- Small farms are not just beautiful. Yes, the original paper was in Brainfood back in March, but this website seems to be new.
- DivSeek has a new strategic plan to “improve the generation and sharing of information about global plant genetic resources”: accelerate, add value, educate. Small farms unavailable for comment.
- Speaking of sharing information on global PGR, we need to do that for wheat genes, wheat gene scientists say.
- Probably for tannins too, come to think of it.
- FAO says climate change will make pests and diseases worse.
- FAO also says that livestock are not as bad as many people think.
- The sincerest for of flattery on display in South Korea.
The making of GapAnalysis.R
A big thank you to Colin Khoury, Julian Ramirez, Chrystian Sosa, and Dan Carver for this guest post, reminding us of the history of conservation gap analysis work at CIAT and other CGIAR centres during the past decade and more.
Maps have helped people find their way for at least 2500 years, so it’s no surprise that geographic methods have been part of the portfolio of tools used to try to understand patterns and distributions of crop diversity, and, more recently, crop genetic erosion, ever since these topics began to garner the interest of scientists and conservationists. Innovations in digital mapping tools, made possible by developments in computer processing and the internet, have enabled continual leaps in the power and efficiency of such methods throughout the past few decades.
CGIAR embraced geographic information system (GIS) research tools about as soon as they were developed. At the International Center for Tropical Agriculture (CIAT), the International Potato Center (CIP), the International Plant Genetic Resources Institute (IPGRI, now Bioversity International), and the International Rice Research Institute (IRRI), among others, scientists began to apply available GIS tools to genetic resources conservation, and then develop their own suite of methods, programs, and datasets, often in collaboration with national partners and academics (e.g. wild potatoes, peanuts, chile pepper, and peanut/potato/cowpea, as well as climate data). Some of these developments, such as FloraMap and DIVA-GIS (and more recently CAPFITOGEN, by other researchers), have been aimed at making these tools easier to use by those in genetic resources community without extensive GIS experience: an important effort toward greater accessibility, even if it has met with mixed success.
By the 2000s, crop wild relatives were gaining attention as important genetic resources for crop breeding, and would soon be specifically targeted for conservation both by the Convention on Biological Diversity (CBD’s Aichi Target 13), and the Sustainable Development Goals (SDG Target 2.5). It was increasingly important, therefore, that conservation research tools were applied to these useful wild plants, and fortunate that the groundwork for GIS applications had already been laid by a decade or so of research. Through the second phase of a cross-CGIAR initiative called the Global Public Goods Project 2 (GPG2), run from 2007-2010, the distributions of the wild relatives of ten CGIAR mandate crops were mapped, with priorities for further collecting for ex situ conservation identified.
Brainfood: Sorghum rescue, Barley mixtures, Agroecology, Tepary genome, DSI x 2, Cryo guac, Seed regulation, Recipe design, White clover diversity, IK wheat, High maize
- The recent evolutionary rescue of a staple crop depended on over half a century of global germplasm exchange. Sorghum in Haiti was saved from pest by breeders mixing up material from all over the place.
- Does crop genetic diversity support positive biodiversity effects under experimental drought? Not straightforwardly, at least for barley cultivar mixtures in pots.
- A Nutrition-Sensitive Agroecology Intervention in Rural Tanzania Increases Children’s Dietary Diversity and Household Food Security But Does Not Change Child Anthropometry: Results from a Cluster-Randomized Trial. Well at least it’s more straightforward than the above.
- The tepary bean genome provides insight into evolution and domestication under heat stress. Better heat adaptation than common bean, but less disease and pest resistance.
- The international political process around Digital Sequence Information under the Convention on Biological Diversity and the 2018–2020 intersessional period. Can’t take the above for granted.
- Practical consequences of digital sequence information (DSI) definitions and access and benefit‐sharing scenarios from a plant genebank’s perspective. Genebanks trying not to take the above for granted.
- Cryopreservation of Woody Crops: The Avocado Case. There’s been a breakthrough in shoot tip cryopreservation.
- Using Regulatory Flexibility to Address Market Informality in Seed Systems: A Global Study. Regulatory flexibility would certainly be a breakthrough for linking formal and informal seed systems. And, incidentally, not bad for DSI either.
- A recipe development process model designed to support a crop’s sensory qualities. When you want to make a recipe for a new ingredient (crop or heirloom variety), start with what makes the ingredient special, not with what might make the end-product special.
- Genetic diversity and population structure analysis in a large collection of white clover (Trifolium repens L.) germplasm worldwide. Native and introduced populations are genetically differentiated.
- Limited haplotype diversity underlies polygenic trait architecture across 70 years of wheat breeding. Crunch time for UK wheat breeders: continue shuffling within the existing diversity, or expand it?
- Molecular Parallelism Underlies Convergent Highland Adaptation of Maize Landraces. Adaptation to high altitude from the SW US to the Andes was due to wild genes from the Mexican highlands.
Nibbles: Yeast, Asian veggies, Ancient malt, AYB
- Researchers manipulate biodiversity to reduce the amount of alcohol in wine. For some reason.
- Promoting the cultivation of traditional Asian vegetables in the US. That’s more like it.
- Reproducing ancient malting. Now you’re talking.
- Giving African yam bean a helping hand. Faith in researchers duly restored.
Nibbles: Cryo genebanks, In situ network, Biodiversity fund, Swiss grape, Coffee history, Wild plant use, Plant breeding impact
- Panel discussion on cryopreservation in genebanks on 25 June, save the date!
- Forget cryo, what about a network of European network for the conservation and sustainable use of plant genetic resources, in cultivation and in the wild? See who is interested. And express interest yourself.
- Germans launch Legacy Landscape Fund for biodiversity hotspots. European in situ PGR conservation network unavailable for comment. Let alone cryo genebanks.
- I wonder if that European on-farm conservation network will include the Completer grape, ideally in a monastery.
- Decolonizing coffee. Somebody want to write about religion and crops?
- Using wild plants in south and southeast Asia. Maybe they need a network too.
- Plant breeders say plant breeding is really important.
