- Crop-to-wild gene flow in wild coffee species: the case of Coffea canephora in the Democratic Republic of the Congo. DNA bits diagnostic of domesticated coffee are finding their way into wild rainforest populations, but not all that much.
- The genome and population genomics of allopolyploid Coffea arabica reveal the diversification history of modern coffee cultivars. Diversity was already pretty low in pre-domestication wild arabica, and continued going downhill after that. Time to re-synthesize the crop, I say.
- Beyond the Orthodoxy: An Overview of the Potential of ‘Other’ Coffee Species for Crop Use and their Associated Challenges. All well and good, but don’t forget there’s more to coffee than just arabica and robusta.
- Advancing Coffee Genetic Resource Conservation and Exchange: Global Perspectives and Strategies from the ICC 2024 Satellite Workshop. Time to properly secure all coffee diversity in genebanks, and that includes sorting out ABS.
- Expanding the cacao group: three new species of Theobroma sect. Herrania (Malvaceae: Byttnerioideae) from the Western Amazon Basin. Plenty of “other” cacao species too, and more coming.
- Seed morphometrics unravels the evolutionary history of grapevine in France. There was wild-domesticate geneflow in early grapevines in France as well as in robusta coffee in the DRC, and you don’t need to trace bits of DNA to prove it.
- Characterization and analysis of a Commiphora species germinated from an ancient seed suggests a possible connection to a species mentioned in the Bible. Thousand-year-old seed is a distinct and possibly long-lost species of myrrh. Which ok is not a beverage but still vaguely liquid, at least initially.
- Sesame, an Underutilized Oil Seed Crop: Breeding Achievements and Future Challenges. Ok, since we’re doing liquid-producing crops, let’s include this review of sesame improvement. Lots of wild species to use. No word on wild-domesticate geneflow though.

- 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?

- 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.

- Never thought I’d see the Svalbard Global Seed Vault in Psychology Today, yet here we are.
- The Pacific’s regional genebank is set for more work on lesser-known crops. Too bad most of them won’t be able to go to Svalbard.
- How to make a genebank beautiful as well as sustainable.
- Australia has a rice genebank. For some reason.
- Bangladesh gets a new genebank. Could have sworn it already had one.
- Mutants need a genebank too.
- And inoculants.
- Community-level genebanks have their place too. Though probably not for mutants.
- As long as the farmers get a benefit, of course.
- Tricot is a good way of evaluating all that stuff in genebanks.
- But you should also genotype it.
- Why bother with all this? Andreas Volz has a nice explanation.
- Genetic diversity is all very good, but don’t forget to intercrop.
- Which includes agroforestry.
- For a more varied diet.
- And a better world economy.
- And a more sustainable food system.
The olive’s second act?
Is Xylella — cause of the olive plague that has been stalking southern Europe for a decade — a blessing in disguise for the Salento? Jeremy asks the hard questions in his latest Eat This Podcast. Spoiler alert: Silvestro Silvestori thinks it might just be:
…at the heart of Xylella and the Salento is an identity crisis, that we’re all the children of farmers, we’re all farmers ourselves. And for most people, that’s not the case any longer. And there’s not a lot of industry left here as far as farming. So I think first we have to look at ourselves in the mirror and say, what are we?
Fascinating insights throughout, so listen to the whole thing. And wonder whether this will help.
