- Rice yields and yield gaps in Southeast Asia: Past trends and future outlook. If average farmers became like best-yielding farmers that would meet 2050 needs, except in the Philippines, where some more structural stuff is needed.
- Method of evaluating diversity of carrot roots using a self-organizing map and image data. The sound you hear is that of butterflies being broken on wheels.
- Bioactive compounds from Capparis spinosa subsp. rupestris. Are pretty much the same as those in subsp. spinosa.
- Constitutive Overexpression of the OsNAS Gene Family Reveals Single-Gene Strategies for Effective Iron- and Zinc-Biofortification of Rice Endosperm. So that’s a good thing, right?
- Analysis of climate paths reveals potential limitations on species range shifts. Corridors not the answer. Or not the only answer. Or not the full answer.
- An updated review of Adansonia digitata: A commercially important African tree. Do baobab scientists not sometimes long for the Time Before Reviews, when they actually, you know, did stuff?
- Genetic diversity, population structure and relationships of Tunisian Thymus algeriensis Boiss. et Reut. and Thymus capitatus Hoffm. et Link. assessed by isozymes. Dad, what’s an isozyme? Ah, son, it’s a thing people used in the Time Before DNA. The two species are different, they need to be managed in different ways.
- Potential Impact of Biotechnology on Adaption of Agriculture to Climate Change: The Case of Drought Tolerant Rice Breeding in Asia. Kinda pointless: “in severe drought both the [drought tolerant] and the conventional varieties were either not planted or, if planted, did not yield”.
Sorghum and ethnicity in Africa
Ever since I contributed to A methodological model for ecogeographic surveys of crops, and suggested that collectors should do this, I’ve been waiting for the time when it would be easy — or even possible — to map the distribution of conserved germplasm on top of cultural, ethnic or language boundaries. The problem has been that maps of such boundaries, ((And yes, I’m aware that there are problems with mapping languages et al., but for the purposes of this, let’s just say I don’t care.)) though available in various printed formats, have not been much digitized. Or at least I hadn’t come across them. Until I happened on a blog post about the Center for Geographic Analysis’ (Harvard University) WorldMap, an open source web mapping system. The layers provided include one called Ethnicity Felix 2001, which “consist of polygons and labels depicting ethnicity information based on the ‘People’s Atlas of Africa’ by Marc Felix and Charles Meur, Copyright 2001.” Perfect, I thought.
Nibbles: Collecting, US heirlooms, Sequencing NUS, Nutrition strategies, Potatoes and climate change, Italian genetics
- NSF re-invents the genebank wheel. No, that’s unfair, they’ve given much-needed money to evolutionary scientists to go out and collect seeds of 34 species in a really pernickety way.
- Heirlooms being lost (maybe) and being re-found in the US. Thanks to Eve (on FB) for both.
- A Cape tomato by any other name…
- Gates Foundation has a new nutrition strategy. Gotta admire the chutzpah of summarizing the thing in basically half a side of A4. Compare and contrast, both as to content and presentation, with the CGIAR. Unfair again, I know, but that’s the kind of mood I’m in. Jess unavailable for comment.
- Very complicated, very pretty maps about potatoes and climate change.
- “I failed to notice substantial contributions to discussions or presentations from breeders or seed organizations, the end users of so much of the research discussed.” Pat Heslop Harrison calls ’em like he seems ’em.
Nibbles: Polyculture, Melons, Cheese 2011, Australian medicinals
- Do polycultures have a role in modern agriculture? Well, do they? h/t The Scientist Gardener.
- Texas breeders go for better melons.
- “Children from the city who try this yogurt don’t like it, but they’re not healthy like my children!”
- Hotspots for Aboriginal traditional medicinal plants mapped to within an inch of their lives, thanks to GBIF.
Brainfood: Millet diversity, Maize landraces and hybrids, Potato carotenoids, Wheat domestication, Value chains, Population modeling, Rhizobium diversity, Yeast diversity, Core collection, Wild Zea, Cotton geneflow, Forest fires, Forest diseases
- Identification of trait-specific germplasm and developing a mini core collection for efficient use of foxtail millet genetic resources in crop improvement. All the goodness of Setaria italica diversity in just 35 accessions.
- Farmers’ adoption of maize (Zea mays L.) hybrids and the persistence of landraces in Southwest China: implications for policy and breeding. There are pros and cons to both hybrids and landraces, and participatory plant breeding could bring together the pros and get rid of the cons.
- Carotenoid concentrations of native Andean potatoes as affected by cooking. Some carotenoids were decreased by boiling, others not so much.
- Domestication evolution, genetics and genomics in wheat. A big summary of what we know so far and what we might learn by sequencing some wild wheat relatives.
- Research Principles for Developing Country Food Value Chains. Multidimensional demands by consumers demand multidimensional research by scientists. I think.
- Range shift promotes the formation of stable range edges. Species can move for reasons other than climate change.
- Genetic diversity of rhizobia associated with indigenous legumes in different regions of Flanders (Belgium). A new genus? In Flanders?
- Assessment of yeast diversity in soils under different management regimes. Type of management and vegetation has an effect. Yeah, well, you had to be there.
- Efficiency of PowerCore in core set development using amplified fragment length polymorphic markers in mungbean. Software for making core collections seems to work.
- Three new teosintes (Zea spp., Poaceae) from México. New entities, apparently. Species? Subspecies? More study needed, natch.
- Recent long-distance transgene flow into wild populations conforms to historical patterns of gene flow in cotton (Gossypium hirsutum) at its centre of origin. Four out of eight populations have transgenes.
