- THP9 enhances seed protein content and nitrogen-use efficiency in maize. And it came from wild teosinte.
- Diverged subpopulations in tropical Urochloa (Brachiaria) forage species indicate a role for facultative apomixis and varying ploidy in their population structure and evolution. Polyploidy plus apomixis equals world domination. Maize next?
- Plastid phylogenomics uncovers multiple species in Medicago truncatula (Fabaceae) germplasm accessions. Genebanks need to go beyond conventional taxonomy sometimes.
- Comparative Analysis of the Genetic Diversity of Chilean Cultivated Potato Based on a Molecular Study of Authentic Herbarium Specimens and Present-Day Gene Bank Accessions. Native Chilean potato landraces are being replaced and polluted…

- Lactuca georgica Grossh. is a wild species belonging to the secondary lettuce gene pool: additional evidence, obtained by KASP genotyping. A wild species gets demoted.
- Large genomic introgression blocks of Phaseolus parvifolius Freytag bean into the common bean enhance the crossability between tepary and common beans. A wild species helps with crossing two cultivated species. Figure out which genepool it belongs to after that.
- Genebanking plant genetic resources in the postgenomic era. Yeah, but all the above leads to the question: “what happens when all crop diversity has been sequenced?” Read this to find out.
Brainfood: Silkworm, Donkey, Cat, Chicken, Neolithic, Shamans, Locusts
- High-resolution silkworm pan-genome provides genetic insights into artificial selection and ecological adaptation. The silkworm was domesticated 5000 years ago in the middle Yellow River (along with millets?), but was improved independently and in different directions in China and Japan.
- The genomic history and global expansion of domestic donkeys. The donkey was domesticated in the Horn of Africa 7000 years ago and then developed in different directions in Africa and Eurasia. Covered in the NY Times, no less.
- Your horse is a donkey! Identifying domesticated equids from Western Iberia using collagen fingerprinting. Turns out you can tell horses and donkeys apart easily and cheaply from ancient collagen in archaeological remains.
- Genetics of randomly bred cats support the cradle of cat domestication being in the Near East. Humans were domesticated by cats in the eastern Mediterranean basin about 12,000 years ago.
- The history of the domestic cat in Central Europe. Wait, the Near Eastern wildcat, from which all domestic cats are derived, could have been in central Europe before the Neolithic.
- Missing puzzle piece for the origins of domestic chickens. Recent dating of chicken domestication from archaeological remains in Thailand at 1650–1250 BC underestimates the timescale. By a lot.
- Was the Fishing Village of Lepenski Vir Built by Europe’s First Farmers? And did they have cats?
- Shamanism at the transition from foraging to farming in Southwest Asia: sacra, ritual, and performance at Neolithic WF16 (southern Jordan). You need shamans to help you cope with all that animal domestication.
- Contributions of black locust (Robinia pseudoacacia L.) to livelihoods of peri-urban dwellers in the Free State Province of South Africa. Wait, black locusts are not animals? Hmm, they do seem to have some things in common with cats though.
Brainfood: Coconut in vitro, Clean cryo, Chickpea & lentil collections, Genebank data history, Eurisco update, Mining genebank data, TIK, Sampling strategy, Drones, GIS, Mexican CWR, Post-2020 biodiversity framework
- Thiamine improves in vitro propagation of sweetpotato [Ipomoea batatas (L.) Lam.] – confirmed with a wide range of genotypes. Getting there, keep tweaking…
- Minimizing the deleterious effects of endophytes in plant shoot tip cryopreservation. Something else to tweak.
- Ex Situ Conservation of Plant Genetic Resources: An Overview of Chickpea (Cicer arietinum L.) and Lentil (Lens culinaris Medik.) Worldwide Collections. Thankfully not much in vitro and cryo involved. The main tweak necessary is to share more characterization data with breeders.
- Data, Duplication, and Decentralisation: Gene Bank Management in the 1980s and 1990s. Ah, but do calls for more data also reflect attempts to cut costs and build political bridges? And would that be so bad?
- EURISCO update 2023: the European Search Catalogue for Plant Genetic Resources, a pillar for documentation of genebank material. Arguably, Eurisco tries to do all of the above, and pretty well.
- Bioinformatic Extraction of Functional Genetic Diversity from Heterogeneous Germplasm Collections for Crop Improvement. You need fancy maths to make sense of all that data. And use it.
- Research Status and Trends of Agrobiodiversity and Traditional Knowledge Based on Bibliometric Analysis (1992–Mid-2022). Not much traditional knowledge in those databases, though, eh? That would be one hell of a tweak.
- Species-tailored sampling guidelines remain an efficient method to conserve genetic diversity ex situ: A study on threatened oaks. Meanwhile, some people are still trying to figure out the best way to tweak sampling strategies to add diversity to genebanks. Spoiler alert: you need data on individual species.
- Collecting critically endangered cliff plants using a drone-based sampling manipulator. You also need drones.
- Application of Geographical Information System for PGR Management. One thing you can do with all that data is map stuff. So at least the drones know where to go.
- Incorporating evolutionary and threat processes into crop wild relatives conservation. The only thing that’s missing from this is traditional knowledge. And maybe drones.
- Conserving species’ evolutionary potential and history: opportunities under the new post-2020 global biodiversity framework. All these data will allow us to measure how well we’re doing. And whether we can ask for cryotanks, drones, and better databases.
Brainfood: Indigenous crops, Indian vegetables, Local breeds, Wheat identity, Date names, Food security & heritage, Peruvian cuisine, Food sovereignty, Palestinian seeds, Tea culture, Sacred groves, Food system transformation, Diverse landscapes

- Because error has a price: A systematic review of the applications of DNA fingerprinting for crop varietal identification. Nobody’s perfect, even the colonially unbiased.
- What lies behind a fruit crop variety name? A case study of the barnī date palm from al-‘Ulā oasis, Saudi Arabia. Local variety names are complicated, no wonder mistakes happen.
- Food security and the cultural heritage missing link. Want to preserve cultural heritage AND boost productivity? Then support (1) preservation of genetic resources, (2) value addition, (3) traditional food processing, (4) preference matching, and (5) agritourism. What, no fighting colonial bias?
- Analysis of Innovation in Peru’s Gastronomic Industry. All of the above?
- Food sovereignty in sub-Saharan Africa: Reality, relevance, and practicality. All of the above are well and good, but not enough. You also need modern varieties. Just get their names right, eh?
- Baladi Seeds in the oPt: Populations as Objects of Preservation and Units of Analysis. Whatever you do, don’t reduce cultural heritage to data.
- Reinventing a Tradition: East Asian Tea Cultures in the Contemporary World. No danger of reducing tea to data, judging by this collection of papers.
- Factors driving the tree species richness in sacred groves in Indian subcontinent: a review. Not religion, apparently, according to the data. Go figure.
- The role of traditional knowledge and food biodiversity to transform modern food systems. There is plenty of evidence out there that bringing greater biodiversity into food systems results in multiple socio-cultural benefits. As this Brainfood, as well as the case studies in this paper, tries to show.
- Complex agricultural landscapes host more biodiversity than simple ones: A global meta-analysis. Had enough?

- Disentangling the Genetic Diversity of Grass Pea Germplasm Grown under Lowland and Highland Conditions. Always good to have multi-locational trial data, even when n=2.
- Hybridization, missing wild ancestors and the domestication of cultivated diploid bananas. Let the search for the 3 unknown wild ancestors begin!
- Improved pea reference genome and pan-genome highlight genomic features and evolutionary characteristics. If only Mendel had worked on wild peas too.
