- Seed in genebanks have fungi, and that could be a good thing.
- Seed sector mentions genebanks, and that’s a good thing.
- Seed libraries are great.
- You can take virtual tours of a couple of CGIAR genebanks, which can’t be bad.
Brainfood: Sweet cassava, Iranian wheat, Wild tomato, Ethiopian sorghum, Portuguese beans, Wild Algerian oats, Angolan Vigna, Apple tree, Regeneration, Robusta climate, Bronze Age diets, Maize domestication, Veld fruits, Red yeasts, Remote sensing
- Large‐scale genome‐wide association study, using historical data, identifies conserved genetic architecture of cyanogenic glucoside content in cassava (Manihot esculenta Crantz) root. Two loci explain about a third of variation in HCN content.
- Strategic use of Iranian bread wheat landrace accessions for genetic improvement: Core set formulation and validation. Not much structure, but some accessions are good for multiple traits.
- Population studies of the wild tomato species Solanum chilense reveal geographically structured major gene-mediated pathogen resistance. Not all populations of a crop wild relatives will be equally useful in breeding.
- Genetic diversity of Ethiopian sorghum reveals signatures of climatic adaptation. 12 sub-populations, with about 10% of the variation explained by either agroecology or geography.
- Common bean SNP alleles and candidate genes affecting photosynthesis under contrasting water regimes. And all in just 158 Portuguese accessions.
- Genetic Diversity and Population Structure of Algerian Endemic Plant Species Avena macrostachya Bal. ex Cross. et Durieu. Collecting sites need to be visited again. I can vouch that doing so would be very interesting.
- Conservation priorities for African Vigna species: Unveiling Angola’s diversity hotspots. It’s a huge collecting gap.
- Remote sensing enabled essential biodiversity variables for biodiversity assessment and monitoring: technological advancement and potentials. The Remote Sensing enabled Essential Biodiversity Variables are a work in progress. Would like to see it applied to those Vignas.
- Genomic consequences of apple improvement. …are relative genetic uniformity.
- Genome-Wide DArTSeq Genotyping and Phenotypic Based Assessment of Within and Among Accessions Diversity and Effective Sample Size in the Diverse Sorghum, Pearl Millet, and Pigeonpea Landraces. Optimal sample size for regeneration of genebank accessions varies from 50-200 among crops.
- Not so robust: Robusta coffee production is highly sensitive to temperature. Looking at historical production data from 800 farms in SE Asia suggests optimal temperature is below 20°C, a lot lower than suggested by the species’ home range in the Congo Basin.
- Exotic foods reveal contact between South Asia and the Near East during the second millennium BCE. Bronze Age Levantines ate bananas and soya, according to dental calculus. No word on coffee.
- Archaeological Central American maize genomes suggest ancient gene flow from South America. Pre-domesticated maize was taken to South America, where is was finished off away from introgression from pesky wild relatives, and then taken back home.
- Fruits of the Veld: Ecological and Socioeconomic Patterns of Natural Resource Use across South Africa. South Africans collect and eat a lot of wild fruits, but could plant and eat them more.
- Exploring the Biodiversity of Red Yeasts for In Vitro and In Vivo Phenotypes Relevant to Agri-Food-Related Processes. Which is interesting because they can delay food spoilage and also provide nutritional supplements. Though personally I’d prefer veld fruits.
Nibbles: Macron magic, UK Strategic Priorities Fund, Macadamia, Tepary, Nordic spuds, Diversification, Carolina rice, Couscous, Wild tobacco, Yeast diversity, Da 5 Foods
- France pushes for agricultural development. Money to follow mouth?
- Meanwhile, Britain puts its money into its own food systems.
- The macadamia is not diverse enough. Who’d have thought it.
- Couscous gets protected. Phew, ’cause it’s right on the verge of extinction, isn’t it.
- I hope tepary beans don’t become the next macadamia.
- Reviving old potatoes the Nordic way.
- Malaysia told to look beyond oil palm. To tepary and macadamia, maybe?
- Speaking of diversification, how about Laotian rice in Appalachia?
- Chasing the wild tobacco. See what I did there?
- Yeast has been domesticated by bakers into two genetic groups: industrial and artisanal sourdough.
- A history of the world in entirely the wrong 5 foods.
Nibbles: Benchmarking, Unintended consequences, Kenyan seeds, WFP, China genebank, Evolutionary plant breeding, Citrus, Maize, Lotus silk, Azolla, Spanish genebank
- How committed are 350 food companies to food system transformation? Well, take a wild guess…
- Mind you, transformation is tricky.
- A climate-smart seed system for Kenya? Would be transformative for sure.
- Great that WFP got the Nobel Peace Prize, but they’re only part of the food system picture.
- Another part is genebanks, as China recognizes.
- One way to use all that material in genebanks is through evolutionary plant breeding.
- Citrus: How it started. How it’s going. Meme alert.
- Maize was taken back to Mexico from South America in ancient times. And those early farmers really knew how to process it for maximum benefit, something we’re forgetting.
- A deep dive into lotus silk.
- An even deeper dive into Azolla-covered paddies.
- Esteban Hernández of the Andalusian genebank gets his 15 minutes.
Brainfood: Topical forages, Ne, Pearl millet nutrition, Sorghum strategy, Tillering rice, Exchanging wheat, Recollecting wheat, Yeast domestication, Amazonian maize, Synthesizing groundnut, Strawberry dispersal, Soya structure, Remote change, Green Revolution, Unintended consequences
- Tropical forage technologies can deliver multiple benefits in Sub-Saharan Africa. A meta-analysis. Including improved germplasm, which had on average 2.6 times higher herbage productivity than local controls.
- Effective population size remains a suitable, pragmatic indicator of genetic diversity for all species, including forest trees. Which is good because you can estimate it fairly easily. Well, kinda. It’s important because it’s one of the Genetic diversity targets and indicators proposed for the CBD post-2020 Global Biodiversity Framework.
- Exploring the genetic variability and diversity of pearl millet core collection germplasm for grain nutritional traits improvement. 15 of 212 accessions are good for multiple nutrients.
- Global Status of Sorghum Genetic Resources Conservation. The two biggest collections are updating their data.
- Genomic basis of geographical adaptation to soil nitrogen in rice. Rice lost high tillering in high N conditions, but can get it back to cope with low N conditions.
- The Economic Impact of Exchanging Breeding Material: Assessing Winter Wheat Production in Germany. It really pays for breeders to exchange material.
- Comparative analysis of the gene pool structure of Triticum aethiopicum wheat accessions conserved ex situ and recollected in fields after 85 years. Vavilov’s collections are more diverse.
- Evidence for Two Main Domestication Trajectories in Saccharomyces cerevisiae Linked to Distinct Bread-Making Processes. Being adapted for industrial and artisanal baking respectively.
- Entrelaçado, a rare maize race conserved in Southwestern Amazonia. Gap-filling pays off. Hope we can re-collect it in 85 years’ time.
- ValSten: a new wild species derived allotetraploid for increasing genetic diversity of the peanut crop (Arachis hypogaea L.). Playing God with peanuts.
- Long-distance dispersal of the beach strawberry, Fragaria chiloensis, from North America to Chile and Hawaii. For the birds.
- Genetic architecture of wild soybean (Glycine soja Sieb. and Zucc.) populations originating from different East Asian regions. At least 3 separate groups, and the collection stored in Korea is pretty representative.
- Supporting habitat conservation with automated change detection in Google Earth Engine. Fancy math can detect land use change quickly and accurately.
- Health Impacts of the Green Revolution: Evidence from 600,000 births across the Developing World. Modern varieties reduced infant mortality by 2.4–5.3 percentage points (from 18%), with stronger effects for male infants and among poor households. Why we do all of the above?
- Articulating the effect of food systems innovation on the Sustainable Development Goals. Yeah, not so fast…
