- Analysis of genetic diversity in farmers’ rice varieties in Sierra Leone using morphological and AFLP markers. Still a lot of diversity in traditional rice after the war, both among and within landraces, mostly among, organized regionally, and recognized by local names.
- Simultaneous selection for resistance to five bacterial, fungal, and viral diseases in three Andean × Middle American inter-gene pool common bean populations. Thanks goodness for multiple independent domestication events. And genebanks.
- Present Spatial Diversity Patterns of Theobroma cacao L. in the Neotropics Reflect Genetic Differentiation in Pleistocene Refugia Followed by Human-Influenced Dispersal. So need to collect in areas at the margins or just outside the refugia if you want high diversity. But of course that may already be ex situ. But wait, didn’t you just do the analysis based on the provenance of ex situ holdings?
- An ancient duplication of apple MYB transcription factors is responsible for novel red fruit-flesh phenotypes. The whole genome got duplicated during evolution of the apple and the red flesh phenotype is controlled by loci in both copies, but in different ways.
- What is the form of the productivity–animal-species-richness relationship? A critical review and meta-analysis. Positive.
- Spatial Structure and Climatic Adaptation in African Maize Revealed by Surveying SNP Diversity in Relation to Global Breeding and Landrace Panels. Distinct Sahelian, Western and Eastern clusters. Some SNPs associated with high temperatures.
- MtDNA analysis of global populations support that major population expansions began before Neolithic Time. Humans needed good weather to thrive, not agriculture.
- Genetic gap analysis of wild Hordeum taxa. Argentina?
- The Impact of Climate Change on Indigenous Arabica Coffee (Coffea arabica): Predicting Future Trends and Identifying Priorities. Generally very bad to disastrous, but some “core localities” will be ok, and therefore could be used for in situ conservation. Interestingly, genebank accession locality data not used.
- The genus Acacia (Fabaceae) in East Africa: distribution, diversity and the protected area network. No such luck for Acacia, I’m afraid.
- Monocropping Cultures into Ruin: The Loss of Food Varieties and Cultural Diversity. Are you sure you want to know what a sociologist and a political scientist have to say on the matter?
Nibbles: Value chains, CAP, Intercropping, Tree trouble, Phenotyping
- Sustainable value chains made easy. Perhaps too easy.
- An end to crazy EU agricultural subsidies? Don’t hold your breath. What would it mean for agricultural biodiversity?
- Yesterday it was rotation, today it is intercropping, and more. Is there something in the air?
- Ten new things we learned about trees this year. The one I would add is that eucalypts are rain forest species.
- Way more about high-throughput phenotyping than I need to know. But somehow still less than I’d like to know. Thanks, Tom.
Brainfood: Chinese fermented fish, Yeast diversity, Wild papayas, Milpa nutrition, Rare wild sunflower, Albanian pomegranate, Wheat mixtures, Climate change yield decline
- Chemical and microbial properties of Chinese traditional low-salt fermented whole fish product Suan yu. “The values of Enterobacteria and Pseudomonads were under the detection limits in six different brands” is about the best that can be said for it.
- Tapping into yeast diversity. Some new, diverse wild lineages in China may tell us important things about yeast ecology, evolution and domestication.
- Genome size variation among sex types in dioecious and trioecious Caricaceae species. Lots of retrotransposons, and sex chromosomes in some species.
- The Archaic Diet in Mesoamerica: Incentive for Milpa Development and Species Domestication. The diet preceded the crops.
- Genetic diversity and population structure in the rare Algodones sunflower (Helianthus niveus ssp. tephrodes). Low diversity overall, but some populations quite distinct. Which tells you about how to conserve it.
- Albania, the domestication country for pomegranate (Punica granatum L.). Well, maybe.
- Mixtures of genetically modified wheat lines outperform monocultures. Two transgenes are better than one.
- Climate change impacts on crop productivity in Africa and South Asia. -8% overall. The surprise? Sorghum declines more than maize in Africa, less in S Asia.
Nibbles: Taro value addition, Tree genomics special issue, MSB database, Japanese tubers, Ghana farmer awards, Omani genebank, Mexican cemeteries, Rotation, Root interactions
- Dalo chips! With illustrative goodness.
- Tree genomes! Whole journal-full.
- Seeds! From Kew’s Millennium Seed Bank, that is. In a database. Or two. Online.
- Japanese tubers! If anyone can find the actual video, I’d be very grateful. It’s not here yet. Or here. And I also want to find out more about the mythical Professor Sweet Potato.
- Best farmer awards in Ghana! “He cultivates diverse crops…” Ah but not everyone is happy. Via.
- An Omani genebank! Still “under process”? There was one of sorts 20 years ago when I worked there.
- Day of the Dead! Nuff said.
- Crop rotations! The NY Times plays catchup.
- John Innes Institute video! Explains a couple of papers in Current Biology on root-microbe interactions, where the microbes are both good and bad.
Nibbles: Audacity of hops, Potato catalogues, Heirloom apples, Heirloom wheat, UK systematics, Millennial olives, CIAT celebrates, IITA in the news, Agrobiodiversity marketing awards, Insects in orchards, Quinoa
- U. of Minnesota has a poster of the pedigree of hop varieties which I covet.
- Cool catalogue of the native potatoes of a bit of Ecuador. Via Red Electronica de la Papa.
- Stark photos of a few heirloom apples, with descriptions.
- Meanwhile, Brockwell Bake sows some heritage wheats. With stark photo
- Report on the state of UK capacity in taxonomy. How many countries have reports on the state of their taxonomy? Anyway, here’s some of that capacity at work.
- Farrago on some old olives in Jerusalem.
- CIAT celebrates 45 years of existence.
- Meanwhile, IITA pushes soil fertility management and cassava.
- Arca-Deli Awards awarded.
- Defra’s latest Biodiversity News has stuff on the importance of insect biodiversity to pest control and pollination in orchards.
- The International Year of Quinoa, which is next year, has a website, and all sorts of associated social networking goodness. And here’s a nice little student video on the crop, for a somewhat different perspective.
