- Genebank genomics bridges the gap between the conservation of crop diversity and plant breeding. What do we want? An accurate genotype-to-phenotype map for all seeds stored in the genebank. When do we want it? As soon as we have the money to ensure their conservation.
- The origins of cannabis smoking: Chemical residue evidence from the first millennium BCE in the Pamirs. Well, that’s like your opinion, man. Residues in incense burners used for mortuary rituals, if you must know.
- Patagonian berries as native food and medicine. Good, and good for you.
- Revisiting the Origin of the Octoploid Strawberry. Not 4 separate diploid progenitors, as another paper recently found, but rather 2 extant ones, once you re-do the math.
- The Nutritional Contribution of Potato Varietal Diversity in Andean Food Systems: a Case Study. It’s great, but it’s not enough.
- The origins and adaptation of European potatoes reconstructed from historical genomes. Sequencing of old herbarium specimens, including Darwin’s, shows that early introductions to Europe were from the Andes, and later admixed there with Chilean and wild material, forming a sort of secondary centre of diversity.
- Effect of Intensive Agriculture-Nutrition Education and Extension Program Adoption and Diffusion of Biofortified Crops. Breeding is not enough.
- Morphological characterisation and evaluation of cacao (Theobroma cacao L.) in Trinidad to facilitate utilisation of Trinitario cacao globally. Now we know which ones are the best, for different reasons.
- Evolution of US maize (Zea mays L.) root architectural and anatomical phenes over the past 100 years corresponds to increased tolerance of nitrogen stress. There has been unconscious selection for root traits resulting in better N use efficiency. An old paper, resurrected because of the next one.
- Breeding improves wheat productivity under contrasting agrochemical input levels. Breeding wheat in Europe for good performance under high input levels has not markedly affected its performance under more challenging conditions. Diversity has held up too.
- Positive outcomes between crop diversity and agricultural employment worldwide. Irrespective of input levels and economic growth rates.
- National food production stabilized by crop diversity. Crop diversity is not just good for rural employment (see above), but for year-on-year production stability too.
- Climate change and cultural resilience in late pre-Columbian Amazonia. And it was sort of the same in ancient Amazonia.
- Effects of Fairtrade on the livelihoods of poor rural workers. Fairtrade improves wages of workers in cooperatives, but not on small farms.
The past and future of the Silk Road
An interview with Robert N. Spengler III, author of Fruit from the Sands: The Silk Road Origins of the Foods We Eat ((And also the paper Origins of the Apple: The Role of Megafaunal Mutualism in the Domestication of Malus and Rosaceous Trees, which is nicely summarized here and we included in Brainfood.)) reminds me that there have been a couple of interesting papers about that part of the world recently that I was meaning to blog about.
- The domesticated apple originated half way along the Silk Road, and spread in both directions, changing most drastically in Europe due to intensive introgression from the crabapple. And more.
- In contrast, citrus fruits originated in SE Asia, and spread westward, Citrus medica (citron) reaching the Mediterranean first, and C. limon (lemon) second, both in antiquity.
- There were northern and southern routes of crop movement through central Asia, plus a maritime route.
Given the importance of the Silk Road in the domestication and the spread of crops, it is perhaps worth asking if the Belt and Road Initiative could be an opportunity for significant conservation actions. WWF has done a preliminary environmental impact assessment, but not focusing particularly on agricultural biodiversity.

- “The candidate markers could be used by any rice genebank to potentially identify varieties with seeds that are particularly short- or long-lived in storage. Viability monitoring intervals could then be customized by variety.” And wheat?
European spud history unthreaded
I could blog about the recent paper which used sequencing of old herbarium specimens, including this one collected by Darwin to trace the genetic history of potatoes in Europe. But I think I’ll let one of the authors do it instead, here.
If you don’t like Twitter, you can see the thread unspooled without going anywhere near it.

I guess diversity is in there somewhere.
