- New ICRISAT varieties of sorghum, pearl millet and pigeonpea are doing well in drought-hit Kenya. For now, at least: something to keep an eye on. Genebanks and breeding to the rescue?
- It’s behind a Times of India paywall, alas, but this seems to be an article about the effects of a very warm February on wheat, vegetables and grapes in that country.
- Spring is coming to the northern hemisphere, so of course The New Yorker has a piece on the allure of seed catalogues. I hope there are drought-tolerant and heat-resistant varieties in there. And that they’re clearly labelled as such.
- Meanwhile, oblivious of it all, AramcoWorld has an elegiac piece on the revival of the Karabakh horse in Azerbaijan. Beautiful plumage.
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.
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.
Brainfood: Zea, Urochloa, Medicago, Solanum, Juglans, Camellia, Artocarpus, Lactuca, Phaseolus, and everything else
- Genome sequencing reveals evidence of adaptive variation in the genus Zea. Alleles associated with flowering time were key to adaptation in highland and temperate regions.
- THP9 enhances seed protein content and nitrogen-use efficiency in maize. And it came from wild teosinte.
- Diverged subpopulations in tropical Urochloa (Brachiaria) forage species indicate a role for facultative apomixis and varying ploidy in their population structure and evolution. Polyploidy plus apomixis equals world domination. Maize next?
- Plastid phylogenomics uncovers multiple species in Medicago truncatula (Fabaceae) germplasm accessions. Genebanks need to go beyond conventional taxonomy sometimes.
- Comparative Analysis of the Genetic Diversity of Chilean Cultivated Potato Based on a Molecular Study of Authentic Herbarium Specimens and Present-Day Gene Bank Accessions. Native Chilean potato landraces are being replaced and polluted…
- Diversity of Late Blight Resistance Genes in the VIR Potato Collection. …and will probably continue to be replaced and polluted.
- The United States Potato Genebank Holding of cv. Desiree is a Somatic Mutant of cv. Urgenta. Shit happens, even in well-run genebanks.
- Domestication and selection footprints in Persian walnuts (Juglans regia). Breeding hasn’t had much of an effect on diversity.
- Comparative phylogenetic analysis of oolong tea (Phoenix Dancong tea) using complete chloroplast genome sequences. Oolong teas are a genetic thing.
- Linking breadfruit cultivar names across the globe connects histories after 230 years of separation. Because of genebanks, botanic gardens, herbaria and three generations of women scientists we now know which breadfruit varieties Captain Bligh introduced to the West Indies.
- Lactuca georgica Grossh. is a wild species belonging to the secondary lettuce gene pool: additional evidence, obtained by KASP genotyping. A wild species gets demoted.
- Large genomic introgression blocks of Phaseolus parvifolius Freytag bean into the common bean enhance the crossability between tepary and common beans. A wild species helps with crossing two cultivated species. Figure out which genepool it belongs to after that.
- Genebanking plant genetic resources in the postgenomic era. Yeah, but all the above leads to the question: “what happens when all crop diversity has been sequenced?” Read this to find out.

- ILRI policy brief on how pastoral systems can usefully diversify.

- Local Oregon paper visits the USDA genebank in Pullman.
- It’s the turn of the Native Seed/SEARCH genebank to feature in the news.

- Brits told to grow more faba beans and use them to make bread. Census takers not available for comment.
- Fascinating project on the history of saffron cultivation in eastern England. Now that would spice up all that faba bean bread.
- The Kenosha Potato Project deconstructed to within an inch of its life by Modern Farmer. We’ve blogged about this innovative breeding project here before, have a look. Ah no, I just have, and in fact we haven’t, though we have blogged about William Whitson, an independent tuber breeder, who is however a long-time member of KPP.
- Meanwhile, in Peru, local potato landraces are finding a new market via chips/crisps. Pretty sure we’ve blogged about this too. We are so on the ball.
- Gene editing for conservation? Yes, why not? But nothing on crop and livestock species in this succinct explainer, alas.
