- 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.
Nibbles: Avocado development, Marketing seeds, Saving seeds, Lettuce DNA
- Avocado value chain gets it together. Hope some money flows back to the genebank.
- Indian women fall back on vegetable seeds.
- A seed saving network takes root in Kenya.
- CGN teams up with BGI to sequence its lettuce collection.
Brainfood: Diversification, Annona, Banana genebank, Sustainable livestock, One Health, Polyploidy, Breeding pipeline, Evolutionary breeding, Seed storage, European landraces, Governance, Virgin oil, Cereal nutrition, Spinach origins, Botany apps
- Agricultural diversification promotes multiple ecosystem services without compromising yield. Meta-meta-analysis shows diversification is good for biodiversity, pollination, pest control, nutrient cycling, soil fertility, and water regulation and not bad for crop yields either.
- Holocene land and sea‐trade routes explain complex patterns of pre‐Columbian crop dispersion. Cherimoya reached the Andes by boat.
- Safeguarding and using global banana diversity: a holistic approach. 1617 banana accessions from 38 countries maintained in an in vitro collection, backed-up in cryo; over 18,000 samples distributed to researchers and farmers in 113 countries in 35 years. And that’s just the basics.
- Designing sustainable pathways for the livestock sector: the example of Atsbi, Ethiopia and Bama, Burkina Faso. It’s not just a straight choice between intensive or extensive production, stop with the dichotomies.
- Moving health to the heart of agri-food policies; mitigating risk from our food systems. It’s difficult to separate food from health; and yet…
- Genes derived from ancient polyploidy have higher genetic diversity and are associated with domestication in Brassica rapa. Agriculture depends on polyploidy.
- Genetic diversity is indispensable for plant breeding to improve crops. Plant breeding from an industry perspective, using the Brassicaceae as a case study.
- Yield, yield stability and farmers’ preferences of evolutionary populations of bread wheat: A dynamic solution to climate change. A totally different perspective to the above, using a totally different crop. Compare and contrast.
- Enhancing seed conservation in rural communities of Guatemala by implementing the dry chain concept. Cool way for farmers to save their seeds so they can do the above.
- Landrace hotspots identification in Europe. Where to implement the above.
- Innovation and the commons: lessons from the governance of genetic resources in potato breeding. This is a tricky one. Near as I can figure it, the authors are trying to say that it’s difficult to govern genetic resources apart from the tools needed to develop and use them. But hey, you have a go.
- Conservation of Native Wild Ivory-White Olives from the MEDES Islands Natural Reserve to Maintain Virgin Olive Oil Diversity. I did not have an endemic insular wild albino olive on my bingo card.
- Agri-nutrition research: Revisiting the contribution of maize and wheat to human nutrition and health. Staple cereals are more nutritious than often thought.
- On the origin and dispersal of cultivated spinach (Spinacia oleracea L.). Spinach originated more eastward than often thought.
- What plant is that? Tests of automated image recognition apps for plant identification on plants from the British flora. Botanists shouldn’t give up their day jobs.
Nibbles: CePaCT job, Banks, Business, Food System 2030, AnGR book
- Very cool genebank job going in Fiji.
- Banks should do more to support genebanks…
- …because it makes business sense.
- The German government is on board with Food System 2030.
- Nice book on the history of conservation of heritage livestock breeds.
A bean thread for the ages
Since I’m on a Twitter thread kick, get a load of this mega-thread on beans from Jorge Berny.
Beans are getting popular and they have helped me endure grad school. I´ll post some of my favorites while this pandemic endures.
Tzama´ are mostly grown in Southern Mexico, Belize and Guatemala. Planted later, as a relay after maize, with a shorthish cycle. Tasty AF. pic.twitter.com/OqAnRedHk7

Here’s the ThreadReader version for those of you who are averse to Twitter. Epic.
And, you can even wear them.
