- Resistance and Tolerance to Root Herbivory in Maize Were Mediated by Domestication, Spread, and Breeding. Domestication and spread decreased maize resistance to Western corn rootworm, but breeding increased it.
- Does genetic diversity protect host populations from parasites? A meta‐analysis across natural and agricultural systems. Yes, but it depends. Western corn rootworm unavailable for comment.
- Genome of Solanum pimpinellifolium provides insights into structural variants during tomato breeding. Lots of variants in regulatory genes for agronomic traits, compared to domesticated lines.
- Genomic evidence for recurrent genetic admixture during the domestication of Mediterranean olive trees (Olea europaea L.). There was a domestication bottleneck back in the day, but that was almost wiped out by later repeated introgression from the wild relative as the crop spread. So quite different from the above maize and tomato cases?
- Multi-parent populations in crops: a toolbox integrating genomics and genetic mapping with breeding. Not just good for QTL mapping any more, but you need a whole package of stuff for them to be useful to breeding programmes.
- Current uses of Andean Roots and Tuber Crops in South American gourmet restaurants. None of the chefs interviewed knew of mauka, but it’s not their fault.
- Payments for agrobiodiversity conservation services: An overview of Latin American experiences, lessons learned and upscaling challenges. Conserving in situ 100 varieties on 5 hectares each would cost US$70,000 p.a. Maybe useful for mauka? But will chefs pay?
- Genetic and agro-morphological diversity in global barley (Hordeum vulgare L.) collection at ICARDA. Under heat stress, though, which is the important bit left out of the title. Unclear if any of the material was from the Canaries (see below), but I can find out if anyone’s interested. Come to think of it, I’m kinda interested myself…
- An Evolutionary Approach to the History of Barley (Hordeum vulgare) Cultivation in the Canary Islands. You can apparently infer historical extents of cultivation on different islands in the archipelago, as well as the timing of separation of populations, which is pretty amazing. No word on representation in rock art though (see below).
- Enset (Ensete ventricosum) and the Archaeology of Southwestern Ethiopia. Information comes mainly from megalithic and rock art sites, which is pretty amazing. No word on genetic relationships, at least in this paper. Do you need me to link to previous Brainfoods on enset? No, of course you don’t, you know how to search the archive. You just put your lips together, and
whistleblow (kudos to whoever quotes the reference in the comments first). - Relict Plant Communities at Prehispanic Sites in Oaxaca, Mexico: Historical Implications. Ancient native Mexicans really liked succulents around their settlements. Well, who wouldn’t, when all is said and done?
- To clean or not to clean: Cleaning open‐source data improves extinction risk assessments for threatened plant species. Clean. Always clean. And then clean again.
- Global Patterns and Drivers of Bee Distribution. Hope they cleaned the data or this unusual double-humped diversity pattern could be in trouble, and that would be a pity.

- 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.

- The development of the international center model for agricultural research: A prehistory of the CGIAR. The model didn’t start with those canonical US foundations, and owes more than a little to colonialism. Further integration is needed.
- Document or Lose It—On the Importance of Information Management for Genetic Resources Conservation in Genebanks. Standardization, openness and interoperability. Easier said than done, but if you’re looking for further integration…
- AI-powered banana diseases and pest detection. But can it tell bananas from plantains? Nice to link it up with the above.
- Crop Wild Relatives as Germplasm Resource for Cultivar Improvement in Mint (Mentha L.). 450 clones representing 34 taxa maintained by USDA. The next 2 are USDA things too.
- Germplasm Development of Underutilized Temperate U.S. Tree Crops. Sure, introduce species from abroad, but if they have local wild relatives you have another route to adaptation. Take the hazelnut, for example…
- Subspecies Variation of Daucus carota Coastal (“Gummifer”) Morphotypes (Apiaceae) Using Genotyping-by-Sequencing. One morphology and niche, 5 genetic groups.
- Comparisons of sampling methods for assessing intra- and inter-accession genetic diversity in three rice species using genotyping by sequencing. Some differences in results among sampling methods, but not huge.
- Combining ability analysis on rhizomatousness via incomplete diallel crosses between perennial wild relative of rice and Asian cultivated rice. If you want perennial cultivated(ish) rice, you have to pick your parents carefully.
- Something old, something new: Evolution of Colombian weedy rice (Oryza spp.) through de novo de‐domestication, exotic gene flow, and hybridization. Weedy rice is just local domesticated rice gone bad, at least in Colombia. Gosh I hope that perennial rice doesn’t get de-domesticated.
- It’s not just poverty: unregulated global market and bad governance explain unceasing deforestation in Western Madagascar. Stop blaming subsistence slash-and-burn.
- Climate change enforces to look beyond the plant – the example of pollinators. Create nice conditions for pollinators on farms, it’ll be worth it.
- Paternal Origins and Migratory Episodes of Domestic Sheep. 4 parental lineages, one with primitive features and another with fat tails.
