- Commercial Crop Yields Reveal Strengths and Weaknesses for Organic Agriculture in the United States. The headline will be that organic yield is 80% of conventional, but the results are far more nuanced than that suggests.
- Genetic Distinctiveness of Rye In situ Accessions from Portugal Unveils a New Hotspot of Unexplored Genetic Resources. More collecting needed.
- A Consensus Proposal for Nutritional Indicators to Assess the Sustainability of a Healthy Diet: The Mediterranean Diet as a Case Study. 13 indicators of sustainability described, from “Vegetable/animal protein consumption ratios” to “Diet-related morbidity/mortality statistics.”
- Reconciling the evolutionary origin of bread wheat (Triticum aestivum). One slightly changed ancestral subgenome, one much-changed ancestral subgenome, and one weird hybrid subgenome involving the previous two plus another. Basically, we were insanely lucky to get wheat.
A genebank in need
Our vault, where we store over 20,000 varieties of rare and heirloom seeds is critical to that mission. And the vault is failing. It has a crack in the floor, which could potentially lead to unstable temperatures and structural instability.
Do consider helping Seed Savers Exchange. They do great work. As, indeed, do thousands of seed savers around the world.
Damaging dichotomies
To mark the IUCN World Conservation Congress, which starts tomorrow with a visit by President Obama, I have a post over at the work blog arguing (well, implying) that the biodiversity conservation community has got itself into a tangle dividing its work into in situ and ex situ 1. When will we see genebanks, including Svalbard (about which there’s a new book out, incidentally), as an integral part of biodiversity conservation, rather than a reluctantly tolerated add-on? Answers on a postcard, please.
Mansplaining genebank terminology
I’m defining genebank terms over on Twitter today. Let me know if there’s one you particularly want explained.
Brainfood: Lentil diversity, Cacao diversity, Larch distribution, Tea diversity, Salmon breeding, Ethiopian sorghum, Brassica differentiation, Biodiversity info, Human footprint
- Genetic Diversity of Cultivated Lentil (Lens culinaris Medik.) and Its Relation to the World’s Agro-ecological Zones. 352 accessions, 54 countries, 3 agro-ecological groups (South Asia, Mediterranean, N temperate) in USDA collection.
- Association mapping of seed and disease resistance traits in Theobroma cacao L. 6 and 1 markers, respectively, based on 483 unique trees in the International Cocoa Genebank, Trinidad (ICGT).
- Historic translocations of European larch (Larix decidua Mill.) genetic resources across Europe – A review from the 17th until the mid-20th century. Humans have moved material to areas outside its native distribution, and have mixed up genetically distinct populations in some places.
- Insights into the Genetic Relationships and Breeding Patterns of the African Tea Germplasm (Camellia sinensis (L.) O. Kuntze) Based on nSSR Markers and cpDNA Sequences. African material groups according to where it was bred.
- First the seed, next the smolt? Will salmon farmers learn the right lessons from plant biotechnology? I bet not.
- Geographic patterns of phenotypic diversity in sorghum (Sorghum bicolor (L.) Moench) landraces from North Eastern Ethiopia. There aren’t any. Patterns, that is.
- Subgenome parallel selection is associated with morphotype diversification and convergent crop domestication in Brassica rapa and Brassica oleracea. Similar heading and tuberous morphotypes in the two species are due to parallel selection on genes that diverged after duplication event.
- Assessing the Cost of Global Biodiversity and Conservation Knowledge. Golly, it’s expensive!
- Sixteen years of change in the global terrestrial human footprint and implications for biodiversity conservation. Human footprint hasn’t increased by as much as might be feared, but still extends over 75% of world’s land surface. Let the mashing up with crop wild relatives hotspots begin!
