- Global spatially explicit yield gap time trends reveal regions at risk of future crop yield stagnation. For 8 of 10 major crops, yield gaps have widened steadily from 1975 to 2010 over most areas, and remained static for sugar cane and oil palm. Time to turbo-charge the breeding?
- Domestication and the evolution of crops: variable syndromes, complex genetic architectures, and ecological entanglements. If you want to turbo-charge breeding, you need to understand (among other things) the ecological context of domestication.
- Including Traditional Ecological Knowledge (TEK) in Agricultural Research: Guidelines and Lessons Learned. I suspect Traditional Ecological Knowledge can help with figuring out the ecological context of domestication.
- High levels of genetic variation and differentiation in wild tropical gourds provide a novel resource for cucurbit crop improvement. Ok, but ecological knowledge would like a word.
- Understanding genetic diversity in drought-adaptive hybrid parental lines in pearl millet. Any link to ecology of original collecting sites, I wonder?
- Genetic Diversity and Population Structure Analysis of a Diverse Panel of Pea (Pisum sativum). Again, ecological knowledge conspicuous by its absence. Maybe the passport data just weren’t up to it?
- Banana seed exchange networks in Burundi – Linking formal and informal systems. Yes, yes, it’s not just about the breeding, the seed system also has to work.
- Editorial: Current status of honey bee genetic and breeding programs: progress and perspectives. Pollinators need breeding programmes too.
Nibbles: VACS, FAO forgotten foods, African roots, Hopi corn, Adivasis rice, Sustainable farming, Llama history, Vicuña sweaters, Portuguese cattle, Mexico genebank, NZ genebank, Bat pollination, Eat This Newsletter, WEF
- More on the US push for opportunity crops.
- Oh look there’s a whole compendium on African opportunity crops from FAO.
- Many of them are roots and tubers.
- For the Hopi, maize is an opportunity crop.
- For the Adivasis, it’s rice.
- And more along the same lines from Odisha.
- Llamas were an opportunity for lots of people down the ages.
- …and still are, for some.
- Portugal eschews llamas for an ancient cattle breed.
- I bet Mexico’s genebank offers some amazing opportunities.
- And New Zealand’s too.
- Let’s not forget bats. Yes, bats.
- Jeremy’s latest newsletter tackles turmeric, pepper and sweet potatoes, among other things.
- And the best way to frame all of the above is that the World Economic Forum wants governments to ban people from growing their own food because that causes climate change.

- Frugivory by carnivores: Black-backed jackals are key dispersers of seeds of the scented !nara melon in the Namib Desert. Jackals pee on wild melon relatives and disperse their seeds, not necessarily in that order.
- Out of the Shadows: Reestablishing the Eastern Fertile Crescent as a Center of Agricultural Origins: Part 1. Go East, young archaeobotanists!
- Extinction risk predictions for the world’s flowering plants to support their conservation. Fancy maths says 45% of angiosperms are potentially threatened. Same for crop wild relatives in the Eastern Fertile Crescent? Black-backed jackals unavailable for comment.
- Global Wild Rice Germplasm Resources Conservation Alliance: WORLD WILD-RICE WIRING. Scientists get together to conserve global wild rice germplasm resources, understand the ecology of wild rice environments, identify and address threats, define effective ways to use wild species in rice improvement, and provide data for decision-making. Not a minute too soon, given the above.
- Morphometric analysis of wild potato leaves. Who needs genotyping anyway.
- Large-scale gene expression alterations introduced by structural variation drive morphotype diversification in Brassica oleracea. Brassica scientists need genotyping, apparently, that’s who.
- Exploring the nutritional potentials of wild Vigna legume species for neo-domestication prospects. Not much potential if they go extinct though. Quick, photograph their leaves!
Brainfood: Archaeology edition
- Early human selection of crops’ wild progenitors explains the acquisitive physiology of modern cultivars. The high leaf nitrogen, photosynthesis, conductance and transpiration of crops was already there in their wild relatives, the first farmers just happened to domesticate greedy plants.
- The impact of farming on prehistoric culinary practices throughout Northern Europe. When the first farmers arrived in northern Europe armed with their greedy plants, they learned a lot about food from the local hunter-fisher-gatherers, and vice-versa, but without much interbreeding. Jeremy interviews one of the authors on his podcast.
- Early contact between late farming and pastoralist societies in southeastern Europe. There was extensive interbreeding between farmers and the local transitional foragers/herders before with the expansion of pastoralist groups into Europe from the Eurasian steppes around 3300 BC.
- Isotopes prove advanced, integral crop production, and stockbreeding strategies nourished Trypillia mega-populations. The earliest European mega-settlements, in Ukraine and Moldova, from around 4000 BCE, integrated greedy crops and generous domesticated livestock.
- Inference of Admixture Origins in Indigenous African Cattle. Following introduction from the Near East, domesticated cattle got admixed with a North African extinct aurochs before spreading throughout Africa.
- Flax for seed or fibre use? Flax capsules from ancient Egyptian sites (3rd millennium BC to second century AD) compared with modern flax genebank accessions. Fibre first.
- Revealing the secrets of a 2900-year-old clay brick, discovering a time capsule of ancient DNA. DNA from 34 plant groups were detected inside an old brick when it happened to break.
- Making wine in earthenware vessels: a comparative approach to Roman vinification. Comparison with modern counterparts shows that Roman clay jars for storing wine were integral to the process. No word on whether there was any ancient DNA in the clay.
- Breadfruit in the Pacific Islands, its domestication and origins of cultivars grown in East Polynesia and Micronesia. Spoiler alert: they came from Polynesian Outlier Islands.
Brainfood: Breeding edition
- Climate-resilient crops: Lessons from xerophytes. Breeding for Na+ exclusion to improve salinity tolerance in crops has compromised their drought tolerance, but both tolerances are down to more gene copies in key families when comparing species.
- Innovation and Technological Mismatch: Experimental Evidence from Improved Crop Seeds. Breeders should strive to give farmers what they want, even if it means releasing multiple locally adapted varieties rather than a single blockbuster.
- Stressors and Resilience within the Cassava Value Chain in Nigeria: Preferred Cassava Variety Traits and Response Strategies of Men and Women to Inform Breeding. Man and women want different things from cassava breeders.
- Intra-household discrete choice experiment for trait preferences: a new method. If only there was a new way to measure that…
- Genome editing to re-domesticate and accelerate use of barley crop wild relatives. No word on whether men and women would edit different genes.
- Understanding Genome Structure Facilitates the Use of Wild Lentil Germplasm for Breeding: A Case Study with Shattering Loci. I suspect neither men nor women would tolerate shattering lentils.
- Repeat turnover meets stable chromosomes: repetitive DNA sequences mark speciation and gene pool boundaries in sugar beet and wild beets. But you can’t use wild species in breeding if you can’t cross them with the crop, and in beet that’s down to the repeatome. So maybe this would make a better case for domestication through gene editing than barley or lentils?
- Development of trait-specific genetic stocks derived from wild Cicer species as novel sources of resistance to important diseases for chickpea improvement. Would be really cool to domesticate one of the really resistant tertiary genepool species.
- Developing Genetic Resources Within the Chenopodium Genus to Advance Quinoa Breeding and the de novo Domestication of C. berlandieri. Not that you need gene editing for domesticating crop wild relatives.
- Genomic traces of Japanese malting barley breeding in two modern high-quality cultivars, ‘Sukai Golden’ and ‘Sachiho Golden’. Old-fashioned breeding has been pretty successful, so who needs CWR, gene editing and discrete choice experiments? ((Last bit added purely for clicks, I’m desperate.))
- Consistent effects of independent domestication events on the plant microbiota. I hope all those gene-editing de novo domesticators are considering the novo microbiomes.
