- A New Methodological Approach to Detect Microcenters and Regions of Maize Genetic Diversity in Different Areas of Lowland South America. Multiple disciplines identify 4 microcenters of maize diversity in the lowlands of South America.
- Historical Routes for Diversification of Domesticated Chickpea Inferred from Landrace Genomics. Genomics identifies both Indian and Middle Eastern traces in Ethiopian chickpeas.
- Crop wild relatives in Lebanon: mapping the distribution of Poaceae and Fabaceae priority taxa for conservation planning. Spatial analysis identifies a couple of key ex situ and in situ conservation areas for CWR in Lebanon.
- Analysis of gaps in rapeseed (Brassica napus L.) collections in European genebanks. Spatial analysis identifies a few key ex situ and in situ conservation areas for rapeseed wild relatives in Europe.
- Genomic and population characterization of a diversity panel of dwarf and tall coconut accessions from the International Coconut Genebank for Latin America and Caribbean. Characterization of various sorts identifies different Atlantic and Pacific coconut genepools in the Western Hemisphere.
- Pleistocene-dated genomic divergence of avocado trees supports cryptic diversity in the Colombian germplasm. Genomics identifies a uniquely Colombian avocado genepool.
- Analysis of >3400 worldwide eggplant accessions reveals two independent domestication events and multiple migration-diversification routes. Genomics identifies separate Southeast Asia and Indian areas of domestication, and limited exchange between them.
- Population genomics identifies genetic signatures of carrot domestication and improvement and uncovers the origin of high-carotenoid orange carrots. Genomics identifies wester-central Asia as the area of carrot domestication in the Early Middle Ages, and western Europe as the place where the orange variant was selected in the Renaissance.
- A Citrullus genus super-pangenome reveals extensive variations in wild and cultivated watermelons and sheds light on watermelon evolution and domestication. Pangenomics identifies a gene in wild Kordofan melons as promoting the accumulation of sugar in watermelon.
- Pangenome analysis provides insight into the evolution of the orange subfamily and a key gene for citric acid accumulation in citrus fruits. Pangenomics identifies south central China as the primary centre of origin of the genus Citrus.
- Pangenome analyses reveal impact of transposable elements and ploidy on the evolution of potato species. Pangenomics identifies wild species from North and Central America as having lots of genes for abiotic stress response, but also fewer transposable elements.
- Pangenomic analysis identifies structural variation associated with heat tolerance in pearl millet. Pangenomics identifies the key genes and structural variations associated with pearl millet accessions from the most hot and dry places.
- Dark side of the honeymoon: reconstructing the Asian x European rose breeding history through the lens of genomics. Genomics and other data identifies a shift from a European to a mainly Asian genetic background in cultivated roses during the 19th century, leading to a narrowing of genetic diversity.

- Salt-Tolerant Crops: Time to Deliver. Sure, breeding for salt tolerance using crop wild relatives is great, but have you tried just domesticating salt-tolerant wild species?
- Wild and cultivated comestible plant species in the Gulf of Mexico: phylogenetic patterns and convergence of type of use. No word on how many are salt-tolerant.
- Underutilized plants increase biodiversity, improve food and nutrition security, reduce malnutrition, and enhance human health and well-being. Let’s put them back on the plate! No word on how many are salt-tolerant.
- Indigenous crop diversity maintained despite the introduction of major global crops in an African centre of agrobiodiversity. If you want local crop diversity in Highland Ethiopia, look for it on the farms of the poorest. No word on how many are “underutilized”.
- The role of minor cereals in food and nutrition security in Bangladesh: constraints to sustainable production. Low yields, apparently. I think it could do with having aromatic grains. If only there was a way to make that happen…
- De novo creation of popcorn-like fragrant foxtail millet. Yeah, sometimes neither the crop not its wild relatives has the genes for it. Still, if you can edit in aroma, why not salt-tolerance?
- Global Genepool Conservation and Use Strategy for Dioscorea (Yam). I wonder how many of these 27 wild species could usefully be domesticated. Or are salt-tolerant.
- Towards conservation and sustainable use of an indigenous crop: A large partnership network enabled the genetic diversity assessment of 1539 fonio (Digitaria exilis) accessions. This is how you start to undo underutilization. I’m sure someone will edit it next.
- Diversity Assessment of Winged Bean [Psophocarpus tetragonolobus (L.) DC.] Accessions from IITA Genebank. Same as above, but with one hundredth as many accessions. I guess winged bean is even more underutilized than fonio.
- The forgotten giant of the Pacific: a review on giant taro (Alocasia macrorrhizos (L.) G.Don). Sad to say it doesn’t seem to be salt-tolerant. Maybe it’s aromatic, though. Or could be gene-edited to become so. Wouldn’t that be something.
- Retracing the center of origin and evolutionary history of nutmeg Myristica fragrans, an emblematic spice tree species. No need for editing, let’s just conserve the really diverse populations of the North Moluccas.
- Demographic history and distinct selection signatures of two domestication genes in mungbean. Domesticating the mungbean wasn’t all that easy. Hope it’s easier for some random salt-tolerant wild species.
- A plausible screening approach for moisture stress tolerance in finger millet (Eleusine coracana L.) germplasm accessions using membership function value at the seedling stage. Will it work on fonio? Or salt-tolerance?
- Adoption and impact of improved amaranth cultivars in Tanzania using DNA fingerprinting. So can we stop calling it underutilized? And start gene-editing it for aroma?
Nibbles: CATIE genebank, Svalbard etc, Medicinal plant genebank, Coconut genebank
- Short, slightly random piece on the CATIE genebank.
- Equally short and equally random piece on genebanks in general, leading with CATIE, closing with Svalbard. I suppose one shouldn’t be looking at a gift horse in the mouth.
- A Ugandan field genebank is suffering from thefts. Maybe we shouldn’t call them banks.
- Jamaica wants a coconut genebank. Hope it has a strong fence.

- The SDGs need proper long-term financing, say Prof. Jeffrey Sachs and co-authors. Maybe he’d like to have a look at the the Crop Trust’s endowment fund for SDG 2.5?
- There’s a 15x return on investment from the Global Biodiversity Information Facility (GBIF)? Ok, do Genesys next.
- Want to revitalize the food system? Think lentils, bananas, kale and walnuts. My take? Why stop there?
- I mean, there’s all sorts of cool pulses besides lentils, nice as they are.
- Really no end to them.
- Want some cock beer with your Lincolnshire beans? I bet you do.
- Shout out for the Access Agriculture farmer-to-farmer educational video platform from the Seed System Newsletter. Nothing on walnuts, alas. Or cock beer.
- As we’re on online resources, there’s also the Support Centre for Agriculture and Nutrition Research (SCANR). It “connects researchers with resources and guidance for carrying out interdisciplinary research related to agriculture, food systems, nutrition, and health.” I wonder what it has to say about walnuts.
- Nut genebank gets an upgrade in Oregon. No, not walnuts, alas. It’s Miller time!
- Lots of genebank action in Hawaii too.
- Livestock also getting the genebank treatment in the US.
- But not just in the US: Norway too. Love these back-from-the-brink stories.
- The regional genebank for the Pacific is one of my favourites.
- It’s up there with that of the World Vegetable Centre, which is getting a write-up in the New Yorker, of all places.
- Of course you can have community-level genebanks too. Here are two examples from India: conserving millets and mangoes.
- Maybe there should be more genebanks for wild food species, but these cool in situ conservation stories will do for now.
- Investing in community farming projects can revitalise degraded lands.
- Those farming project don’t have to involve orphan crops, but it wouldn’t hurt.
- You could do participatory plant breeding on them, couldn’t you. This book says that be just the ticket for rural revitalisation. Lots of revitalisation in these Nibbles.
- They would help with malnutrition where maize biofortification hasn’t worked so well, for example.
- Maize? Maize needs to be decolonized, not biofortified.
- Extension workers need to be better at identifying different crop varieties. IITA is on the case, but doesn’t seem to have thought about putting the data on GBIF. Walnuts next?
- Wait, what’s a variety?
Brainfood: Domestication syndrome, Plasticity & domestication, Founder package, Rice domestication, Aussie wild rice, European beans, Old wine, Bronze Age drugs
- Phenotypic evolution of agricultural crops. Plants have evolved to become bigger, less able to run away, and more delicious to herbivores, and breeders can use insights into that domestication process to develop an ideotype for multipurpose crops adapted to sustainable agriculture.
- The taming of the weed: Developmental plasticity facilitated plant domestication. The authors made plants less lazy, more attractive, and easier to cook — all by simply hanging out with them for a season or two. And so did early farmers.
- Revisiting the concept of the ‘Neolithic Founder Crops’ in southwest Asia. The earliest farmers in the Fertile Crescent did not do the above for just a single, standard basket of 8 crops.
- The Fits and Starts of Indian Rice Domestication: How the Movement of Rice Across Northwest India Impacted Domestication Pathways and Agricultural Stories. Rice began to be cultivated in India in the Ganges valley, moved in a semi-cultivated state to the Indus, got fully domesticated there, then met Chinese rice. No word on what else was in the basket.
- Analysis of Domestication Loci in Wild Rice Populations. Australian populations of wild rice have never been anywhere near cultivated rice, but could easily be domesticated.
- Selection and adaptive introgression guided the complex evolutionary history of the European common bean. The first introductions were from the Andean genepool, but then there was introgression from that into the Mesoamerican, and both spread around Europe. A bit like Indian meeting Chinese rice?
- Ancient DNA from a lost Negev Highlands desert grape reveals a Late Antiquity wine lineage. One thousand year old grape pits from the southern Levant can be linked to a number of modern cultivars, which could therefore be adapted to drier, hotter conditions.
- Direct evidence of the use of multiple drugs in Bronze Age Menorca (Western Mediterranean) from human hair analysis. There was probably not a single package of drug plants either.
