- 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.
Nibbles: Cropscapes, Ecuador cacao, Nigerian yams, Lima bean show, Mesopotamian cooking, Nepal seed banks, RNA integrity, China genebanks, Cryo comics, Greening
- The authors of book “Moving Crops and the Scales of History” have been awarded the Edelstein Prize 2024 for their work to “redefine historical inquiry based on the ‘cropscape’: the assemblage of people, places, creatures, technologies, and other elements that form around a crop.” Let’s see how many cropscapes we can come up with today.
- Here’s one. The Ecuador cacao genebank gets some much-needed help.
- Digging into Nigerian yams. And another.
- Castle Hex has a programme on Lima beans on 7-8 September. Sounds like fun.
- What if you can’t work out what the crops are, though? As in Mesopotamian recipe books, for example.
- The community seed banks of Nepal have a new website. Good news for those Nepalese cropscapes.
- A new project is testing RNA integrity number (RIN) as a metric of seed aging for a bunch of rare wild plants. One day maybe community seed banks will be using it.
- China has inventoried its agricultural germplasm. Will it be applying RIN next?
- The French are using bandes dessinées to teach about cryopreservation of animal genetic resources. Livestockscapes?
- Some drylands are getting greener and some people think that’s a problem. Always something.
Nibbles: Forest seed collecting, Colombian maize, Türkiye & China genebanks, Community seedbank trifecta, Wheat breeding, Rice breeding, Bean INCREASE, WorldVeg regen, UK apples, Rangeland management
- How to collect forestry seeds.
- Whole bunch of new maize races collected in Colombia.
- The Türkiye national genebank in the news. Lots of collecting there. Though maybe not as much as in this genebank in China.
- But small communities need genebanks too. Here’s an example from Ghana. And another from India. And a final one from the Solomon Islands.
- Need to use the stuff in genebanks though. Here’s how they do it in the UK. And in Bangladesh. And in Europe with the INCREASE project, which has just won a prize for citizen science. And in Taiwan. Sort of citizen science too.
- Collecting apples in the UK. Funny, the canonical lost-British-apple story appears on the BBC in the autumn usually. Kinda citizen science.
- Or we could do in situ conservation, as in this South African example… Just kidding, we all know it’s not either/or. Right? Probably a good idea to collect seeds is what I’m saying. Could even do it through citizen science.
Nibbles: SPAM2020, Pullman genebank, Svalbard, Olive plague, Rice diversity, Vanilla threat, Gum rockrose, VACS demand, AI double, Food & climate change
- The latest version of the SPAM global crop area distribution model is out. You can play with it here.
- Some bullet points on the USDA’s National Plant Germplasm System outpost in Pullman.
- Yes, the above references Svalbard, as does this piece on Spanish tomatoes.
- Pity we can’t put olives in Svalbard, but there’s a another way to protect olive diversity.
- A breakdown of rice colour diversity. A lot of this stuff will be in Svalbard, with any luck.
- Vanilla will also need attention.
- But gum rockrose seems to be taken care of, at least in Bulgaria. It’s what you make Holy Chrism with.
- So there’s bound to be demand for it, at least in some quarters. Unlike for other opportunity/orphan/neglected crops, but GAIN is on it.
- And if all else fails there’s always AI, be it to fight pests and diseases or find cool plants out in the jungle.
- Why does all this matter? Because of the climate F-word.
Brainfood: Yield gap, Domestication & breeding, TEK, Breeding gourds, Breeding pearl millet, Breeding peas, Banana seed systems, Breeding bees
- Global spatially explicit yield gap time trends reveal regions at risk of future crop yield stagnation. For 8 of 10 major crops, yield gaps have widened steadily from 1975 to 2010 over most areas, and remained static for sugar cane and oil palm. Time to turbo-charge the breeding?
- Domestication and the evolution of crops: variable syndromes, complex genetic architectures, and ecological entanglements. If you want to turbo-charge breeding, you need to understand (among other things) the ecological context of domestication.
- Including Traditional Ecological Knowledge (TEK) in Agricultural Research: Guidelines and Lessons Learned. I suspect Traditional Ecological Knowledge can help with figuring out the ecological context of domestication.
- High levels of genetic variation and differentiation in wild tropical gourds provide a novel resource for cucurbit crop improvement. Ok, but ecological knowledge would like a word.
- Understanding genetic diversity in drought-adaptive hybrid parental lines in pearl millet. Any link to ecology of original collecting sites, I wonder?
- Genetic Diversity and Population Structure Analysis of a Diverse Panel of Pea (Pisum sativum). Again, ecological knowledge conspicuous by its absence. Maybe the passport data just weren’t up to it?
- Banana seed exchange networks in Burundi – Linking formal and informal systems. Yes, yes, it’s not just about the breeding, the seed system also has to work.
- Editorial: Current status of honey bee genetic and breeding programs: progress and perspectives. Pollinators need breeding programmes too.
