Brainfood: Cattle domestication double, Sheep domestication, Lomas in Peru, Sweet potato in Aotearoa, Bananas in SE Asia, African wild eggplants, Brassicaceae conservation review, Vanilla in Madagascar
- Global dispersal and adaptive evolution of domestic cattle: a genomic perspective. The scope of adaptation is pretty amazing, and has been aided by introgression from wild relatives.
- The genomic natural history of the aurochs. Which is just as well because the initial diversity of the domesticate was probably rather limited, at least in Europe.
- The Population History of Domestic Sheep Revealed by Paleogenomes. Early domesticated sheep genomes were pretty dynamic too, sometimes in parallel with shepherds and sometimes not.
- Late pre-Hispanic fog oasis settlements and long-term human occupation on the Peruvian central coast from satellite imagery. No cattle or sheep in pre-Hispanic lomas, but plenty of camelids and crops.
- American sweet potato and Asia-Pacific crop experimentation during early colonisation of temperate-climate Aotearoa/New Zealand. One of those crops was in Aotearoa by the 14th century, which is amazing.
- Musa species in mainland Southeast Asia: From wild to domesticate. Even the very wild species are affected by human use.
- Landscape genomics reveals genetic signals of environmental adaptation of African wild eggplants. Environment is not the main driver of selection, but still pretty important and thus useful in breeding. Kinda like cattle?
- Current status of global conservation and characterisation of wild and cultivated Brassicaceae genetic resources. Gotta conserve those wild relatives probably though, if they are to be used.
- Genome-wide assessment of genetic variation and population structure in cultivated vanilla from Madagascar. The results of a breeding programme 80 years ago involving wild relatives can be seen in the current structure of diversity.
Brainfood: Food systems, Micronutrients, Animal-source foods, Dietary diversity, Opportunity crops, Traditional landscapes, Gastronomic landscapes, Opportunity crops, Biofortification, Fermentation
- Global and local perspectives on food security and food systems. Six experts have their say on how to transform food systems, and dietary diversity seems to be a common (though not a universal) theme. Let’s dig a little deeper into that.
- Global estimation of dietary micronutrient inadequacies: a modelling analysis. A lot of people could probably do with eating more fruits and vegetables, for example.
- Plant-based diets–impacts of consumption of little or no animal-source foods on human health. Some people could probably do with eating more animal-source foods, though. Well, that’s diversity too.
- The association between crop diversity and children’s dietary diversity: multi-scalar and cross-national comparisons. In some places, growing more diverse crops is associated with eating more diverse diets; in other places, not so much. Damn you, nuance!
- Revive and Thrive: Forgotten Crops for Resilient Food Systems. Fortunately, there are more advantages to growing more diverse crops than its possible positive effect on diet diversity…
- Why traditional rural landscapes are still important to our future. …yes indeed there are, especially if they are grown in diverse landscapes.
- Nurturing gastronomic landscapes for biosphere stewardship. The hallowed craft of cooking can help realize those advantages.
- NUS so fast: the social and ecological implications of a rapidly developing indigenous food economy in the Cape Town area. However, growing more diverse crops can have downsides, celebrity chefs etc. notwithstanding.
- Assessing realized genetic gains in biofortified cassava breeding for over a decade: Enhanced nutritional value and agronomic performance. Breeding crops for higher nutritional value comes at a yield price. Which presumably, in some places, for some people, may be worth paying, give all the uncertainties above?
- The future is fermented: Microbial biodiversity of fermented foods is a critical resource for food innovation and human health. Or, we could all ferment more. And maybe get drunk.
Brainfood: EU landraces, EU GIs, Citizen fruit scientists, Nordic potatoes, Czech wheat, German wheat, Wild Brassica collecting, Chinese & European soybeans, Italian goats
- Landrace in situ (on-farm) conservation: European Union achievements. Lots of organizations and farmers are conserving landraces in Europe, in lots of ways, and pretty successfully, but the most sustainable way to do so would be to decrease barriers to their marketing, in particular in the context of organic agriculture.
- An assessment of the implementation of the EU policy for conservation varieties from 2009 to 2023 and its relationship to Geographical Indications. Few European GIs use conservation varieties (i.e. landraces), but this should, and probably will, change.
- New citizen science initiative enhances flowering onset predictions for fruit trees in Great Britain. Imagine doing this for European landraces.
- Genetic markers identify duplicates in Nordic potato collections. Ooops, some alleged landraces in European genebanks turn out to be old improved varieties.
- Curation of historical phenotypic wheat data from the Czech Genebank for research and breeding. You need data on all those landraces if people are going to use them. Citizen scientists might help, I guess.
- Trait-customized sampling of core collections from a winter wheat genebank collection supports association studies. But you need to use that data to create subsets first, and you can do that in lots of different ways, for different purposes: let the German genebank show you how.
- Collecting Mediterranean wild species of the Brassica oleracea group (Brassica sect. Brassica). Even in Europe some gap-filling collecting is still necessary.
- A comparison of Chinese wild and cultivar soybean with European soybean collections on genetic diversity by Genome-Wide Scan. Even breeders in the soybean center of diversity might find material from Europe’s genebanks useful.
- Can Sustainability and Biodiversity Conservation Save Native Goat Breeds? The Situation in Campania Region (Southern Italy) between History and Regional Policy Interventions. Conservation livestock breeds, anyone?
Nibbles: CWR double, Banana threats, Banana collecting, Rice breeding, Cassava breeding, SADC livestock genebank, Community seedbank, Sunflower mapping, Restoration
- Why we need crop wild relatives.
- No, really, we need crop wild relatives.
- The banana is in trouble.
- Which is why we need to conserve banana wild relatives and landraces.
- Lots of wild relatives are conserved in the IRRI genebank mentioned in this Guardian article on breeding low glycemic index and high protein rice. Some of them may even have been used in this work. May look that up one day.
- I doubt that IITA used wild relatives in breeding these high quality cassava varieties, but there’s always a first time, and there may even be some in its genebank. I should probably look but I don’t have time for this rabbit hole today.
- And livestock get conserved in genebanks too, though not as much as crops. I’m really not sure how many livestock wild relatives are in the world’s genebanks, but my guess is not many.
- Farmers conserve crop (and livestock) diversity too, of course. And sometimes even their wild relatives.
- It’s amazing what can be done from space to figure out what farmers are growing. This is an example of sunflower in Ukraine, but one day we’ll even be able to locate crop wild relatives, I’m sure.
- To finish off, a reminder that we need conserved seed of wild species for more than just breeding: restoration too.
