- New technologies to improve the ex situ conservation of plant genetic resources. Genebanks need to catch up with the latest science even just to maintain their seeds.
- Advanced Strategic Research to Promote the Use of Rice Genetic Resources. High-throughput phenotyping and genome sequencing are the latest science that will make the most of those seeds.
- Phased diploid genome assemblies and pan-genomes provide insights into the genetic history of apple domestication. Analysis of genomes of two main wild progenitors plus the crop uncovers genes so far untapped for improvement.
- The elephant grass (Cenchrus purpureus) genome provides insights into anthocyanidin accumulation and fast growth. It’s related to pearl millet, apparently. Which may or may not be a good thing. No word on any genes so far untapped for improvement.
- Triticum population sequencing provides insights into wheat adaptation. Wide adaptation is largely due to introgression from the wild. No word on any genes so far untapped for improvement.
- The Right Tortilla for the Right Occasion: Variation in Consumers’ Willingness to Pay for Blue Maize Tortillas Based on Utilization. Consumers are willing to pay 42% more for blue tortillas, but only when eating out, presumably as part of virtue signalling.
- 30 years of free‐air carbon dioxide enrichment (FACE): What have we learned about future crop productivity and its potential for adaptation? That enrichment wont save us, that’s what.
- Phenotypic Divergence Analysis in Pigeonpea [Cajanus cajan (L.) Millspaugh] Germplasm Accessions. From 81 accessions to 9 promising ones, at least for Malawi.
- A model for the domestication of Panicum miliaceum (common, proso or broomcorn millet) in China. Domestication took 3000 years.
- Origins and genetic legacy of prehistoric dogs. All dogs are descendants of a now extinct wolf population, and their genetics show both interesting parallels with, and divergences from, that of humans.
- Brain Size Does Not Rescue Domestication Syndrome. Not even for humans, I suspect. Kidding apart, this is fascinating. It suggests that, for animals at least, the domestication syndrome is not actually a thing. Or at least has not been properly tested. If there’s interest, I’ll do a full post. Let me know in the comments below.
- Ancient genomes reveal tropical bovid species in the Tibetan Plateau contributed to the prevalence of hunting game until the late Neolithic. The now tropical gaur ranged much further north during the warmer Neolithic, which facilitated the exploration of the Tibetan Plateau.
- Optimization of in vitro germination and cryopreservation conditions for preserving date palm pollen in the USDA National Plant Germplasm System. Always good to have another way of storing germplasm.
- Beyond the material: knowledge aspects in seed commoning. Comparing global with local seed commons reveals importance of managing knowledge, both scientific and traditional.
- Genetics to the rescue: managing forests sustainably in a changing world. To manage forests sustainably, you have to conserve and use their genetic diversity. Interesting that they needed a conference to work that out.
- Genetic mixing for population management: from genetic rescue to provenancing. And using that genetic diversity could mean mixing it up.
- The importance of genomic variation for biodiversity, ecosystems and people. Maintaining ecosystem services means maintaining genetic diversity. Sounds like these authors went to the same conference.
Yes, we have lots of banana news
There’s recently been some interesting banana germplasm collecting in Papua New Guinea. ((No, I don’t mean the Bougainville expedition, do keep up.))
The results are summarized in two articles, one in Plants evaluating methods to ensure the viability of collected seeds, and the other in Crop Science summarizing the characterization of diverse phenotypes.
We’ve included both the papers in question in past Brainfoods, but this press release, from which the above quote is taken, does a really nice job of bringing them together. It might also have added an additional recent paper on the work of the International Musa Germplasm Transit Centre (ITC), but anyway.
There’s a whole bunch of summary statistics on the ITC, and lots of useful links, on the Genebank Platform webpage. And of course Genesys has a selection of accession-level data. But the place for all your banana information needs is ProMusa.
Brainfood: Now what edition
- Image-Based Goat Breed Identification and Localization Using Deep Learning. Fancy maths can identify goat breeds from photos. Ok, cool, now what?
- AI Naturalists Might Hold the Key to Unlocking Biodiversity Data in Social Media Imagery. Fancy math can often identify common flowers on Flickr. Ok, cool, now what?
- FoodMine: Exploring Food Contents in Scientific Literature. Fancy maths can trawl the literature to pick out the chemical components of different foods. Ok, cool, I guess, now what?
- Cultural and linguistic diversities are underappreciated pillars of biodiversity. Well, yeah. But now what?
- Global priority areas for ecosystem restoration. Fancy maths says restoring 15% of converted lands in identified priority areas could avoid 60% of expected extinctions while sequestering 30% of the total CO2 increase in the atmosphere since the Industrial Revolution. Cool, now what?
- An unexpectedly large count of trees in the West African Sahara and Sahel. Wait, does that mean some of the above won’t be necessary?
- Cost and affordability of nutritious diets at retail prices: Evidence from 177 countries. Fancy maths shows that nutritious diets are almost 3 times as expensive as diets supplying basic energy needs, and costs increase with remoteness. Ok, cool, now what?
- Phylogenetic inference enables reconstruction of a long-overlooked outbreak of almond leaf scorch disease (Xylella fastidiosa) in Europe. The olive plague started on almonds. Ok, now what though?
- Genome-wide association study in accessions of the mini-core collection of mungbean (Vigna radiata) from the World Vegetable Gene Bank (Taiwan). Genotyping, phenotyping and fancy maths find that mungbean could grow in temperate conditions. Ok, cool, now what?
- Enhancing the searchability, breeding utility, and efficient management of germplasm accessions in the USDA−ARS rice collection. Genotyping and fancy maths can improve genebank management. Well, yeah, but now what? No, wait, we know exactly now what: digital genebanks!
- Ok, that was a bit of fun, but the important point is that research, no matter how cool, is only the beginning.
Brainfood: CGIAR genebanks, Sweet potato heat, Rice breeding, CWR gap trifecta, PES, Wild potatoes, Wild olives, Rare olives, Cryo veggies, Broccoli diversity, Crop switching, Cattle diversity, IK
- Germplasm Acquisition and Distribution by CGIAR Genebanks. A lot of stuff going in, a lot of stuff coming out, to everyone’s benefit. 35 years of data, with special focus on the last 10.
- Intraspecific diversity as a reservoir for heat-stress tolerance in sweet potato. 132 out of 1973 accessions tolerant of heat, though in different ways. A prime example of the above benefits.
- Identification and characterization of high‐yielding, short‐duration rice genotypes for tropical Asia. Short-duration varieties will need to be a bit taller and leafier to yield more. Another example of the above benefits.
- Modelled distributions and conservation priorities of wild sorghums (Sorghum Moench). More stuff needs to go into the above genebanks, though, for example from N. Australia.
- Ex situ and in situ conservation gap analysis of crop wild relative diversity in the Fertile Crescent of the Middle East. Same from the Fertile Crescent.
- In situ and ex situ conservation gap analyses of crop wild relatives from Malawi. And not just the above genebanks either.
- The Potential of Payment for Ecosystem Services for Crop Wild Relative Conservation. Ok, we have the gaps (see above), and now here we have the method. What’s stopping us?
- Assessing under-Estimation of Genetic Diversity within Wild Potato (Solanum) Species Populations. Wild diploid species more diverse than previously thought. So providing more ecosystem services?
- Genetic diversity and differentiation of Olea europaea subsp. cuspidata (Wall. & G.Don) Cif. in the Hajar Mountains of Oman. No word on the ecosystem services being provided.
- The investigation of minor and rare Tunisian olive cultivars to enrich and diversify the olive genetic resources of the country. Rare + minor doesn’t mean bad. But maybe an influx of Omani genes would help?
- Biobanking of vegetable genetic resources by in vitro conservation and cryopreservation. Yes, even for vegetables.
- From landrace to modern hybrid broccoli: the genomic and morphological domestication syndrome within a diverse B. oleracea collection. Four subpopulations: Calabrese broccoli landraces, hybrids, sprouting broccoli, and violet cauliflower. Diversity in modern varieties decreasing with time.
- Crop switching reduces agricultural losses from climate change in the United States by half under RCP 8.5. But it will have to be a lot of switching. Hopefully out of broccoli.
- The mosaic genome of indigenous African cattle as a unique genetic resource for African pastoralism. An influx of zebu genes about a thousand years ago is responsible for the success of African pastoralism.
- Protection of traditional agricultural knowledge and rethinking agricultural research from farmers’ perspective: A case from Turkey. Against power imbalances the gods themselves contend in vain.
Nibbles: Crop loss, Soil data, CONABIO stuff, Digging dope, Ceres2030
- There’s a series of interactive workshops to gather feedback on how to measure the Global Burden of Crop Loss. I want an initiative on the Global Burden of Crop Diversity Loss though.
- Soil data makes its way to Google Maps.
- CONABIO has some really excellent agrobiodiversity posters and other resources. Calabazas and amaranth are just the start, so dig away on these orphan crops and others.
- Speaking of digging, ancient people got high. Well there’s a shocker.
- Speaking of shockers: huge literature review says researchers should get to grips with smallholders.
