- Towards a practical threat assessment methodology for crop landraces. Basically red listing for landraces.
- Preserving traditional systems: Identification of agricultural heritage areas based on agro-biodiversity. First places to apply the above?
- Genetic erosion within the Fabada dry bean market class revealed by high-throughput genotyping. Would have been nice to apply the above before doing this study.
- Restoration of the traditional high-altitude rice variety Dumbja in Bhutan. Highlights one of the problems with monitoring threats to landraces, i.e. how to define the landrace.
- Identifying genetically redundant accessions in the world’s largest cassava collection. About half of over 5000 genebank accessions were unique. Easier to recognize cassava landraces I guess.
- Agricultural commercialisation among women smallholder farmers in Nigeria: Implication for food security. Will commercialization help preserve some landraces but threaten others?
- The groundnut improvement network for Africa (GINA) germplasm collection: a unique genetic resource for breeding and gene discovery. Over a thousand accessions that will be just fine.
- An Appropriate Genetic Approach to Endangered Podolian Grey Cattle in the Context of Preserving Biodiversity and Sustainable Conservation of Genetic Resources. The livestock people monitor threat to breeds all the time, it seems.
Nibbles: Cider exhibit, Dog domestication, Nordic rye, Orkney barley, Tunisian wheat, IPR in Kenya, Future Seeds, Seed & herbarium resources
- The Museum of Cider has an exhibition on “A Variety of Cultures.”
- Nice podcast rounding up the latest on dog domestication.
- Useful summary of the history of rye in the Nordic countries since it replaced barley in the Medieval period.
- They didn’t give up barley in the Outer Hebrides.
- The Tunisian farmer goes back to wheat landraces (I think).
- The Kenyan farmers who want to exchange landraces.
- El Colombiano visits Future Seeds, evokes The Walking Dead.
- Seed saving resources from the California Seed Bank and the herbarium at the University of California, Berkeley.
Nibbles: Cheese microbes, OSSI, Mung bean, Sustainable ag, Agroecology, Collard greens, African orphan crops, Olive diversity, Mezcal threats, German perry, Spanish tomatoes, N fixation
- A sustainable blue cheese industry needs more microbial diversity.
- The Open Source Seed Initiative gets written up in The Guardian. Looks like we need something similar for cheese microbes.
- The Guardian then follows up with mung bean breeding and fart jokes.
- But then goes all serious with talk of trillions of dollars in benefits from sustainable food systems. Diversity not mentioned, alas, though, so one wonders about the point of the previous pieces.
- Fortunately Indigeneous Colombian farmers have the right idea about sustainability.
- Collard greens breeders do too, for that matter.
- More African native crops hype for Dr Wood to object to. Seriously though, some crops do need more research, if only so they can be grown somewhere else.
- There’s plenty of research — and art for that matter — on the olive, but the international genebanks could do with more recognition.
- The mezcal agave, on the other hand, doesn’t seem to have much diversity in genebanks, and it is threatened in the wild.
- Perry culture in Germany is also threatened. Pretty sure there are genebanks though.
- This piece about tomato diversity in Spain is worth reading for many reasons (heroic seed saving yada yada), but especially for the deadpan take on the Guardia Civil at the end.
- Maybe we could breed some of those tomatoes to fix their own nitrogen. And get the Guardia Civil to pay for it.
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.
Nibbles: Public breeding, Millet Man, Strampelli museum, Ghana community seedbanks, genebank trifecta, CWR, Illegal Canadian potatoes, Açaí GI, Mayocoba bean, Spartan Actinidia, Bitters
- Public sector plant breeders are disappearing.
- The Millet Man of India is still there though. And why he’s important.
- A museum to public sector breeder Nazareno Strampelli appears in Italy.
- Another couple of community genebanks appear in Ghana.
- We can never have too many discussions on the importance of genebanks, so here’s another one. Not much on the community sort, though. Here’s another example: Ireland. Even the Arab States of Asia want one!
- And a deep dive on crop wild relatives in genebanks to round things off.
- A community saves illegal potatoes in Canada. Yeah, I know, there’s a lot to unpack there.
- Maybe that humble illegal potato needs a geographic indication, like that superfood, açaí.
- The Mayocoba bean as a superfood is a bit of a stretch, but there’s plenty of other pulses out there making waves.
- The Michigan State kiwi could probably do with a geographic indication too, come to think of it. Cold-hardy and smooth-skinned? Super!
- Ok, this is probably the last Nibbles before Christmas, so let’s celebrate with a drink: with bitters of course.
