- Mineral nutrient composition of vegetables, fruits and grains: The context of reports of apparent historical declines. Apparent being the operative word. This is a couple of years old but always worth recycling. (There’s also this Politico piece from a couple of years back on the “nutrient collapse.”)
- Phenolic composition and antioxidant properties of ex-situ conserved tomato (Solanum lycopersicum L.) germplasm. But there’s always room for improvement.
- Genetic Diversity and Population Structure of Tomato (Solanum lycopersicum) Germplasm Developed by Texas A&M Breeding Programs. Plenty of diversity out there for it.

- Was the Green Revolution intended to maximise food production? No, apparently it was to encourage a move to commercial production in specific areas.
- Musa balbisiana genome reveals subgenome evolution and functional divergence. The starch synthesis pathway is more active than in the A-subgenome. There’s probably more, but that’s all I could understand.
- Pixelating crop production: Consequences of methodological choices. Crop prices and market access had little effect on the robustness of the SPAM2005 spatial production allocation model.
- Phylogenetic and population structural inference from genomic ancestry maintained in present‐day common wheat Chinese landraces. 3000 old wheat not dissimilar to current landraces in W China.
- Stacking three late blight resistance genes from wild species directly into African highland potato varieties confers complete field resistance to local blight races. But it’s GM so it doesn’t count, right?
- Genomic signatures of seed mass adaptation to global precipitation gradients in sorghum. Drought stress led to bigger grains.
- Nitrogen addition reduced ecosystem stability regardless of its impacts on plant diversity. Stability depends on more than just diversity. In grasslands.

- Australia supports Pacific genebank. No wheat in sight.
- Saving coconut. No, not in the Pacific.
- The history of chocolate and vanilla. The crops, not the ice cream.
- Speaking of ice cream: maybe someone should try making some out of these tasty endangered fruits before it’s too late.
- Speaking of tasty: basmati.
- Speaking of rice: this guy has 1420 varieties.
- Hey, it’s not about the taste: it’s the ethics too, stupid. But, being wine, it’s also about the taste.
- Speaking of ethics: what good is forest conservation if it stops people accessing wild foods.
- At least one senator gets it.
- You’ve got a few weeks to register for a potato breeding course. Using CWR, no less.
- Amazing pics of Chinese aquaculture.
- Chinese efforts to save ancient trees. No connection with above at all. And no pics.

- Interactive atlas of US forests. There goes the afternoon. Imagine if if ever got mashed up with the global fire atlas.
- Automated Red List assessments. Wow.
- The MERL has an exhibition on the history of farming. One of my favourite museums, one of my favourite topics. My cup runneth over.
- Gin made from peas. Sometimes I hate farming.
Brainfood: Biodiversity & production, Tertiary tomato, Maya collapse, Restoration opportunities, Mixtures, Synchronous crop failure, Boswellia future, Soya diversity, Genetic load, Domestication, Ag & biodiversity, Cotton domestication, Food preservation
- Contributions of biodiversity to the sustainable intensification of food production. They are various and considerable, but context-specific. See additional data here. See also everything below…
- Development of interspecific hybrids between Solanum lycopersicum L. and S. sisymbriifolium Lam. via embryo calli. Tertiary genepool? No problem.
- The Role of Diet in Resilience and Vulnerability to Climate Change among Early Agricultural Communities in the Maya Lowlands. More diverse diets allowed Maya to survive the droughts of the Late Pre-Classic Period (AD 100–300) better than those of the Terminal Classic Period (AD 750–1000).
- Global restoration opportunities in tropical rainforest landscapes. Massive mashing up of spatial datasets concludes that top 10% areas for potential return of benefits and feasibility of forest restoration are located largely within conservation hotspots and in countries committed to the Bonn Challenge, but cover only a small portion of the Key Biodiversity Area network.
- Plant domestication disrupts biodiversity effects across major crop types. Wild relatives are better at living in diverse mixtures than their descendant crops.
- Synchronous crop failures and climate-forced production variability. ENSO has caused global crop failures. Which are likely to get more frequent.
- Frankincense in peril. Because of cows and fire.
- Identification of Loci Controlling Adaptation in Chinese Soybean Landraces via a Combination of Conventional and Bioclimatic GWAS. Three geographic sub-populations among 2000 diverse landraces; 12 SNPs associated with variation in 3 bioclimatic variables at collecting sites.
- Estimates of genetic load in small populations suggest extensive purging of deleterious alleles. Counterintuitively, rapid declines cause worse genetic load for more diverse species.
- Grazing animals drove domestication of grain crops. Small-seeded herbaceous annuals were mainly animal-dispersed, which meant they grew in dense stands on nitrogen hotspots near water sources, making them easily harvested. Hey presto, crops!
- Global impacts of future cropland expansion and intensification on agricultural markets and biodiversity. Expansion mostly threatens biodiversity in Central and South America, intensification in Sub-Saharan Africa, India and China. Prices lower everywhere.
- Domestication and varietal diversification of Old World cultivated cottons (Gossypium sp.) in the Antiquity. G. arboreum first domesticated in Baluchistan 8000 years BP, G. herbaceum much later in Nubia. But they’re really difficult to tell apart in archaeological remains.

- Rapid detection of stressed agricultural environments in Africa under climatic change 2000–2050 using agricultural resource indices and a hotspot mapping approach. Increasing trouble for Tanzania, Zimbabwe, and to a lesser extent Ethiopia. But will biodiversity, disease monitoring and food insecurity prediction help?
- Kavalactones and Flavokavins Profiles Contribute to Quality Assessment of Kava (Piper methysticum G. Forst.), the Traditional Beverage of the Pacific. High-throughput HPTLC will do the job.
- Transcriptome and organellar sequencing highlights the complex origin and diversification of allotetraploid Brassica napus. 6 genetic groups: Winter rapeseed in Europe and America, Rutabaga, Spring rapeseed, Siberian kale, Winter rapeseed in East Asia, and Winter rapeseed in Europe and South Asia. No evidence of multi-origin.
- Parallels between natural selection in the cold‐adapted crop‐wild relative Tripsacum dactyloides and artificial selection in temperate adapted maize. Artificial selection for temperate adaptation in maize involved the same genes as natural selection for temperate adaptation in Tripsacum.
