- Natufian sickle blades (ca. 15,000–11,700 cal. BP) reveal cereal cultivation ca. 4.5 millennia before domestication. Archaeological evidence from ancient sickle blades suggests that people were harvesting cereal seeds thousands of years before domesticated forms emerged, blurring the line between foraging and farming, and offering fresh insight into the long co-evolution of humans and crops.
- Teosinte alleles enhance nitrogen assimilation and seed protein in maize. Wild relatives continue to provide valuable genetic resources for the improvement of crop seeds.
- Modeling seed germination data to meet biodiversity conservation needs in the Mediterranean. Robust germination models can improve both restoration planning and ex situ conservation by predicting when and how seeds are most likely to establish.
- To grow or not to grow: questioning seed dormancy and thermal germination responses along elevational gradients in four plant taxa. Seed dormancy does not always follow predictable patterns across environmental gradients.
- Delayed Seed Germination as a Strategy to Cope With Environmental Stress and Disturbance. Seed dormancy follows a (fairly) predictable pattern when you look at stress and disturbance.
- Reconsidering how to dry orthodox seeds for improved ex situ conservation outcomes. Conventional wisdom about drying orthodox seeds before storage may deserve re-evaluation, and refining drying protocols could enhance long-term viability and strengthen the effectiveness of seed banks.
- Short periods dominate mast seeding across diverse tree species. A broad analysis of mast seeding reveals that many tree species synchronize seed production over relatively short recurring intervals rather than highly irregular cycles.
Brainfood: Unusual data edition
- The Broad Spectrum Species: Plant Use and Processing as Deep Time Adaptations. Hundreds of plant species, many now forgotten, show up in archaeological assemblages stretching back tens of thousands of years. Exploiting an astonishing diversity of plants was a fundamental human adaptation long before agriculture. And the data was kinda always there.
- Evaluating cultivars for pollinator gardens. Some ornamental cultivars attract more pollinators than the wild plants they were bred from. The relationship between genetic modification through breeding and ecological function is not always straightforward. And I now want to see the descriptor “pollinator attractiveness” in evaluation datasets.
- Chemotypic Diversity and Integrated Metabolic Profiling of Myrtle (Myrtus communis L.) from Mediterranean Turkey. Dozens of different chemical compounds vary dramatically among individual myrtle plants that look much the same to the naked eye.
- Essential oil composition and ethnobotanical survey of male and female Juniperus seravschanica Kom. (Cupressaceae) in Iran. Traditional knowledge and chemical profiling show that juniper male shoots, female shoots and cones each produce distinct blends of essential oils, exposing a surprising layer of sex-linked diversity within a single species.
- Earth Metabolome and Digital Botanical Gardens Initiatives: Chemodiversity Knowledge for Biodiversity Conservation. Millions of plant-produced molecules remain undocumented, forming an invisible dimension of biodiversity. We need global digital infrastructures to catalogue this vast reservoir of chemodiversity before it disappears. Of course we do.
- Herbaria Provide a Valuable Resource for Obtaining Informative mRNA. Decades-old herbarium specimens still contain usable messenger RNA, opening the door to studying historical patterns of gene expression from preserved plant collections.
- The Politics of Open Infrastructures: Power, Governance, and Justice in Digital Knowledge Practices. Data infrastructures may be open, but control over them often is not. And that probably goes even more for the unusual sorts of data represented by the above papers than for the crop diversity data we normally deal with here.
Brainfood: Indigenous edition
- Rapid adaptive increase of amylase gene copy number in Indigenous Andeans. Indigenous Andean populations evolved exceptionally high copy numbers of the AMY1 salivary amylase gene, likely linked to long-term adaptation to starch-rich diets associated with potato domestication roughly 10,000 years ago.
- Horse genetics, archaeology, and the beginning of riding. Horse domestication was not a sudden genetic event beginning around 2200–2100 BCE, but a long and regionally varied process in which Indigenous Eurasian pastoralists progressively managed, rode, milked and selectively bred multiple horse lineages over many centuries, transforming mobility and social organization well before the rise of the dominant modern domestic horse lineage.
- Bridging biodiversity and food systems: A nationwide synthesis of non-conventional food plants (PANCs) in Brazil. Brazil’s non-conventional food plants (PANCs) and associated Indigenous and traditional knowledge could help build more diverse, climate-resilient and socially inclusive food systems while strengthening biodiversity conservation, rural livelihoods and public food programs.
- Indigenous Wisdom for a Changing World: Bridging Traditional Ecological Knowledge and Biodiversity Conservation. Sacred groves and other community-managed landscapes in central Ethiopia conserve high levels of biodiversity through Indigenous institutions, ritual practices and traditional ecological knowledge, suggesting that effective conservation depends on treating cultural stewardship systems as integral to ecological resilience rather than as secondary to scientific management.
- When Knowledge Isn’t Free: Legal and Ethical Imperatives of Protecting Indigenous Intellectual Property. There’s a persistent mismatch between Western intellectual-property regimes and Indigenous concepts of collective ownership, biocultural heritage and intergenerational custodianship of knowledge, and that’s unfair.
- Crediting and citing Indigenous Knowledges within research. Biodiversity conservation becomes more effective when Indigenous scientists and communities participate as equal partners rather than merely as local stakeholders or informants.
Brainfood: Silk Road, Wheat domestication, Peanut domestication, Olive wild relatives, Pearl millet movement, Maori horticulture, Wild meat, Fermentation
- 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.
