Nibbles: Fonio beer, ICRISAT seed kits, Dark Emu, China potatoes, 3D genebank, Bioculture, Microbiome genebank, Nutrition, Michigan kiwi
- You can make beer from fonio.
- ICRISAT providing Niger and Chad with sorghum and pearl millet seed kits. Fonio next?
- No, Echinochloa turneriana next. In Australia. I love the Dark Emu Hypothesis, and not least for its name.
- CIP is helping China improve its potato crop.
- Won’t be long before China’s genebank has 3D images of all its holdings. I’d love to see the potatoes.

Liberating heirlooms
Jeremy’s latest Eat This Newsletter has a dissection of the recent piece on heirlooms from The Guardian that we Nibbled a couple of days back. Plus a whole bunch of other interesting stuff, from food riots to Peruvian limes. Read it!
Intellectual property rights and heirloom seed savers are doing their best to keep things just the way they are, but is that a good thing? The heirlooms of today were created to meet the needs of yesterday, and that’s fine for people who still have those needs. But where are the breeders meeting the needs of non-industrial growers today? They are around, of course, but Chris Smith, writing in The Guardian, thinks seedsavers should stop obsessing over heirloom seeds and let plants change.
He definitely has a point. Laser-like focus on variety preservation does block the possibility of adaptive change to new circumstances. But anyone who know how to keep an open-pollinated variety pure already knows enough to cultivate more diversity and select from that, if they choose to. A farmer like Chris Smith has the land and the inclination to do both, and it doesn’t seem to stop the seed enterprises with which he is associated from offering presumably true-to-type heirloom varieties. I suppose what I am saying is to let a thousand flowers bloom. Preserve the old varieties and use them, with perhaps a pinch of commercial and genebank varieties in the mix, to create and select tomorrow’s heirlooms.
Brainfood: Maize, Chickpea, CWR, Canola, Coconut, Avocado, Eggplant, Carrot, Watermelon, Citrus, Potato, Pearl millet, Roses
- 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.
