- Palaeogenomics of Upper Palaeolithic to Neolithic European hunter-gatherers. Farmers may have pushed hunter-gatherers to the northern edge of Europe while also in mixing with them.
- Identification and exploitation of wild rye (Secale spp.) during the early Neolithic in the Middle Euphrates valley. Those Europeans on the move — both farmers and hunter-gatherers — would have been familiar with wild rye, but that’s pretty much gone from the Fertile Crescent now.
- Caribbean Deep-Time Culinary Worlds Revealed by Ancient Food Starches: Beyond the Dominant Narratives. But enough about Europe. It wasn’t always all about cassava in the pre-colonial, and indeed colonial, Caribbean…
- Reuniting the Three Sisters: collaborative science with Native growers to improve soil and community health. …as there was also the maize/beans/squash system in that part of the world, and may well be again.
- Understanding Early Modern Beer: An Interdisciplinary Case-Study. Something else that could come back is early modern Irish beer, and I’d be there for that.
- Forgotten forest relics: Apple trees (Malus spp.) in eastern U.S. forests. Old abandoned orchards, and escapes therefrom, could have lots of interesting apple diversity. Early modern American cider, anyone?

- Resynthesized Rapeseed (Brassica napus): Breeding and Genomics. Sure, we can rebuild it, we have the technology. But will it go feral on us again?
Nibbles: ICRISAT breeding, India climate change, Seed catalogues, Karabakh horse
- New ICRISAT varieties of sorghum, pearl millet and pigeonpea are doing well in drought-hit Kenya. For now, at least: something to keep an eye on. Genebanks and breeding to the rescue?
- It’s behind a Times of India paywall, alas, but this seems to be an article about the effects of a very warm February on wheat, vegetables and grapes in that country.
- Spring is coming to the northern hemisphere, so of course The New Yorker has a piece on the allure of seed catalogues. I hope there are drought-tolerant and heat-resistant varieties in there. And that they’re clearly labelled as such.
- Meanwhile, oblivious of it all, AramcoWorld has an elegiac piece on the revival of the Karabakh horse in Azerbaijan. Beautiful plumage.
Brainfood: Genomics for conservation and use edition
- How genomics can help biodiversity conservation. Let’s find out, but let’s broaden it to use as well, shall we? On the assumption that what’s good for conservation is good for use, and vice versa.
- Genetic and genomic interventions in crop biofortification: Examples in millets. Genomics can help you get more nutritious millets, and also use millets to improve the nutritive content of other cereals too.
- Genomics and biochemical analyses reveal a metabolon key to β-L-ODAP biosynthesis in Lathyrus sativus. Genomics can help you figure out ways to decrease the toxicity of grasspea.

- Balancing grain yield trade-offs in ‘Miracle-Wheat’. Genomics can help you figure out the best phenotype in wheat.
- Focusing the GWAS Lens on days to flower using latent variable phenotypes derived from global multienvironment trials. Genomics can help you figure out the best phenotype in lentils too.
- Awned versus awnless wheat spikes: does it matter? Although actually you don’t necessarily need genomics to help you figure out the best phenotype in wheat. But let’s get back on track.
- SNP Diversity and Genetic Structure of “Rogosija”, an Old Western Balkan Durum Wheat Collection. That’s better. Genomics can help you figure out that a wheat collection can consist of distinct ecogeographic groupings.
- Repeatability of adaptation in sunflowers: genomic regions harbouring inversions also drive adaptation in species lacking an inversion. Genomics can help you figure out what’s behind local adaptation in crop wild relatives.
- Re-evaluating Homoploid Reticulate Evolution in Helianthus Sunflowers. Genomics can help you figure out the evolutionary history of crop wild relatives. Where have I heard that before?
- A thousand-genome panel retraces the global spread and adaptation of a major fungal crop pathogen. Genomics can help you figure out the evolutionary history of plant pathogens too. Here’s a Twitter thread from one of the authors with lots of maps to prove it.
- Honey bee populations of the USA display restrictions in their mtDNA haplotype diversity. Yeah, you guessed it, pollinators too.
- Mezcal worm in a bottle: DNA evidence suggests a single moth species. I rest my case.
Nibbles: Green seeds, Yam bean, Aussie wild tomato, Einkorn trial, US sorghum, Ethiopian forages tricot, Cuisine diversity, Apple catalogue, Hittite crash, Black Death
- Let’s say we wanted to transition to a more local and low-input production system in Europe. What seeds would we need and where would we get them from? The Greens/EFA in the European Parliament have some ideas.
- IITA is pushing the yam bean in Nigeria. Europe next?
- More on that new Australian wild tomato from a couple of years back. With audio goodness.
- The largest ever einkorn variety comparison trial makes the German news. Well, makes a press release anyway. Yam bean next?
- Another continent, another ancient grain: sorghum in the US. Yam bean next?
- The Ethiopia Grass project aims to improve livestock production, food crop yields AND soil quality. The trifecta!
- Nice infographics displaying dodgy data on the most common ingredients in different cuisines. Yam bean and einkorn nowhere to be seen.
- Cool community-created online catalogue of British apples. Looking forward to the yam bean one.
- It was drought that did for the Hittites, not lack of yam beans. Sea Peoples unavailable for comment.
- It was Yersinia pestis from Issyk-Kul that nearly did for Europe in the Middle Ages. Yes, you can study the genetic diversity of ancient deadly bugs and well as that of crops like yam bean and einkorn.
Brainfood: Zea, Urochloa, Medicago, Solanum, Juglans, Camellia, Artocarpus, Lactuca, Phaseolus, and everything else
- Genome sequencing reveals evidence of adaptive variation in the genus Zea. Alleles associated with flowering time were key to adaptation in highland and temperate regions.
- 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.

- Diversity of Late Blight Resistance Genes in the VIR Potato Collection. …and will probably continue to be replaced and polluted.
- The United States Potato Genebank Holding of cv. Desiree is a Somatic Mutant of cv. Urgenta. Shit happens, even in well-run genebanks.
- Domestication and selection footprints in Persian walnuts (Juglans regia). Breeding hasn’t had much of an effect on diversity.
- Comparative phylogenetic analysis of oolong tea (Phoenix Dancong tea) using complete chloroplast genome sequences. Oolong teas are a genetic thing.

- 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.
