Beating a (cassava) virus in SE Asia
CMD being Cassava Mosaic Disease, one of the most damaging of crop viruses. The question, and photo, come from a recent tweet from a regional team coordinated by the entity formerly known as CIAT that is trying to develop “sustainable solutions to cassava disease in SE Asia” with support from ACIAR and CGIAR’s Research Program on Roots, Tubers and Bananas.
Some of the resistant varieties that are doing so well in the photo are identified elsewhere in the thread as the IITA lines TME3, TMEB419, TMS980581, TMS980505 and TMS920057.
But this PowerPoint from Dr Xiaofei Zhang explains that those were only the beginning. Additional promising material came from a bunch of other sources.
Agriculture on the steppe
I’ve been sitting on a couple of linked press releases from the Max Planck Institute for the Science of Human History for a few months now and it’s about time I did something about them. So here goes. The releases summarize two papers deriving from the analytical work of Dr Shevan Wilkin and her colleagues on skeletal remains previously excavated from Mongolian archaeological sites spanning a wide range of dates back to 5000 year ago.
The first paper focuses on dairy proteins from dental plaque to suggest that steppe pastoralists in what is now Mongolia started consuming ruminant milk at least 5000 years ago. Horse milk came in about 3000 years ago, coinciding with the first evidence of horse bridling and riding, and was mainly fermented. Finally, camel milk started to be consumed during the Mongol Empire, 800 years ago. How lactose intolerant populations dealt with this is still unknown, but may have involved changes in the gut microbiome.
Next, looking at the N and C isotopes in dental enamel and rib collagen enabled the researchers to investigate the wider dietscape. In particular, they found evidence of increased millet (Panicum miliaceum and/or Setaria italica) 1, consumption around 2000 years ago, but only in some individuals, mainly living close to the heartland of the polity (the Xiongnu Empire) which developed at that time.
Clearly, some ancient Mongolians did not completely conform to the nomadic herder stereotype of popular imagination.
LATER: Speaking of broomcorn millet (Panicum miliaceum), here’s a paper that just came out that dates its arrival in Europe to the 16th century BC, and its rapid spread during the subsequent two centuries, i.e. during the Bronze Age. So, having been domesticated 8000 years ago in NE China, it was being widely consumed in Europe before Mongolia. And here’s one we prepared earlier…

- ntbox: an R package with graphical user interface for modeling and evaluating multidimensional ecological niches. Yes, another one, deal with it.
- Global targets that reveal the social–ecological interdependencies of sustainable development. The post-2020 framework should not have separate targets for social and ecological outcomes.
- Integrating agroecological production in a robust post-2020 Global Biodiversity Framework. Case in point?

- Global Cropland Connectivity: A Risk Factor for Invasion and Saturation by Emerging Pathogens and Pests. Nice maps of ease of movement among different cultivation areas of vegetatively propagated crops. Could be used to model movement of genetic resources as well as of pests/diseases?
- Global patterns of population genetic differentiation in seed plants. More population differentiation for tropical, mixed‐mating, non‐woody species pollinated by small insects, and lower for temperate, outcrossing trees pollinated by wind. Could perhaps be mashed up with this fragmentation database.

- There’s a sort of mycological culinary hotspot in Yunnan… Yeah, I thought that too.
- Signs found of old banana cultivation in Australia. Well, kinda. As in not as old as in PNG, and not mainland Australia.
- Really, really old horse butchery site in southern England excavated. When the Brits ate horses. Well, kinda.

- Speaking of USDA, here’s another job.
