- Will a plant germplasm accession conserved in a genebank change genetically over time? Sure, change is inevitable, but it can be minimized, and some can be accepted.
- Cocoyam (Xanthosoma sagittifolium (L.) Schott) genetic resources and breeding: a review of 50 years of research efforts. Conventional breeding, based on inducing flowering, is possible, but will require more international exchange of germplasm. I hope someone is saving the seeds.
- Pollen banking is a critical need for conserving plant diversity. Even if it changes genetically over time.
- Applications of dry chain technology to maintain high seed viability in tropical climates. You’ve got to dry your seeds fast and hard. Probably your pollen too, come to that.
- Harmonize rules for digital sequence information benefit-sharing across UN frameworks. The big question is, should there be a single trigger point for monetary benefits, or separate ones for each treaty? At least the sequences do not change over time. But what about if the accessions from which they are derived do?
- Involving citizens in monitoring the Kunming–Montreal Global Biodiversity Framework. Yes, let’s get citizens to help us monitor all that change.
Nibbles: IUCN report, Land Institute, Climate smart beer, BioLeft seeds, Cryo coral
- Big IUCN report says that biodiversity and agriculture are in conflict, they don’t really need to be, but it’s really complicated for them not to be. So that’s us all told.
- If only annual crops were perennial, for example, eh?
- If only we incorporated more sustainable agriculture in education, for example, eh? Apart from anything else we could still have beer. No word on the role of perennial barley though.
- If only improved seeds were open source, for example, eh?
- If only we could cryopreserve coral, for example, eh? Wait, what?
Brainfood: Beverage edition
- 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.
Nibbles: Svalbard Global Seed Vault, CePaCT genebank, CIAT genebank, Australia rice genebank, Bangladesh genebank, Maize mutants garden, Inoculants genebank, Millets community seedbank, Payments for Agrobiodiversity Conservation Services, Triadic Comparison of Technology Options, Crop diversity, Intercropping, Agroforestry, Diet diversity, World economy, Sustainable food
- 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.

- Optimizing the accession-level quantity of seeds to put into storage to minimize seed (gene)bank regeneration or re-collection. = [nvt × 3]+[nd × (y × x)]+ qmin if you must know.
- A pragmatic protocol for seed viability monitoring in ex situ plant genebanks. Formulas are good, but you need some flexibility too.
- A power analysis for detecting aging of dry-stored soybean seeds: Germination versus RNA integrity assessments. Germination testing is good, but RNA integrity assessment is better, especially early on in storage.
- Sampling strategies for genotyping common bean (Phaseolus vulgaris L.) Genebank accessions with DArTseq: a comparison of single plants, multiple plants, and DNA pools. Pool the DNA from 25 plants for best results. They don’t even have to be alive :)
- Plant Cryopreservation: Principles, Applications, and Challenges of Banking Plant Diversity at Ultralow Temperatures. No seeds? No problem. Still a lot of research needed though.
- Potato soup: analysis of cultivated potato gene bank populations reveals high diversity and little structure. This should help figuring out what to put in cryo, I guess.
- Developing new in vitro micropropagation and cryopreservation techniques in coconut. A little less research needed.
- SNP genotyping Dutch heritage apple cultivars allows for germplasm characterization, curation, and pedigree reconstruction using genotypic data from multiple collection sites across the world. Now do coconuts.
- Vulnerability of pear (Pyrus) genetic resources in the U.S. It’s moderate to high. No word on what the vulnerability of coconut is.
- First plant conservation translocation in Armenia: restoring globally threatened wild pear populations. A little less vulnerable?
- Designing celebrity-endorsed behavioral interventions in conservation. I’d like to get a celebrity to endorse coconut cryoconservation. Mr Freeze?
- The seeds are coming home: a rising movement for Indigenous seed rematriation in the United States. Makes all the formulas and testing and gadgets worthwhile.
- Farmers’ Rights in the Plant Treaty: interrelations and recent interactions with other international regimes and processes. Will require all those formulas and testing and gadgets.
