Nibbles: Yunnan mushrooms, Torres Is bananas, Boxgrove, Gluten trends, Apple rootstocks, USDA horticulture job
- There’s a sort of mycological culinary hotspot in Yunnan… Yeah, I thought that too.
- Signs found of old banana cultivation in Australia. Well, kinda. As in not as old as in PNG, and not mainland Australia.
- Really, really old horse butchery site in southern England excavated. When the Brits ate horses. Well, kinda.
- New wheat is pretty much like old wheat, gluten-wise at least.
- Breeding better apple rootstocks at USDA. A hitherto somewhat neglected aspect of apple genetic conservation and improvement.
- Speaking of USDA, here’s another job.
Meta-Brainfood for the weekend
Time to clean up a few things, I think. For a while now, I’ve been hoarding links to edited volumes. My idea was to do a special dedicated Brainfood on each one, but I now fear that just ain’t gonna happen. Too much other stuff on. So here they are. Maybe one of you will help me out? You know what to do. A pithy one or two sentences summarizing each paper, based on the abstract only if you’re into the whole brevity thing. Interested? Let me know in the comments below, and we’ll set something up. Our first guest-curated Brainfood…
Here they are:
- Do you remember the 2017 book Against The Grain: A Deep History of the Earliest States by James C. Scott? I think we may have blogged about it. Anyway, it suggested that it was grain (as opposed to tuber) cultivation that led to the development of hierarchical states. Grain is visible and portable, and so easy to tax, you see. There are interviews with the author galore if you like podcasts. Ok, well, the Cambridge Archaeological Journal had a whole Review Symposium deconstructing that particular revisionist narrative.
- In 2018, something called the 1st International Conference on Genetic Resources and Biotechnology was held in Bogor, Indonesia. A bit of a misnomer, it was really mainly about “[i]nformation system and exchanges of genetic resources for effective crop improvement.” These are the proceedings, and all of the dozens of papers are open access. Maybe someone out there could do their Top 10.
- This one is not as relevant as the others, but it’s interesting nonetheless: Remote Sensing of Plant Biodiversity. Surely some of the 20 contributions have something to say about agricultural biodiversity? Who’s willing to have a look?
- Then there’s the Special Issue of Application in Plant Sciences on Machine Learning in Plant Biology: Advances Using Herbarium Specimen Images. Yummy. Automated identification of CWR specimens, anyone?
- And finally, just out, a Topical Collection in Agriculture and Human Values on Agriculture, Food & Covid-19. Come on, who can resist a hot-take (well, a Rapid Response Opinion) entitled Maybe there is an alternative after all?
Looking forward to hearing from you.
And don’t worry, there’ll be a normal Brainfood on Monday as usual.
Brainfood: Perennial favourites, Feral grapevines, Silky cat, Damaged yams, Maize vs sorghum, Sunflower ecotypes, Fungal diversity, Pacific voyaging, Vitamin seeds, Biogeoinformatics, Natural language, Evaluation, Aquaculture
- Perennial vegetables: A neglected resource for biodiversity, carbon sequestration, and nutrition. Over 600 perennial veggies on 6% of global vegetable cropland.
- Genomic Evidences Support an Independent History of Grapevine Domestication in the Levant. Separate from what happened in the Caucasus, that is.
- Distribution, prevalence and severity of damages caused by nematodes on yam (Dioscorea rotundata) in Nigeria. A quarter of tubers and half of heaps showed nematode symptoms.
- Maize long-term genetic progress explains current dominance over sorghum in Argentina. Follow the money.
- Phenotypic and physiological responses to salt exposure in Sorghum reveal diversity among domesticated landraces. Salinity tolerance was acquired early but then lost in some geographic regions where it wasn’t needed. See what happens when you invest in a crop?
- Massive haplotypes underlie ecotypic differentiation in sunflowers. It’s the recombination-suppressing inversions, stupid.
- GlobalFungi, a global database of fungal occurrences from high-throughput-sequencing metabarcoding studies. Cool. Do landraces of a crop next.
- The earliest domestic cat on the Silk Road. Coincided with rapid urbanization in the 9th century.
- Native American gene flow into Polynesia predating Easter Island settlement. Yeah, but did Americans go west of their own accord or in Polynesian boats? And did they have sweetpotatoes with them? And cats?
- Genetic markers associated with seed longevity and vitamin E in diverse Aus rice varieties. 5 markers on 4 chromosomes.
- Biogeoinformatics for the management of Farm Animal Genetic Resources (FAnGR). Software for monitoring erosion and detecting locally adapted genotypes. Plus preserve traditional practices.
- Computing on Phenotypic Descriptions for Candidate Gene Discovery and Crop Improvement. Casually talk about a plant in the field –> fancy math –> the plant’s genotype.
- Data synthesis for crop variety evaluation. A review. Focus on ranking. Oh, to mash it up with the above.
- Scenarios for Global Aquaculture and Its Role in Human Nutrition. For aquaculture to contribute to nutrition it needs enabling trade and economic policies. Well I never.
Brainfood: Bacterial contamination, Yam diversity, Multi-parent pops, Small millets breeding, Plural valuation, Seed conservation, Transition, Wild spuds, Enset conservation, Cassava viruses, Maize stemborer, Rice roots
- Identification and Control of Latent Bacteria in in vitro Cultures of Sweetpotato [Ipomoea batatas (L.) Lam]. 10% of about 2400 in vitro plantlets had a total of about 20 types of bacteria, some of which might be beneficial for all we know, but all of which could be removed.
- Genome-wide genotyping elucidates the geographical diversification and dispersal of the polyploid and clonally propagated yam (Dioscorea alata L.). Asian and Pacific genepools, thence to India, then Africa, then the Caribbean.
- Multi-parent populations in crops: a toolbox integrating genomics and genetic mapping with breeding. Like MAGIC.
- Genetic and genomic resources, and breeding for accelerating improvement of small millets: current status and future interventions. Here’s all the promising material, now go crazy with the MAGIC.
- Plural valuation of nature for equity and sustainability: Insights from the Global South. The road to decolonizing conservation.
- Long-Term Storage and Longevity of Orthodox Seeds: A Systematic Review. Treat your seeds right.
- Changes in food access by mestizo communities associated with deforestation and agrobiodiversity loss in Ucayali, Peruvian Amazon. Less diversified diets, loss of forest cover and reduced agricultural biodiversity go together, somehow.
- Evaluation of Wild Potato Germplasm for Tuber Starch Content and Nitrogen Utilization Efficiency. Wild species are better on both counts.
- Conservation protocols for Ensete glaucum, a crop wild relative of banana, using plant tissue culture and cryopreservation techniques on seeds and zygotic embryos. 2 accessions thus conserved at NBPGR.
- Computational models to improve surveillance for cassava brown streak disease and minimize yield loss. Fancy maths shows that planting clean material helps a lot.
- Genome wide association analysis of a stemborer egg induced “call-for-help” defence trait in maize. “…egg-induced parasitoid attraction trait was more common in landraces than in improved inbred lines and hybrids.”
- Low Additive Genetic Variation in a Trait Under Selection in Domesticated Rice. That would be root growth under drought and Al stress conditions. Every accession has a different set of low frequency causal alleles.
