- ‘White gold’ guano fertilizer drove agricultural intensification in the Atacama Desert from ad 1000. And maize was at the heart of it.
- What’s new during the first millennium BCE in Greece? Archaeobotanical results from Olynthos and Sikyon. Not maize, alas, but what you’d expect, plus pine and sesame.
- Local adaptation contributes to gene expression divergence in maize. Stress-response genes are the ones which have been selected. No word on whether any of them were important in the Atacama.
- Genotyping tools and resources to assess peanut germplasm: smut-resistant landraces as a case study. Ok, so it sounds like the resistant line that was previously used is virtually identical to an accession in the USDA collection.
- Do We Need to Identify Adaptive Genetic Variation When Prioritizing Populations for Conservation? No, but we’ll need it to prioritize use, surely?
- Incorporating Realistic Trait Physiology into Crop Growth Models to Support Genetic Improvement. We’ll need better growth models too.
- Wild to domesticates: genomes of edible diploid bananas hold traces of several undefined genepools. 3 of them, in fact, in both SE Asia and New Guinea.
- Evolution of the bread wheat D-subgenome and enriching it with diversity from Aegilops tauschii. Three lineages were involved in the hybridizations that led to bread wheat. Coincidence?
- De novo genome assembly of two tomato ancestors, Solanum pimpinellifolium and Solanum lycopersicum var. cerasiforme, by long-read sequencing. Thousands of genes not found in the cultivated crop, apparently.
- Genomic mechanisms of climate adaptation in polyploid bioenergy switchgrass. Introgression from the northern genepool (one of three) was really important in adaptation after the glaciers retreated. Gene duplication also involved in adaptation.
- Economic Studies Reinforce Efforts to Safeguard Specialty Crops in the United States. Where “safeguard” means “provide clean planting material.”

- Rapid assessments of the impact of COVID-19 on the availability of quality seed to farmers: Advocating immediate practical, remedial and preventative action. Structural weaknesses ruthlessly exposed.
- Initial Investment in Diversity Is the Efficient Thing to Do for Resilient Forest Landscape Restoration. Spend the money on securing diverse seeds up front, you cheapskates. No word on what the effect of the pandemic.
- Ten golden rules for reforestation to optimize carbon sequestration, biodiversity recovery and livelihood benefits. Right seeds, right species, right place, the right way. But save forests first.
- The impact of near-real-time deforestation alerts across the tropics. Getting alerts saves forests, especially in protected areas, but only in Africa.
- Integration of georeferenced and genetic data for the management of biodiversity in sheep genetic resources in Brazil. Travel 300 km for a genetically different sheep. I wonder if it’s the same for trees.
- Worldwide occurrence records suggest a global decline in bee species richness. 25% fewer species in GBIF in past 25 years. Yeah but there may be alternative explanations for that, as a bee taxonomist points out. Non-Twitter link available too.
- Investigating genetic relationship of Brassica juncea with B. nigra via virtual allopolyploidy and hexaploidy strategy. Wild relative could be used to synthesize some really cool mustards.
- Seed storage behavior of Musa balbisiana Colla, a wild progenitor of bananas and plantains – Implications for ex situ germplasm conservation. Orthodox, but difficult to regenerate.
- Mineral nutrient composition of vegetables, fruits and grains: The context of reports of apparent historical declines. No evidence for systematic declines in micronutrient concentrations.
- A Study on the Biodiversity of Pigmented Andean Potatoes: Nutritional Profile and Phenolic Composition. Lots of diversity in micronutrients in traditional landraces. No word on temporal changes.
- Status and prospects of genome‐wide association studies in plants. Dissecting complex traits has never been easier, and is getting easier. It says here.
- A review of the interactions between biodiversity, agriculture, climate change, and international trade: research and policy priorities. Policy priorities? Increased recognition of international trade in biodiversity targets, goals, and policy; and increased communication of the impacts of food on biodiversity.

- Perennial Staple Crops: Yields, Distribution, and Nutrition in the Global Food System. Most perennial staple crops are not as well known or widely grown as annual staple crops, but maybe should be.
- Determining appropriate interventions to mainstream nutritious orphan crops into African food systems. Look to the supply of seeds.
- Diversity and conservation of traditional African vegetables: Priorities for action. Focus on conserving diversity West Tropical Africa and southern Cameroon. And then look to the supply of seeds everywhere, presumably.
- The origins of agriculture: Intentions and consequences. Domestication happened pretty much all by itself, through co-evolution.
- The role of the microbiota in human genetic adaptation. Co-evolution happened with the gut microbiota as well as with plants.
- Genome analyses reveal the hybrid origin of the staple crop white Guinea yam (Dioscorea rotundata). Unclear if people were involved.
- Crop adaptation to climate change as a consequence of long‑term breeding. Better to focus on the slow but steady accumulation of small effects. By people, presumably.
- Trends of genetic changes uncovered by Env- and Eigen-GWAS in wheat and barley. Maybe you don’t even need to measure the results of those small effects.
- Genetic Diversity of Coffea arabica. We need to catalogue all germplasm collections, together with their marker profiles, and make material and data easily available. Easier said than done.
- Farmers’ social networks and the diffusion of modern crop varieties in India. Caste affects adoption of new varieties.
- From garden to store: local perspectives of changing food and nutrition security in a Pacific Island country. Those that have access to stores, and therefore enough food, don’t have a well balanced diet, and those that don’t have store have a better balanced diet but occasionally not enough food. No word on modern varieties.
- The role of the milpa in food and nutritional security in households of Ocotal Texizapan, Veracruz, Mexico. Who needs stores?
- Dilemmas of protection: decolonising the regulation of genetic resources as cultural heritage. But are the above natural or cultural resources?
- A meta-analysis contrasting active versus passive restoration practices in dryland agricultural ecosystems. Just add water.
- Soil biodiversity enhances the persistence of legumes under climate change. If you want to keep legumes, and thus diversity, in your vegetation under climate change, better maintain soil biodiversity. Or add water, presumably.
- Soil microbial legacy drives crop diversity advantage: linking ecological plant‐soil feedback with agricultural intercropping. Same as above, but for intercropping.
- Effect of high temperature drying on seed longevity of Bambara groundnut (Vigna subterranea) accessions. Initial drying at 45°C/35% RH for 8 days before moving to a more conventional 17°C/15% RH can be good for some accessions, but which?
