien addition lines (MAALs) toward pre‑breeding applications in tomato (S. lycopersicum). I particularly like the bit where it bursts through John Hurt’s chest.
