- Status and future of seed conservation of threatened plants in the post-2020 era. 21% of threatened plants are conserved in genebanks across 44 countries in Europe and western Asia. Not bad, but not good enough. I wonder how many of those 21% will be of interest to breeders?
- How the international treaty on plant genetic resources for food and agriculture can support effective germplasm exchange: four Colombian case studies. The Plant Treaty can really help a country’s genebanks and breeders drive agricultural development, given half a chance.
- Reconciliation or re-colonization? Critical perspectives on seed banking and colonialism. Indigenous communities need to be careful in collaborating with genebanks and breeders.
- Impacts of climate change on fonio millet: seed germination ecology and suitability modelling of an indigenous West African cereal. Climate change will screw up the germination of fonio in some places, so genebanks and breeders better get cracking.
- Euterpe edulis seed recalcitrance: difficult, yes, but not impossible to genebank. Tricky seed storage behaviour need not deter genebankers.
- Accelerated aging caused diversity and specificity loss in the bacterial communities of Brassica napus seedlings. Genebanks should be careful with their seed aging experiments, because they might screw up the seed microbiome.
- Understanding Biotic Constraints to Taro (Colocasia esculenta) Production in the Derived Savanna and Humid Forest Agroecosystems of Nigeria. Genebanks need seed systems though.

- Domesticated: How Cultivated Species Altered Ancient Silk Road Societies. Different stages of adopting and intensifying the use of domesticates (livestock, horses, and later crops) reshaped economies, mobility, and social organization in north-central Asia, ultimately enabling the emergence of the Silk Road. So domesticated species were as active drivers of Eurasian historical development as of prehistory.
- Ancient grains illuminate the mosaic origin of domesticated wheat. Domesticated wheat arose through repeated hybridizations between distinct wild populations carrying complementary non-shattering spike mutations, followed by ongoing gene flow and regional adaptation, making domestication a prolonged and interconnected process. Long before the result got to the Silk Road.
- A single hybrid origin of cultivated peanut. Domestication of the peanut seems to have been easier than that of wheat.
- A synthetic eco-evolutionary proposal for the conservation of wild relatives of the olive tree. If we ever have to re-domesticate the olive, we should make sure these 53 wild populations are conserved.
- Westward expansion of pearl millet agriculture into the Lac de Guiers basin, Senegal, by c. AD 200. I wonder what the Sahelian equivalent of the Silk Road was.
- Horticultural intensification and plant-based diets of 18th century CE Waikato Māori in Aotearoa New Zealand. At least some Maori ate predominantly sweet potato and taro during the Traditional Period. Which of course were brought to Aotearoa via the ara moana, which, stretching a point, is the South Pacific equivalent of the Silk Road.
- Increase in wild animal consumption across Central Africa. Yeah, but who needs domesticated species anyway.
- Fermentation as food pedagogy: insights into how teaching fermentation facilitates engagement with the food system. Are fermentation microbes domesticated?
Brainfood: Clonal crops edition
- Ancient DNA reveals 4000 years of grapevine diversity, viticulture and clonal propagation in France. Vegetative propagation of grapevines has been going on since the Iron Age.
- High-throughput olive germplasm classification using morphological phenotyping and machine learning. Olive may be generally vegetatively propagated, but you still have to characterize the fruits.
- Varietal Diversity Analysis of Date Palm and Identification of High Agro-Economic Genotypes in Middle Draa. About half of of the date palms in the middle Draa of Morocco are actually from seed. That makes their diversity difficult to conserve.
- Genebank tools for efficient management of viral infections in tropical clonal crops. All those clonal crops need to be kept clean in genebanks. Here’s how.
- Genome degradation in plant tissue culture. All those clonal crops also need to be kept genetically stable in genebanks, and it can be tricky.
Brainfood: Animal diversity edition
- Livestock grazing boosts plant diversity in the Greater Serengeti–Mara Ecosystem. Livestock can be good for biodiversity conservation. But can its diversity be conserved too? Let’s see.
- Conservation and Management of Animal Genetic Resources in the Context of African Livestock Production Systems: The Case for In Situ and Ex Situ Conservation. “The multi-stakeholder breeders-researchers-decision-makers approach remains the most robust solution for sound management and preservation of biological units.” What, no farmers and local communities? No, that’s unfair: community-based conservation is discussed. But it doesn’t feel as central to the whole thing as it should be, somehow.
- Genetic Diversity, Adaptation, Wild Introgression, and Coat Color Mutation of Golden Yak. After all, local communities have maintained the golden yak reasonably well.
- Caprine dairy exploitation on the Iranian Plateau from the seventh millennium BC. Not to mention goats in Iran, and for thousands of years…
- Old goats: 3,000 years of genetic connectivity of the domestic goat in Ireland. …and in Ireland, though for not quite as long, admittedly.
- Dogs were widely distributed across western Eurasia during the Palaeolithic. And local communities have been managing dog populations since way before farming even.
- The dispersal of domestic cats from North Africa to Europe around 2000 years ago. Also, local communities managed early cats separately in the Levant and Egypt. Much later than dogs, but that’s cats for you.
- A microbiome catalog of Chinese traditional artisanal cheeses provides insights into functional and microbial diversity. And don’t forget to conserve the associated microbiome too. I wonder what golden yak cheese is like.
Brainfood: Diversification edition
- Agrobiodiversity for Climate Resilience: A Systematic Review of Yield Stability, Pest Regulation, and Nutrition Outcomes. “…agrobiodiversity emerges as a no-regrets adaptation strategy that strengthens resilience, sustains productivity, and supports nutrition, while creating co-benefits for ecosystems and livelihoods.”
- Global impacts of increased undervalued crop production on environmental, economic, and nutrient outcomes. It’s even good for emissions. No regrets indeed. But who’s going to do drive all this diversification?
- Impact of a homegardening intervention on crop diversity: results from a cluster-randomized trial in Bangladesh. Homegardeners maybe?
- National genebanks as agents of change for supporting farmers’ crop diversification. Oh, I know who else can help.
- Expanding the genetic diversity of chickpeas from the Ukrainian genebank to new agricultural systems. Even in a war zone.
- The genetic landscape of Pacific taro: diversity, population structure, and strategic germplasm management. Even in paradise.
- Influences of territorial conflicts on local crop diversity in a campesino community in the Colombian Caribbean. Because war is bad for agrobiodiversity. No word on the effect of paradise.
- Reviewing assumptions around the giant maize Jala landrace locally known as maíz de húmedo: the importance of local knowledge for the in situ conservation of agrobiodiversity. On top of everything, agrobiodiversity can even be iconic.
