- Enhancing the functioning of farm animal gene banks in Europe: results of the IMAGE project. Lots going on, but avian species in particular need more work.
- Conservation and Utilization of Livestock Genetic Diversity in the United States of America through Gene Banking. Over 1,000,000 samples from over 55,000 animals, representing 165 livestock and poultry breeds, collected over 60 years, more than 50% of rare breeds.
- Cryoconservation of Animal Genetic Resources in Europe and Two African Countries: A Gap Analysis. Out of the 2949 breeds registered in DAD-IS, 16% have material in genebanks, but only 4% have enough to allow breed reconstitution.
- Unlocking the origins and biology of domestic animals using ancient DNA and paleogenomics. How we got to the above.
- Distributions, conservation status, and abiotic stress tolerance potential of wild cucurbits (Cucurbita L.). 13 out of 16 taxa need in situ and ex situ work.
- Wild potato Genetic Reserves in Protected Areas: prospection notes from Los Cardones National Park, Salta, Argentina. Nice combination of in situ and ex situ.
- Agricultural intensification was associated with crop diversification in India (1947-2014). But only at country level, and not by much. At district level, crop diversity went down in rice/wheat areas and up in the south and west as oilseeds and vegetables replaced millet and sorghum. Doesn’t strike me as positive overall, diversity-wise.
- From population to production: 50 years of scientific literature on how to feed the world. Time for a bit of holism.
- Unlocking the Genetic Diversity and Population Structure of a Wild Gene Source of Wheat, Aegilops biuncialis Vis., and Its Relationship With the Heading Time. 5 ecogeographic clusters, 4 related heading time groups.
- Genomic Evidence for Complex Domestication History of the Cultivated Tomato in Latin America. Domestication of northerly migrating wildish material in Mexico rather than 2-step domestication in S America and then Mexico.
- Enset‐based agricultural systems in Ethiopia: A systematic review of production trends, agronomy, processing and the wider food security applications of a neglected banana relative. Better data needed, for a start.
- Worldwide Genetic Resources of Duckweed: Stock Collections. 36 species, no less. Need more?
- Realizing hybrids between the cultivated peanut (Arachis hypogaea L.) and its distantly related wild species using in situ embryo rescue technique. You need to apply growth substances to the pollinated flowers.
- The remarkable morphological diversity of leaf shape in sweet potato (Ipomoea batatas): the influence of genetics, environment, and G×E. Genetics controls shape, environment size.
- Adaptation and development pathways for different types of farmers. Watch your context, and don’t forget governance.
- Golden Rice and technology adoption theory: A study of seed choice dynamics among rice growers in the Philippines. They forgot context. And governance. But let the author spell it out in a tweet thread.
Soil biodiversity assessments around the world
Alberto Orgiazzi, who a few months ago summarized global soil biodiversity mapping in a tweet, has done it again:

Time to join efforts indeed.
Brainfood: Potato genebanks, Aichi 11, Taming foxes, Fruit diversity, Polyploidy review, Evaluating quinoa, Into Africa, IPCC review, Desiccation tolerance, Pig diversity, Oolong diversity, Wild millet, Sustainable diets
- Ex Situ Conservation of Potato [Solanum Section Petota (Solanaceae)] Genetic Resources in Genebanks. The only review of the subject you’ll need. Until the next one.
- Editorial Essay: An update on progress towards Aichi Biodiversity Target 11. Not bad, but the difficult stuff remains difficult. One of several interesting papers.
- The History of Farm Foxes Undermines the Animal Domestication Syndrome. Those Russian foxes were already pretty tame. Here’s a Twitter tread from one of the authors that lays it all out.
- Developing fruit tree portfolios that link agriculture more effectively with nutrition and health: a new approach for providing year-round micronutrients to smallholder farmers. 11 species can address micronutrient gaps.
- Plant Polyploidy: Origin, Evolution, and Its Influence on Crop Domestication. Extreme events and disasters drive polyploidy, which drives diversification at various levels, which facilitates domestication.
- Spectral Reflectance Indices and Physiological Parameters in Quinoa under Contrasting Irrigation Regimes. Phenotyping for drought tolerance from space.
- Asian Crop Dispersal in Africa and Late Holocene Human Adaptation to Tropical Environments. Via NE Africa always something new.
- Invited review: Intergovernmental Panel on Climate Change, agriculture, and food — A case of shifting cultivation and history. The IPCC could have done a better job of synthesizing the data on the impact of climate change on crops and livestock.
- Seed comparative genomics in three coffee species identify desiccation tolerance mechanisms in intermediate seeds. Whole bunch of genes involved.
- Capturing genetic diversity – an assessment of the nation’s gene bank in securing Duroc pigs. Genebank doing a pretty good job in this case.
- Genetic diversity of oolong tea (Camellia sinensis) germplasms based on the nanofluidic array of single-nucleotide polymorphism (SNP) markers. It’s not all the same.
- Tapping Pennisetum violaceum, a wild relative of pearl millet (Pennisetum glaucum), for resistance to blast (caused by Magnaporthe grisea) and rust (caused by Puccinia substriata var. indica). Out of 305 accessions, one was resistant to both diseases. IP21711 if you must know. A few more were resistant to one or the other disease.
- Can Diets Be Healthy, Sustainable, and Equitable? No, and they’ll be difficult to change, but the “burden of change should not be solely placed on the consumer’s ability to make healthy choices.”
Culture, Agriculture, Food & Environment, and genebanks
Dr Helen Anne Curry, Peter Lipton Lecturer in History of Modern Science and Technology at the University of Cambridge, guest edited a special issue on “The Collection and Conservation of Plant Genetic Resources” for the journal Culture, Agriculture, Food & Environment in December.
Looks good. A couple of the papers are even open access. I admit I haven’t read them yet, but I will, and report back.
And watch out for Dr Curry’s new project “From Collection to Cultivation: Historical Perspectives on Crop Diversity and Food Security,” which is launching this year with support from a Wellcome Trust Investigator Award.
