- Might consumers care about genetics?
- Well they do, right? At least if they’re into heirloom varieties and heritage breeds.

Brainfood: Bending the curve edition
- Bending the curve of terrestrial biodiversity needs an integrated strategy. Meaning: (i) sustainable agricultural intensification, (ii) trade, (iii) less food waste, (iv) more plant-based human diets, and (v) more and better protected areas.
- The carbon opportunity cost of animal-sourced food production on land. See (iv) above.
- Just ten percent of the global terrestrial protected area network is structurally connected via intact land. See (v) above.
- Cropland expansion in the United States produces marginal yields at high costs to wildlife. See (i) above.
- A cultivated planet in 2010 – Part 1: The global synergy cropland map. Gotta know where the cropland is before you can do (i) above.
- Advances in plant phenomics: From data and algorithms to biological insights. Fancy maths can really help with (i) above.
- Retrospective Quantitative Genetic Analysis and Genomic Prediction of Global Wheat Yields. Different fancy maths shows that CIMMYT’s Obregon wheat testing site can really help with (i) above.
- Diversity analysis of 80,000 wheat accessions reveals consequences and opportunities of selection footprints. Here’s some stuff that wheat breeders can use to develop new materials to test at Obregon using phenomics, genomics and fancy maths.
- First report on cryopreservation of mature shoot tips of two avocado (Persea americana Mill.) rootstocks. This should help with (iv) above. Eventually, work with me here.
- Bread and porridge at Early Neolithic Göbekli Tepe: A new method to recognize products of cereal processing using quantitative functional analyses on grinding stones. Ahem. Well… No, sorry, I got nothing.
Brainfood: CGIAR, Genebank data, AI & diseases, Mentha CWR, Tree crops, Carrot diversity, Rice sampling, Perennial rice, Rice de-domestication, Malagasy deforestation, Saving pollinators, Sheep domestication, FFS, Wine signatures
- The development of the international center model for agricultural research: A prehistory of the CGIAR. The model didn’t start with those canonical US foundations, and owes more than a little to colonialism. Further integration is needed.
- Document or Lose It—On the Importance of Information Management for Genetic Resources Conservation in Genebanks. Standardization, openness and interoperability. Easier said than done, but if you’re looking for further integration…
- AI-powered banana diseases and pest detection. But can it tell bananas from plantains? Nice to link it up with the above.
- Crop Wild Relatives as Germplasm Resource for Cultivar Improvement in Mint (Mentha L.). 450 clones representing 34 taxa maintained by USDA. The next 2 are USDA things too.
- Germplasm Development of Underutilized Temperate U.S. Tree Crops. Sure, introduce species from abroad, but if they have local wild relatives you have another route to adaptation. Take the hazelnut, for example…
- Subspecies Variation of Daucus carota Coastal (“Gummifer”) Morphotypes (Apiaceae) Using Genotyping-by-Sequencing. One morphology and niche, 5 genetic groups.
- Comparisons of sampling methods for assessing intra- and inter-accession genetic diversity in three rice species using genotyping by sequencing. Some differences in results among sampling methods, but not huge.
- Combining ability analysis on rhizomatousness via incomplete diallel crosses between perennial wild relative of rice and Asian cultivated rice. If you want perennial cultivated(ish) rice, you have to pick your parents carefully.
- Something old, something new: Evolution of Colombian weedy rice (Oryza spp.) through de novo de‐domestication, exotic gene flow, and hybridization. Weedy rice is just local domesticated rice gone bad, at least in Colombia. Gosh I hope that perennial rice doesn’t get de-domesticated.
- It’s not just poverty: unregulated global market and bad governance explain unceasing deforestation in Western Madagascar. Stop blaming subsistence slash-and-burn.
- Climate change enforces to look beyond the plant – the example of pollinators. Create nice conditions for pollinators on farms, it’ll be worth it.
- Paternal Origins and Migratory Episodes of Domestic Sheep. 4 parental lineages, one with primitive features and another with fat tails.
- Women and Fish-for-Sex: Transactional Sex, HIV/AIDS and Gender in African Fisheries. Teach a man to fish, FFS.
- Use of Untargeted Liquid Chromatography–Mass Spectrometry Metabolome To Discriminate Italian Monovarietal Red Wines, Produced in Their Different Terroirs. A little wine with your fish? Ah no, wait, these are all reds. But at least you can tell them apart now.
Welcome to the world, Kurt
What can you do about inbreeding in a small population of a species that nearly went extinct? Well, if the species is Przewalski’s horse, one thing you can do is inject some new diversity into the genepool by cloning a genetically very distinct stallion whose cells you happened to put in liquid nitrogen forty years ago. The whole amazing story is on the website of the Revive & Restore project.
This is huge. The first cloning for conservation.
It's a male Przewalski's horse ("shuh-VAL-ski") from 40 years ago, now revived to help enrich the genomes of the whole wild population.

The new foal’s name is Kurt. Why?
Kurt is named in honor of Dr. Kurt Benirshke, a geneticist at the San Diego Zoo who in 1975 had a prescient idea. Dr. Benirshke began what is now the Frozen Zoo, collecting and cryopreserving the cell lines of endangered species and safely storing away genetic diversity before it was lost. At the time the collection was a bet on cloning and reproductive technologies that did not yet exist. Nearly fifty years later, with the partnership of San Diego Zoo Global Frozen Zoo, Revive & Restore, and ViaGen Pets and Equine, Dr. Benirschke’s plans are quite literally coming to life.
