Brainfood: Sorghum core diversity, Indian mango diversity, Montia potential, Assisted migration, Corchorus diversity, Soil DNA, Fire!, Coffee pest, Earthworms

Making life simpler for you, we have created an open Mendeley group for the papers we link to here. If you’re already using Mendeley, feel free to join the group (and use it to suggest papers we might miss). You can also discuss papers there, but frankly, we’d prefer you to do that here. Or on Facebook. Even if you don’t use Mendeley, you can subscribe to the RSS feed from the group and get stuff that way. Are we cool, or what?

Variation in flowering time in sorghum core collection and mapping of QTLs controlling flowering time by association analysis. 4 QTLs and 7 loci detected under different conditions. Is that, like, a lot?
Evaluation of genetic diversity among commercial cultivars, hybrids and local mango (Mangifera indica L.) genotypes of India using cumulative RAPD and ISSR markers. Just one big happy family.
Montia fontana L. (Portulacaceae), an interesting wild vegetable traditionally consumed in the Iberian Peninsula. Aquatic herb has high fibre and lipids. High oxalate too though. Breeders enjoined to get to work. On Montia. Riiiiight.
Taking stock of the assisted migration debate. It’s REALLY complicated. Scientists are not that great at explaining it. More work needed all round. But now we have fancy diagrams.
Genetic diversity and relationships in Corchorus olitorius (Malvaceae s.l.) inferred from molecular and morphological data. Out of Africa. Ethiopia, to be exact.
Meta-barcoding of ‘dirt’ DNA from soil reflects vertebrate biodiversity. Wonder whether it works with agricultural ‘dirt.’
The human dimension of fire regimes on Earth. Entertaining gallop through the history of the use of fire to manage landscapes around the world and down the ages. Need to catch my breath here.
Some like it hot: The influence and implications of climate change on coffee berry borer (Hypothenemus hampei) and coffee production in East Africa. That title just had to come sometime, didn’t it.
A critique of earthworm molecular phylogenetics. So apparently “molecular phylogenetics is now on the verge of revolutionizing earthworm systematics.” Beyond satire.

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.
Effectiveness of strict vs. multiple use protected areas in reducing tropical forest fires: A global analysis using matching methods. Indigenous areas and multiple use are best.
The sudden emergence of pathogenicity in insect–fungus symbioses threatens naive forest ecosystems. It can happen anywhere, any time.

Nibbles: Rice biofortification, Wild walnuts, Himalayan agriculture, Eating invasives, Gissen on wine, Medicinal fungus, Soil initiative, Ag development in S Sudan, AVRDC and WorldFish, Value chains

Boffins to rice: Pump it Up!
Saving the nuts of Central Asia.
Nepali women abandon hybrids for landraces and community seedbanks. Weird thing is that it’s a WWF project. But where are the extensionists? If only they had listened in Bhutan. Ok that packed a lot of links in there.
Never saw an invasive I didn’t like.
Architectural theorist tackles wine. Not many people hurt.
Turns out 57 insect species can play host to that famous medicinal fungus that led to war between Tibetan communities a couple of years back. Which helps how?
An envelope is opened at FAO.
Seeds come to South Sudan. One hopes they are of the right kinds. And that somebody is collecting what was there before. Maybe someone should call WWF.
You want vegetables with your fish?
Crops for the Future says not all middlemen bad.

Nibbles: Kiss apple, Cryptic variation, Brewing yeast history, Sandalwood genebank, Large chile, Red dye, Grassland, Fish eco-labeling, Radiation

Koreans breed bite-sized apple for breath-freshening. Why can’t I find a picture?
Climate change bad for genetic diversity too. Tell that to taro in Cameroon.
Lager yeast came from South America. Thank you, Argentina! And more on long-distance microbe movement.
Field Gene Bank of Threatened Plants from the Western Ghats threatened.
Man’s 16-inch chili may be a record. Get your mind out of the gutter.
The source of Turkish Red.
“The proper use of native grasslands is to use them as grasslands…”
Something fishy about eco-labeling.
Japanese boffins trying to breed radiation-tolerant rice. Maybe they should look at this map in their search for parents for their crossing programme.

Brainfood: Genetic isolation and climate change, Not a Sicilian grape variety, Sicilian oregano, Good wine and climate, Italian landraces, Amazonian isolation, Judging livestock, Endosymbionts and CCD, Herbal barcodes, Finnish barley, Wild pigeonpea, Protected areas, Tree hybrids

The impact of distance and a shifting temperature gradient on genetic connectivity across a heterogeneous landscape. Climate change bringing formerly genetically isolated populations together, possibly increasing adaptive potential.
Intra-varietal genetic diversity of the grapevine (Vitis vinifera L.) cultivar ‘Nero d’Avola’ as revealed by microsatellite markers. 15 distinct genetic group among 118 plants from 30 Sicilian vineyards seems quite a lot.
Emerging cultivation of oregano in Sicily: Sensory evaluation of plants and chemical composition of essential oils. More from Sicily. Wild is best.
Effect of vineyard-scale climate variability on Pinot noir phenolic composition. Its complicated. But at least Pinot noir is not like Nero d’Avola. Or is it? Oh, crap.
Landraces in Inland areas of the Basilicata region, Italy: monitoring and perspectives for on farm conservation. “Farmer-maintainers” of landraces tend to be old and isolated. Interesting stratified sampling strategy. Basilicata? They grow horseradish there, don’t they? They do indeed.
Critical distances: Comparing measures of spatial accessibility in the riverine landscapes of Peruvian Amazonia. GIS-calculated time-based accessibility influences rural livelihoods and land use pressure. And agrobiodiversity? Apply to Basilicata next?
A morphological assessment system for ‘show quality’ bovine livestock based on image analysis. Image of side of animal fed through neural network almost as good as experts in determining how beautiful the animal is. well there’s a triumph for science.
Endosymbionts and honey bee colony losses? Something else to add to the list of possible causes of colony collapse disorder.
Commercial teas highlight plant DNA barcode identification successes and obstacles. About a third of products revealed signatures of stuff that was not listed in the ingredients, but that could be due to a number of reasons.
What would happen to barley production in Finland if global warming exceeded 4°C? A model-based assessment. Nothing good, surprisingly. Better get some new varieties, I guess.
Cajanus platycarpus (Benth.) Maesen as the donor of new pigeonpea cytoplasmic male sterile (CMS) system. Gotta love those CWRs.
Australia’s Stock Route Network: 1. A review of its values and implications for future management. Established for movement of livestock before trucks and trains, but has lots of endangered species and communities. Great value on many fronts, in fact. Needs proper governance though.
Should forest restoration with natural hybrids be allowed? Yep.
