- There’s a celebration of the thinking of Robert Chambers over at IDS Bulletin. He’s been advocating for participation in development and the importance of Indigenous knowledge, among other things, for 50 years.
- The Center on Global Food and Agriculture has a report out called “Defining the Path to Zero Hunger in an Equitable World” which basically tries to add humanitarian assistance to the old food-climate-biodiversity nexus. Crop diversity is nowhere to be found among the “catalyzing ideas,” but one of those is investing in “force multipliers,” and that includes agricultural research and development. Participatory agricultural research and development, presumably?
- Meanwhile, China has collected 124,000 crop diversity samples.
- And a Spanish microbiologist has collected 3,600 bacteria.
- The PNAS Special feature: Harnessing crop diversity, organized by Susan McCouch, Loren Rieseberg and Pamela Ronald, got a nice write-up in the latest Plant Science Research Weekly. But what would Robert Chambers say? Anyway, should I do a special Brainfood on it? Let me know in the comments, as the cool kids say.
Brainfood: Genomics for conservation and use edition
- How genomics can help biodiversity conservation. Let’s find out, but let’s broaden it to use as well, shall we? On the assumption that what’s good for conservation is good for use, and vice versa.
- Genetic and genomic interventions in crop biofortification: Examples in millets. Genomics can help you get more nutritious millets, and also use millets to improve the nutritive content of other cereals too.
- Genomics and biochemical analyses reveal a metabolon key to β-L-ODAP biosynthesis in Lathyrus sativus. Genomics can help you figure out ways to decrease the toxicity of grasspea.
- Extensive crop–wild hybridization during Brassica evolution and selection during the domestication and diversification of Brassica crops. Genomics can help you figure out the evolutionary history of crops…
- Molecular characterization of Brassica genebank germplasm confirms taxonomic identity and reveals low levels and source of taxonomic errors. …assuming you have you accessions labelled correctly that is.
- Dual domestications and origin of traits in grapevine evolution. Genomics can help you figure out the evolutionary history of crops. No, wait, we already had that one…
- Balancing grain yield trade-offs in ‘Miracle-Wheat’. Genomics can help you figure out the best phenotype in wheat.
- Focusing the GWAS Lens on days to flower using latent variable phenotypes derived from global multienvironment trials. Genomics can help you figure out the best phenotype in lentils too.
- Awned versus awnless wheat spikes: does it matter? Although actually you don’t necessarily need genomics to help you figure out the best phenotype in wheat. But let’s get back on track.
- SNP Diversity and Genetic Structure of “Rogosija”, an Old Western Balkan Durum Wheat Collection. That’s better. Genomics can help you figure out that a wheat collection can consist of distinct ecogeographic groupings.
- Repeatability of adaptation in sunflowers: genomic regions harbouring inversions also drive adaptation in species lacking an inversion. Genomics can help you figure out what’s behind local adaptation in crop wild relatives.
- Re-evaluating Homoploid Reticulate Evolution in Helianthus Sunflowers. Genomics can help you figure out the evolutionary history of crop wild relatives. Where have I heard that before?
- A thousand-genome panel retraces the global spread and adaptation of a major fungal crop pathogen. Genomics can help you figure out the evolutionary history of plant pathogens too. Here’s a Twitter thread from one of the authors with lots of maps to prove it.
- Honey bee populations of the USA display restrictions in their mtDNA haplotype diversity. Yeah, you guessed it, pollinators too.
- Mezcal worm in a bottle: DNA evidence suggests a single moth species. I rest my case.
Brainfood: Why measure genetic diversity?
- 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.
