- 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.
Nibbles: Trevor Williams, ICRISAT genebank, Irish seedbank, Domestication video, COP27 genebank webinar, Pasturelands, Big Food report, Mesopotamian cooking
- The late Prof. Trevor Williams, one of the pioneers of genebanking, in the news.
- The President of Niger visits a genebank, makes the news.
- Irish seedbanking in the news.
- Dr Mark Chapman on how to study domestication using seeds in genebanks.
- COP27 webinar on using seeds in genebanks for climate change adaptation.
- Pasturelands: sometimes genebanks are not enough. Though even then I bet they can help.
- Big Food still not doing much to support genebanks, despite reports such as this.
- A book on ancient Mesopotamian cooking. Who can think of the best link to genebanks?
A global overview of domestication
I think I may have missed the PNAS paper “Current perspectives and the future of domestication studies” when it came out in 2014. I certainly can’t seem to find it on the blog here. But I’m glad it got mentioned recently on Twitter because it has something I’ve been searching for on and off for a while now: a reasonably up-to-date timeline of crop and livestock domestication. Which I’m therefore happy to reproduce here. I’d love to read a global narrative of the history of domestication linking all these together.
Brainfood: Opuntia breeding, Teosinte genes, Sugarcane breeding, Proso diversity, Watermelon diversity, Wheat pre-breeding, Sorghum wild relatives, Grasspea evaluation, Banana domestication, Pea pan-genome, Bambara diversity
- Needs and strategies for breeding and sustainable use of genetic resources in Opuntia. Surely there are molecular markers for spinelessness by now?
- Teosinte confers specific alleles and yield potential to maize improvement. There are 71 QTLs associated with 24 differential traits between maize and teosinte.
- A short review on sugarcane: its domestication, molecular manipulations and future perspectives. Forget sugar or fuel, the future is vaccine production.
- SNP discovery in proso millet (Panicum miliaceum L.) using low-pass genome sequencing. Ok, but why are the South Asian accessions so different from everything else?
- Meta-analysis of qualitative and quantitative trait variation in sweet watermelon and citron watermelon genetic resources. Rob citron to pay sweet watermelon.
- Genomics-informed prebreeding unlocks the diversity in genebanks for wheat improvement. How I learned to stop worrying and love non-adapted germplasm.
- Wild Sorghum as a Promising Resource for Crop Improvement. Oooh, I like the idea of de novo domestication of Australian wild sorghum species.
- 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.
- Genetic diversity and population structure analyses of South African Bambara groundnut (Vigna subterranea [L.] Verdc) collections using SNP markers. Two heterotic groups to play around with.
Nibbles: New cassava, Community seedbank double, Rwandan beans, Knotweed et al., Seed systems, Adam Alexander, Uruguay genebank, Kelp biobank
- There’s a new cassava in town in Kenya.
- I wonder if it will end up in a community “seed” bank.
- …because they swear by them in Zimbabwe.
- Cassava is not the only American crops that’s important in parts of Africa: the cultural appropriation of beans in Rwanda.
- Some American crops didn’t make it very far out of America.
- Be it beans, cassava or sump/knotweed, what’s needed is a Quality-Declared Seed (QDS) system. Right?
- Well you also need someone to go around collecting the stuff in the first place.
- But don’t forget to back everything up in Svalbard, like Uruguay is doing.
- Well maybe not everything.
