- Solving the mystery of Obake rice in Africa: population structure analyses of Oryza longistaminata reveal three genetic groups and evidence of both recent and ancient introgression with O. sativa. The wild African O. longistaminata is closer to Asian O. sativa than to other African wild species, and shows evidence of ancient introgression from O. sativa in southern Africa. Definitely worth a network.
- The origins and evolutionary history of feral apples in southern Canada. They are mainly recombinants involving early heritage cultivars, with no hybridization with local wild species. So, not like rice in Africa.
- Can seed exchange networks explain the morphological and genetic diversity in perennial crop species? The case of the tropical fruit tree Dacryodes edulis in rural and urban Cameroon. Cities are hotspots of African plum diversity because people bring in tress from all over the place. So, a bit like apples in Canada.

- Genetic diversity within landraces of barley (Hordeum vulgare L.) and its implications on germplasm collection and utilization. Maybe we should do core collections for each landrace?
- Phenotyping and identification of target traits for de novo domestication of wheat wild relatives. Maybe we should try it with that wild African rice too.
Eat this maize podcast
Jeremy’s latest podcast is out, and it’s a doozie. Plus it saves me adding it to the next Brainfood, which is coming soon, don’t worry people.
Modern maize has long been a puzzle. Unlike other domesticated grasses, there didn’t seem to be any wild species that looked like the modern cereal and from which farmers could have selected better versions. For a long time, botanists weren’t even sure which continent maize was from. That seemed to be settled with the discovery in lowland Mexico of teosinte, a wild and weedy relative of maize. But there was a problem. A lot of the later genetic work to understand the transformation of teosinte into maize found remnants of different types of teosinte.
Jeffrey Ross-Ibarra and his colleagues have sorted out the story, which is now more complicated, better understood, and offers some hope for future maize breeding. Their paper was published last week in Science.
Nibbles: USDA germplasm plan, Millet CoP, Seed system resources, Kenyan sorghum Scottish crab apples, Heirloom maize, Yak cheese, Indian mangoes
- The US Department of Agriculture (USDA) has a new National Strategic Germplasm and Cultivar Collection Assessment and Utilization Plan. Quite the tour de force. Now to get it funded.
- Yes, there’s now a community of practice on millets. Joined!
- The Seed System Lab at the Norwegian University of Life Sciences has lots of interesting resources on its new website.
- The latest on the Kenyan genebank’s sorghum work.
- Why wouldn’t Scotland have a crab apple genebank?
- Why Jimmy Red maize is worth saving, despite its faults.
- Yak cheese? Yes, please.
- And nice pics of Indian mangoes to close.
Reasons to be cheerful
Just noticed I haven’t posted in over three weeks. Sorry about that. But there is a good reason: work.
First there was the Global Crop Diversity Summit in Berlin.
Then there was the 10th Session of the Governing Body of the International Treaty on Plant Genetic Resources for Food and Agriculture in Rome. The Summit communique was presented to delegates, who welcomed its call for more support to genebanks.
Then there was the Phase 2 meeting of the Vision for Adapted Crops and Soils (VACS) in New York. That vision will arguably depend on the sort of access to genetic diversity that genebanks provide and the Treaty facilitates.
And now of course there is COP28 in Dubai, with its particular focus on the need for transforming agrifood systems.
Which takes us back to the Summit and its call that we need to empower genebanks if that transformation is going to work. And to the Treaty. And indeed to VACS and its focus on less-known crops.
And actually there has been good news already in Dubai bringing all those strands together. Check out the last item on this list of projects that will be supported by Norway.
But don’t worry, normal service will be renewed here soon.
