The long and winding road to crop wild relative conservation priorities
Those who follow these things will probably have noticed a certain frisson in the press over a paper in Nature Plants on setting conservation priorities for crop wild relatives. Lead authors are Nora Castañeda and Colin Khoury of CIAT, both of whom have featured here before. Good to see Nora celebrating the occasion on Twitter. She really deserves that beer.

Well, I think it’s a beer.
Anyway, I won’t go into the details of the findings here. As I say, it’s all over the news (well, relatively speaking), and you can always explore the results for yourself on the project’s website. But I did want to strike a historical note.
This whole thing started when a small group of us decided it would be kinda fun to apply fancy spatial analysis methods to data from herbaria and genebanks on the distribution of wild Phaseolus species in the Americas. Just to see if it could be done. And whether the results would make any sense.
Well, it could, and they sort of did. And many years, a major international project, two PhDs and a lot of blood, sweat and tears later, we have a global analysis across dozens of genepools and hundreds of species. It was totally worth it, but there should be easier, faster and less expensive ways to get this kind of thing done.
Mapping crop words online
Do you remember the post a few weeks ago about Jack Grieve and his method for mapping words used in tweets? He helped us to investigate to what extent it could be used to map crops in the USA.
The answer was: it depends. Anyway, now you can try it for yourself. Go crazy.
Brainfood: PVP in Africa, Tomato disease resistance, Open source seeds, Barley protein, Improving roots, Bambara groundnut, Indian kodo millet, Cacao diversity, Washington heirloom beans, Mato Grosso cassava, Balanites biotech, Intensive Europe
- Opportunities and Threats to Harmonisation of Plant Breeders’ Rights in Africa: ARIPO and SADC. While the intention of ARIPO and SADC is to create a single internal market for protected varieties in Africa, “the end result may look quite differently.”
- Evaluation of Resistance to Ralstonia solanacearum in Tomato Genetic Resources at Seedling Stage. Out of 285 varieties from 21 countries in the Korean genebank, 4 may be resistant to bacterial wilt.
- Following the Open-Source Trail Outside the Digital World: The Case of Open-Source Seeds. “…by not rejecting the idea of property, including intellectual property, but rather attempting to manage it differently, it creates its own enclosures.”
- Grain protein concentration and harvestable protein under future climate conditions. A study of 108 spring barley accessions. Higher CO2 and temperatures lead to higher protein concentrations but lower yields, so lower harvestable protein. The good news is that there’s variation in the response of varieties.
- How can we harness quantitative genetic variation in crop root systems for agricultural improvement? Apparently we still don’t have a mechanistic understanding of root growth, and we’ll need it if we’re going to improve function.
- Bambara Groundnut for Food Security in the Changing African Climate. It’s nutritious, it’s drought tolerant, and it can be intercropped. What’s not to like?
- Neutral and functional marker based genetic diversity in kodo millet (Paspalum scrobiculatum L.). Indian material falls into 4 groups, with Bihar being very diverse. African genepool and wild species should be useful in broadening base in India.
- Origin, Dispersal, and Current Global Distribution of Cacao Genetic Diversity. We’ve come to the limit of the usefulness of the Pound Collection.
- Exploring the role of local heirloom germplasm in expanding western Washington dry bean production. 24 bean varieties have been grown in the area for 20–130 years, representing a useful starting point for participatory plant breeding.
- Growing Cassava (Manihot esculenta) in Mato Grosso, Brazil: Genetic Diversity Conservation in Small–Scale Agriculture. Lots of diversity within communities, and differences among communities. Varieties with same name not necessarily genetically similar.
- Establishment of an in vitro propagation and transformation system of Balanites aegyptiaca. So?
- Mapping cropland-use intensity across Europe using MODIS NDVI time series. Four indicators show highest cropping intensity in Germany, Poland, and the eastern European Black Earth regions, and lowest in eastern Europe outside the Black Earth region. Interesting to mash this up with agricultural biodiversity? Like earthworms?
Vulnerability of crop wild relatives kinda sorta mapped
There’s a nice paper in Nature on how sensitive vegetation around the world is expected to be to climate change. Here’s the money map.
Cries to be mashed up with crop wild relative distributions and gap analysis.
