- China is building its germplasm collection at the National Frigid Zone Crop and Soybean Germplasm Resources Mid-term Bank in Harbin. Cool.
- Driscoll’s helped build China’s blueberry industry, then discovered that knowledge, infrastructure and genetics have a habit of escaping. Not so cool.
- Meanwhile, the Philippines wants its rice collection to hit 21,000 varieties by the end of the year. IRRI unavailable for comment.
- Italy is establishing a major global olive genebank. Unclear where it fits in with other major global olive genebanks, but some redundancy is good.
- FAO showcases Globally Important Agricultural Heritage Systems, where crops, landscapes and traditional knowledge have survived together. Like olives in Italy, I guess.
- The mangelwurzel is making a comeback, because apparently forgotten root vegetables just need better publicity, and not a fancy GIAHS.
- Ohio growers are trying to save the pawpaw just as Americans are discovering it, partly because of better publicity.
- BeanGPT is bringing AI to breeding and farming beans. Maybe it can help the mangelwurzel and pawpaw too?
Brainfood: From data to action
- A three-decade-long analysis shows rising threatened species and responsibility gaps in global supply chains. Data says that we must make responsibility for biodiversity traceable from production to final demand.
- Development of an evidence-based integrated germplasm prioritization framework for conservation and breeding. Data says: here’s how to extract some defensible conservation and breeding priorities from this large collection.
- A methodological framework for the standardised evaluation of olive genetic resources: GEN4OLIVE harmonized protocols. Data says that we should standardise phenotyping across countries to make olive germplasm more useful in breeding.
- High-throughput phenotyping of Bambara groundnut [Vigna subterranea (L.) Verdc.] seed morphometrics using videometer. Data says that we should use multispectral imaging to really speed up seed characterization and breeding in Bambara groundnut.
- Predicting the cross-continental spread of the cassava brown streak disease epidemic in sub-Saharan Africa. Data says that we must strengthen surveillance and delivery systems for clean planting material before cassava brown streak disease reaches Nigeria.
- The Sustainability of Robusta Coffee Under Global Change—A Review. Data says that we must match robusta production to genuinely suitable environments, plus invest in lower-input cultivation and alternative coffee species.
- Borassus Akeassii Facing Societal and Environmental Challenges: Case Study of the Gouin Society of Southwestern Burkina Faso. Data says that we need to conserve this multipurpose palm once central to Gouin livelihoods together with the local knowledge and practices that make it useful.
Nibbles: Pasiega cow, Goat-cow, Badri cow, Zimbabwe festival, Heirloom apples, South Korea genebank, Marmottier, Radiation breeding
- Cantabria is putting the Pasiega cow in the bank. Just in case.
- Spain’s “goat-cows” are fighting wildfires the old-fashioned way: by eating the fuel. I hope they’re in the bank too.
- India has made a Badri calf in a lab. Conservation meets IVF.
- Old apples are having a revival. Turns out forgotten apple varieties can taste pretty good. Well I never, is it that time of year already?
- Zimbabwe’s Mbire district celebrates seed, food and culture with a festival. What, no cows? Or apples?
- South Korea is looking for partners to save climate-resilient plants. A seed vault is better with friends.
- The marmottier can’t decide whether it’s a plum or an apricot. Botanists sympathise.
- In the atomic age, gardeners irradiated seeds and waited for something interesting to grow. Sometimes it did.
Nibbles: Frafra, Seed multiplication, Quality seeds, Balearic genebank, Indigenous trees double, Bruno cart, Belgian wild yeast
- Frafra potato is having a moment: an indigenous West African tuber, adored locally and mostly ignored by science, out looking for its big commercial break.
- Speaking of breakthroughs, this bus driver found his own, swapping the wheel for seed multiplication and turning five acres into a livelihood, proof that sometimes the missing link in a seed system is just someone willing to do the unglamorous middle bit well.
- Which is, per Farming First, precisely Africa’s problem at scale: only 2.5% of smallholder seed in Sub-Saharan Africa comes from formal seed companies, so a few million more bus-driver-style multipliers wouldn’t hurt.
- Meanwhile in the Balearics, the opposite direction of travel: the local seed bank is expanding to rescue tomatoes, onions and broad beans, and is looking for farmers willing to take them back.
- Indigenous fruit trees in Malawi turn out to fight malnutrition and biodiversity loss at once. Happy coincidence?
- Getting those trees into the ground well needs the same unglamorous groundwork as any good crop seed system: a Mongabay commentary argues that restoration campaigns skipping Indigenous and local seed knowledge are optimising for trees planted, not trees that survive.
- And once you’ve got the saplings in the ground, you might want to monitor how they’re doing: enter Bruno, a pushcart rigged with mobile phones that can collect field data. And not just for breeders.
- Finally, proof that not all genetic-resource hunting needs a genebank: Brussels brewers are getting people to comb the city for wild yeast, because the raw materials for a proper lambic turns is hanging around in urban trees.
Brainfood: Tree conservation from assisted migration to cryo
- The potential effect of megafaunal extinctions on modern conservation of horse chestnut Aesculus hippocastanum. The extinction of large seed-dispersing mammals (i.e. elephants) may explain why horse chestnut failed to recolonise Europe after the last ice age, pointing to assisted migration as a conservation option.
- Mapping melliferous tree species in Kenya via one-class classification with hyperspectral unsupervised domain adaptation. Hyperspectral remote imagery and fancy maths can accurately identify and locate Kenya’s honey trees, potentially supporting both conservation and beekeeping. Brave new world. Elephants not involved.
- Everyday agroecologies in the Mixteca Alta, Mexico: gendered knowledge and practices in homegarden agroecosystem management. Women’s knowledge helps sustain homegardens as reservoirs of agrobiodiversity and climate-adaptation spaces, embedding many interesting wild and cultivated trees, along with much else, in wider systems of knowledge and resource management.
- Integrative DNA barcoding and multimethod species delimitation reveal marker performance in the genus Ficus L. (Moraceae). Takes on the old taxonomic problem of where one fig species ends and another begins. Ficus is an especially resonant group for today’s tree-themed roundup: taxonomically challenging, ecologically consequential, economically and culturally important, tied to famously specialised pollination relationships. “Integrative” means the usefulness of a DNA marker must be tested against other evidence and against the particular boundaries one is trying to recognise.
- Chloroplast phylogeographic analysis guides the source tracing and conservation strategies of the endangered Magnolia kwangsiensis Moving down one biodiversity level, mapping maternal genetic structure helps identify appropriate seed sources for conservation and restoration, rather than treating all populations as genetically equivalent. Next comes feeding the seeds to passing elephants.
- Development of a simple and easily interpretable cultivar identification system using 18 insertion/deletion (InDel) markers in Japanese pummelo (Citrus maxima). Really simple markers can identify Japanese pummelo cultivars, and even reveal clues about their parentage.
- К 100-летию отдела генетических ресурсов плодовых культур ВИР. (On the 100th Anniversary of the Fruit Crop Genetic Resources Department of VIR). A century-long institutional case study in tree (ok, and shrub) conservation at scale: some 19,000 fruit, nut and berry accessions now held in field genebanks across ten Russian field stations, each sited in the climate zone that suits what it conserves.
- Cryopreservation strategies for trees: Leveraging organogenesis and somatic embryogenesis for effective conservation. Combining ultra-low-temperature storage with making shoots or roots from an explant tissue and making embryo-like structures from non-reproductive cells offers ways to emulate seeds when the real things cannot be easily stored in the usual way, field genebanks cannot be guaranteed to last 100 years, and there are no elephants around.
