- Genetic diversity goals and targets have improved, but remain insufficient for clear implementation of the post-2020 global biodiversity framework. The struggle to ensure recognition of the importance of measuring genetic diversity is real, despite the available tools. And despite the range of uses to which the results can be put, as illustrated in the following papers.
- DNA barcoding markers provide insight into species discrimination, genetic diversity and phylogenetic relationships of yam (Dioscorea spp.). Measuring genetic diversity can help you tell species apart.
- Genetic diversity and population structure of barley landraces from Southern Ethiopia’s Gumer district: Utilization for breeding and conservation. Measuring genetic diversity can help you decide what’s new and what to use in breeding.
- Management of genetic erosion: The (successful) case study of the pear (Pyrus communis L.) germplasm of the Lazio region (Italy). Measuring genetic diversity can help you detect genetic erosion and figure out what to do about it.
- Genetic and Pomological Determination of the Trueness-to-Type of Sweet Cherry Cultivars in the German National Fruit Genebank. Measuring genetic diversity can help you fix mistakes in genebanks.
- Genetic diversity and local adaption of alfalfa populations (Medicago sativa L.) under long-term grazing. Measuring genetic diversity can help you identify adaptive genes.
- A common resequencing-based genetic marker data set for global maize diversity. Measuring genetic diversity can help you pinpoint useful flowering genes.
- Genome-wide association study of variation in cooking time among common bean (Phaseolus vulgaris L.) accessions using Diversity Arrays Technology markers. Measuring genetic diversity can help you identify carbon-friendly genes.
- Dissecting the genetic architecture of leaf morphology traits in mungbean (Vigna radiata (L.) Wizcek) using genome-wide association study. Measuring genetic diversity can help you find plants with nice leaves.
- Genetic Diversity Strategy for the Management and Use of Rubber Genetic Resources: More than 1,000 Wild and Cultivated Accessions in a 100-Genotype Core Collection. Measuring genetic diversity can help you go from over 1000 accessions to under 100.
- Sustainable seed harvesting in wild plant populations. Measuring genetic diversity can help you model optimal germplasm collecting strategies.
- Genetics of randomly bred cats support the cradle of cat domestication being in the Near East. Measuring genetic diversity can tell you where the cat was domesticated.
- Bacterial species diversity of traditionally ripened sheep legs from the Faroe Islands (skerpikjøt). Measuring genetic diversity can help you figure out how to ripen sheep legs properly.
Nibbles: Green seeds, Yam bean, Aussie wild tomato, Einkorn trial, US sorghum, Ethiopian forages tricot, Cuisine diversity, Apple catalogue, Hittite crash, Black Death
- Let’s say we wanted to transition to a more local and low-input production system in Europe. What seeds would we need and where would we get them from? The Greens/EFA in the European Parliament have some ideas.
- IITA is pushing the yam bean in Nigeria. Europe next?
- More on that new Australian wild tomato from a couple of years back. With audio goodness.
- The largest ever einkorn variety comparison trial makes the German news. Well, makes a press release anyway. Yam bean next?
- Another continent, another ancient grain: sorghum in the US. Yam bean next?
- The Ethiopia Grass project aims to improve livestock production, food crop yields AND soil quality. The trifecta!
- Nice infographics displaying dodgy data on the most common ingredients in different cuisines. Yam bean and einkorn nowhere to be seen.
- Cool community-created online catalogue of British apples. Looking forward to the yam bean one.
- It was drought that did for the Hittites, not lack of yam beans. Sea Peoples unavailable for comment.
- It was Yersinia pestis from Issyk-Kul that nearly did for Europe in the Middle Ages. Yes, you can study the genetic diversity of ancient deadly bugs and well as that of crops like yam bean and einkorn.
Nibbles: Mugumu, Gates, Fixation, OSA, USDA, Panicum, Digitaria, Britgrub, Wheat, ICRISAT, Svalbard
- Blog post on the importance of the mugumu tree in Kikuyu culture.
- Alas, no sign of mugumu trees on the Kenyan farm visited by Bill Gates recently. But there were chickens, drought-tolerant maize and mobile phones…
- …and there may soon be crops engineered for nitrogen fixation too, if his foundation’s project with the University of Cambridge comes through.
- Speaking of maize, here’s a nice illustrated story of how the Organic Seed Alliance is helping farmers grow their own tortilla corn in the Pacific Northwest.
- To generalize and contextualize the above, read this USDA e-book on plant collections and climate change.
- Dr Giedre Motuzaite Matuzeviciute just got a grant to study broomcorn millet domestication and dispersal in Central Asia. There may be lessons for present-day adaptation to climate change, says the blurb.
- There are probably lessons about adaptation to climate change also to be had from Kew’s work on fonio and other traditional crops in Guinea.
- I wonder if Kew boffins are also working on bere, perry and other endangered British foods though.
- It’s always nice to see someone first learn about genebanks, and how they can help with the whole climate change thing.
- Meanwhile, in India, ICRISAT gets a stamp, which however doesn’t look very much like India or ICRISAT to me. Plenty of broomcorn millet in its genebank, by the way.
- Plenty of seeds from the ICRISAT genebank in Svalbard, as Asmund Asdal will no doubt point out on 10 February.
Nibbles: Fancy fungus, Fancy CWR book, Fancy dataset, Fancy food, Fancy wheat collection, Fancy diet, Fancy seeds, Fancy agriculture
- Symbiotic fungus can help plants and detoxify methylmercury.
- Very attractive book on the wild tomatoes of Peru. I wonder if any of them eat heavy metals.
- There’s a new dataset on the world’s terrestrial ecosystems. I’d like to know which one has the most crop wild relative species per unit area. Has anyone done that calculation? They must have.
- Iran sets up a saffron genebank. Could have sworn they already had one.
- The Natural History Museum digs up some old wheat samples, the BBC goes a bit crazy with it.
- Paleolithic diets included plants. Maybe not wheat or saffron though.
- Community seedbanks are all the rage in Odisha.
- Seeds bring UK and South Africa closer together. Seeds in seedbanks. Not community seedbanks, perhaps, but one can hope.
- Can any of the above make agriculture any more nutrition-sensitive? I’d like to think yes. Maybe except for the mercury-eating fungus, though you never know…
Brainfood: Genetic erosion, Ecosystem services, Cereal mixtures, Natural enemies, Soil microbiome double
- Genetic diversity loss in the Anthropocene. Don’t get excited, I don’t think the method translates to cultivated species, but fancy maths says we’ve lost on average 10% of the genetic diversity within species.
- A graphical causal model for resolving species identity effects and biodiversity–ecosystem function correlations. Yeah, but don’t forget that species level diversity is important too. Or rather, diversity of functional traits among species.
- Cereal species mixtures: an ancient practice with potential for climate resilience. A review. Species level diversity in the same farmer’s field is being forgotten, and that’s bad.
- Microbiomes in agroecosystem: Diversity, function and assembly mechanisms. Even soil microbial diversity is important…
- Association analyses of host genetics, root-colonizing microbes, and plant phenotypes under different nitrogen conditions in maize. …but the effects of soil microbial diversity can get quite complicated, and interact with the genetic diversity of crop plants. Which we may or may not have lost an average 10% of.
- Direct and indirect effects of management and landscape on biological pest control and crop pest infestation in apple orchards. Yeah, but species diversity can be bad too.
