- 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.

- Linking biodiversity into national economic accounting. Yikes, biodiversity makes no contribution to agricultural development at all?
- High sink strength prevents photosynthetic down-regulation in cassava grown at elevated CO2 concentration. Could result in higher yields, but effect will vary among varieties.
- Discovery of beneficial haplotypes for complex traits in maize landraces. Landrace diversity for early plant development, robustness and growth form that could be useful in Europe made accessible.
- Understanding the classics: the unifying concepts of transgressive segregation, inbreeding depression and heterosis and their central relevance for crop breeding. It’s the dispersion of favorable alleles between parents.
- Challenges and Prospects for the Conservation of Crop Genetic Resources in Field Genebanks, in In Vitro Collections and/or in Liquid Nitrogen. Everything that can be in cryo should be in cryo, and some things that currently can’t too.

- 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.

- 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.

- 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.
