- A systematic review of conservation efforts using non-monetary, non-regulatory incentives to promote voluntary behaviour change. Mix it up, and get personal.
- Chromosome reciprocal translocations have accompanied subspecies evolution in bananas. Some subspecies of M. acuminata were more involved in cultivar development than others.
- 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, should be in cryo.
- Population genetic structure and classification of cultivated and wild pea (Pisum sp.) based on morphological traits and SSR markers. The species are real, the subspecies maybe less so.
- Iron Absorption from Iron-Biofortified Sweetpotato Is Higher Than Regular Sweetpotato in Malawian Women while Iron Absorption from Regular and Iron-Biofortified Potatoes Is High in Peruvian Women. More than just calories.
- Survey data on income, food security, and dietary behavior among women and children from households of differing socio-economic status in urban and peri-urban areas of Nairobi, Kenya. Lots of data to play around with, including on dietary diversity. But not on biofortification, I don’t think.
- “Rambo root” to the rescue: How a simple, low‐cost solution can lead to multiple sustainable development gains. Grow it on degraded land. After biofortifying it, natch.
- Genetic Diversity and Structure of Iberoamerican Livestock Breeds. Creole breeds are hanging in there, especially in marginal areas. Maybe they could be fed on cassava?
- Whole genome analysis of water buffalo and global cattle breeds highlights convergent signatures of domestication. The same mutations occurred independently and were then selected for in water buffalo and cattle.
- Bison, anthropogenic fire, and the origins of agriculture in eastern North America. Bison favoured the growth of crop wild relatives in the prairies. No word on any attempt to domesticate the brutes, but the above should provide some guidance.
- Archaeogenomics of a ~2,100-year-old Egyptian leaf provides a new timestamp on date palm domestication. Dates showed introgression from wild relatives way back. No evidence of bison involvement.

- Viewpoint: COVID-19 and seed security response now and beyond. Think before you spread seeds around.
- Integrated crop-livestock system with system fertilization approach improves food production and resource-use efficiency in agricultural lands. Integrating livestock in soybean production is good for the amount of energy produced per unit of nutrient applied, if that’s what floats your boat.
- Holistic agricultural diversity index as a measure of agricultural diversity: A cross-sectional study of smallholder farmers in Lilongwe district of Malawi. An interesting way of measuring overall farm diversity. But is there a link with dietary diversity?
- Dietary diversity scores, nutrient intakes and biomarkers vitamin B12, folate and Hb in rural youth from the Pune Maternal Nutrition Study. Dietary diversity is linked to better micronutrient status. But is there a link with genetic diversity?
- Evaluating surrogates of genetic diversity for conservation planning. There’s nothing quite as good as neutral markers, alas.
- Phenotypic diversity assessment within a major ex situ collection of wild endemic coffees in Madagascar. Never mind the species or genetic diversity, look at the trait variability.
- Understanding cassava varietal preferences through pairwise ranking of gari‐eba and fufu prepared by local farmer–processors. Landraces are sometimes better than improved varieties.
- Do the importations of crop products affect the genetic diversity from landraces? A study case in garlic (Allium sativum L.). Apparently not, surprisingly enough.
- Overcoming barriers to the registration of new varieties. DUS needs genomics. But what about registering landraces? Do we need a completely separate system for that?
- Legal geographies of kava, kastom and indigenous knowledge: Next steps under the Nagoya Protocol. One approach implementing Nagoya at the community level. But is it scalable?
- New evidence on the earliest domesticated animals and possible small-scale husbandry in Atlantic NW Europe. There was a long period of contact between local hunter-gatherers and incoming farmers, resulting in a transitional farmer-herder stage.

- 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.

- Does it matter who advises farmers? Pest management choices with public and private extension. Yes, at least in Switzerland. Public = prevention, private = cure. Well colour me surprised.
- Ethiopia’s transforming wheat landscape: tracking variety use through DNA fingerprinting. Only 28% of farmers correctly named their wheat varieties, many of which were from CGIAR breeding programmes.
- Analysis of the Similarity between in Silico Ideotypes and Phenotypic Profiles to Support Cultivar Recommendation—A Case Study on Phaseolus vulgaris L. Italian farmers not great at keeping track of new varieties either, but who needs names when you have fancy maths?
- Morphological, Sensorial and Chemical Characterization of Chilli Peppers (Capsicum spp.) from the CATIE Genebank. From 192 accessions to this little beauty from Panama.
- Two divergent chloroplast genome sequence clades captured in the domesticated rice gene pool may have significance for rice production. Rice is from Mars, rice is from two Venuses.
- Identification of Mung Bean in a Smallholder Farming Setting of Coastal South Asia Using Manned Aircraft Photography and Sentinel-2 Images. From 10-m imagery for pity’s sake! Amazing stuff. Soon we’ll be able to distinguish landraces from modern varieties, right? Right?
- 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.
