- Conservation needs to break free from global priority mapping. Couldn’t agree more. And less.
- National climate and biodiversity strategies are hamstrung by a lack of maps. Wait, what?
- The evolutionary genomics of species’ responses to climate change. You need to combine niche modelling with genetic adaptation to get the best maps.
- Payoffs to a half century of CGIAR research. A benefit-to-cost ratio (BCR) of 10:1. Not counting the genebanks. And all the maps.
- A case for conserving plant pathogens. But will it be worth it?
- Poor data stewardship will hinder global genetic diversity surveillance. What’s the BCR for decent metadata?
- Mitigating tradeoffs in plant breeding. Cutting out the cross-talk changes tradeoff to payoff.
- Comparing Productivity of Organic and Conventional Farming Systems: A Quantitative Review. Conventional is more productive. But should yield be the only criterion?
- Priority micronutrient density in foods. Right. Micronutrients are also important.
- Reconciling yield gains in agronomic trials with returns under African smallholder conditions. And how was yield measured anyway?
- Data-driven, participatory characterization of traditional farmer varieties discloses teff (Eragrostis tef) adaptive and breeding potential under current and future climates. This might well be an example of applying the lessons of the above.
- Genetic Diversity and Utilization of Cultivated Eggplant Germplasm in Varietal Improvement. The wild relatives will save us.
- Quinoa Phenotyping Methodologies: An International Consensus. But will it work for the wild relatives? Just kidding, this is an important development for another crop (with the above) which doesn’t have something like the CGIAR and its 10:1 BCR behind it…
Nibbles: Genebanks in Brazil, Tunisia, Ghana, Ethiopia, Goan rice, Wheat adoption, Peruvian hot peppers & cacao, Amazonian fruits and nuts, Dates, Great Hedge of India, Conservation genetics presentation
- Safety duplicating a chickpea collection.
- Tunisia’s genebank in the news.
- Ghana’s genebank trying to save taro.
- Using a genebank to improve Elephant grass.
- On-farm conservation of rice in Goa.
- Molecular tools show that a couple of varieties account for about half the wheat acreage in Bangladesh and Nepal. Hope all the landraces are in genebanks, and safety duplicated.
- Celebrating Peruvian pepper diversity.
- Peru’s cacao diversity doesn’t need help, apparently.
- However, the Amazon’s wild-extracted fruits (including cacao and a wild relative) could be in trouble. Hope they’re in genebanks, just in case.
- How the date came to the US. Including its genebanks.
- India had a precursor of the Green Wall of Africa but nobody remembers it. Glad it wasn’t used as a genebank of sorts.
- Conservation genetics (i.e., most of the above) explained in 48 slides.

- Extreme climate events increase risk of global food insecurity and adaptation needs. Factoring in climate variability shows that just considering the change in the average climate underestimates the food security hit.
- Increases in extreme heat stress in domesticated livestock species during the twenty-first century. And the hit is already landing.
- Data-driven decentralized breeding increases prediction accuracy in a challenging crop production environment. What we therefore need is 3-D breeding.
- Novel Sources of Pre-Harvest Sprouting Resistance for Japonica Rice Improvement. Including for resistance to pre-harvest sprouting in rice due to unexpected typhoons.
- The genome of stress tolerant crop wild relative Paspalum vaginatum leads to increased biomass productivity in the crop Zea mays. For sure crop wild relatives are going to help.
- Megabase-scale presence-absence variation with Tripsacum origin was under selection during maize domestication and adaptation. If they haven’t helped already.
- Registration of three peanut allotetraploid interspecific hybrids resistant to late leaf spot disease and tomato spotted wilt. Sometimes you need multiple CWR.
- Collection, genotyping and virus elimination of cassava landraces from Tanzania and documentation of farmer knowledge. But landraces too will come in handy, especially if farmers’ knowledge is properly documented.
- Prioritizing host phenotype to understand microbiome heritability in plants. And don’t forget the microbiome.
- Economic analysis of habitat manipulation in Brassica pest management: Wild plant species suppress cabbage webworm. Not to mention the ecosystem as a whole.
- Relevance of hop terroir for beer flavour. Oh hell, I give up, time for a craft beer.
- On the Trail of the German Purity Law: Distinguishing the Metabolic Signatures of Wheat, Corn and Rice in Beer. Maybe even a weissbier.
Brainfood: Diversification, Diverse diet, Urban forests, Local seed systems, Heterosis, Oil palm core, Black Sigatoka resistance, Pearl millet diversity, Alfalfa diversity, Barley evaluation x2, Ganja origins, Apple origins, Millet diversity, Pepper diversity, Grapevine domestication, Vanilla diversity
- A global database of diversified farming effects on biodiversity and yield. Always good to have the data.
- Dietary agrobiodiversity for improved nutrition and health outcomes within a transitioning indigenous Solomon Island food system. Maybe we should have a database of diversified farming effects on health and nutrition too?
- Exploring ‘beyond-food’ opportunities for biocultural conservation in urban forest gardens. Always good to have more trees.
- Community seed network in an era of climate change: dynamics of maize diversity in Yucatán, Mexico. Always good to have landraces. And neighbours.
- Microbe-dependent heterosis in maize. Maize hybrids need microbes.
- Assessment of genetic diversity and population structure of oil palm (Elaeis guineensis Jacq.) field genebank: A step towards molecular-assisted germplasm conservation. 30% seems a lot for a core collection. But it’s good to have the data.
- Sources of resistance to Pseudocercospora fijiensis, the cause of black Sigatoka in banana. 11 resistant accessions out of 95 seems pretty good, on the other hand.
- GWAS unveils features between early- and late-flowering pearl millets. Based on a national-level core collection in Senegal. Presumably this will scale?
- Germplasm Collection, Genetic Resources, and Gene Pools in Alfalfa. Lots of work has been done. More work is needed on the wild relatives though.
- Assessment and modeling using machine learning of resistance to scald (Rhynchosporium commune) in two specific barley genetic resources subsets. Fancy maths helps to identify the barley genebank accessions you really need.
- Strategic malting barley improvement for craft brewers through consumer sensory evaluation of malt and beer. More fancy maths, this time applied to a hedonic data in the service of beer. Germplasm evaluation we can all get behind. No FIGS, alas.
- Large-scale whole-genome resequencing unravels the domestication history of Cannabis sativa. 4 genetic groups: primordial (located in China, not Central Asia, and going back 12,000 years), 2 medicinal, 1 fibre. Now for the hedonic evaluation.
- The Origins of the Apple in Central Asia. Probably domesticated to cope with the munchies.
- Genetic Divergence and Population Structure in Weedy and Cultivated Broomcorn Millets (Panicum miliaceum L.) Revealed by Specific-Locus Amplified Fragment Sequencing (SLAF-Seq). There are interesting genetic differences between wild and feral forms, and between eastern and central-western cultivated forms. The Silk Road trifecta.
- Global range expansion history of pepper (Capsicum spp.) revealed by over 10,000 genebank accessions. Spoke too soon. The Silk Road had a role in pepper movement too. Among other trade routes. Interesting, and unsurprising, that genes for pungency show distinct geographic patterns.
- Genomic evidence supports an independent history of Levantine and Eurasian grapevines. First domestication in the Caucasus, and then in the Levant, but not clear if from local sources. No word on hedonic evaluation.
- Genotyping-By-Sequencing diversity analysis of international Vanilla collections uncovers hidden diversity and enables plant improvement. Belize seems to be a real hotspot. The Silk Road not involved.

- 26 million hectares of forest were lost in 2020.
- Genetic groups in grizzly bears line up with Indigenous languages in British Columbia. How about the trees, though?
- But why weren’t grizzly bears domesticated? Because they’re not friendly, feedable, fecund and family-friendly.
- Drones and wheat breeding.
- Crowdsourcing okra evaluation. No drones involved.
- Health-conscious urban Indians eat millet for health reasons. Goes great with okra.
- The Common Table: sharing stories about reforming the food system. Like a couple of the above.
