- Genetic structure within the Mesoamerican gene pool of wild Phaseolus lunatus (Fabaceae) from Mexico as revealed by microsatellite markers: Implications for conservation and the domestication of the species. Three, not just two, genepools.
- Farmer’s Knowledge on Selection and Conservation of Cassava (Manihot esculanta) Genetic Resources in Tanzania. Farmers exchange landraces, some of which are widespread and others more restricted in distribution. Only about 10% are new, but some have been lost.
- Urban cultivation in allotments maintains soil qualities adversely affected by conventional agriculture. You can farm in cities without killing the soil.
- Social institutional dynamics of seed system reliability: the case of oil palm in Benin. Farmers are being increasingly screwed.
- Natural occurrence of mixploid ginger (Zingiber officinale Rosc.) in China and its morphological variations. About a quarter of plants have both diploid and tetraploid cells, and they look different; no plants are wholly tetraploid. Weird.
- Conserving biodiversity through certification of tropical agroforestry crops at local and landscape scales. Certifying the coffee or cacao farm only is usually not enough.
- Is gene flow the most important evolutionary force in plants? May well be, which means that conservationists, among others, need to take it into account. Fortunately, they have the data-rich genomic tools to do so.
- Greater Sensitivity to Drought Accompanies Maize Yield Increase in the U.S. Midwest. It’s agronomy’s fault.
- Desiccation and storage studies on three cultivars of Arabica coffee. Yeah, not orthodox. Didn’t we know that already though?
- Seed-borne fungi on genebank-stored cruciferous seeds from Japan. There’s lots of them. And something needs to be done about it.
- Delivering drought tolerance to those who need it; from genetic resource to cultivar. In making synthetic wheat, you can fiddle with the AB as well as the D genomes, but then you have to phenotype properly under target stress conditions, and have a way of tailoring the resulting global public goods to local needs.
- The Effects of Agricultural Technological Progress on Deforestation: What Do We Really Know? Not as much as we thought we did.
- Large-scale trade-off between agricultural intensification and crop pollination services. Intensification bad for pollinators in France, so bad for agricultural productivity and stability.
- Achieving production and conservation simultaneously in tropical agricultural landscapes. Intensification good for smallholder income in Uganda, bad for birds. If only birds were pollinators.
Nibbles: Uncommon grains, Wheat model, Yield gains, Cheese bugs, Grapes, Bee biodiversity, Pakistan seed industry, Bangladesh nutrition, Baobab juice
- Could teff or millets topple wheat, maize and rice? Anyone for unintended consequences?
- Not if superior models lead to bigger wheat harvests. ’Cos that’s all it takes.
- That and a good book: Yield Gains in Major U.S. Field Crops.
- Did somebody mention models? Vorarlberger Bergkäse is a model cheese, and “The rind is the boundary layer between a cheese and its environment”. Welcome to the cheese microbiome.
- What’s the difference between a wine grape and a table grape? Simple: Pectic-{beta}(1,4)-galactan, extensin and arabinogalactan-protein epitopes.
- Bee biodiversity results in mo’ bigger blueberries. Now to make use of that.
- Seed policy wonks – you know who you are – will thrill to IFPRI’s new report: The seed industry in Pakistan.
- So how does that square with the Financial Express of Bangladesh’s discovery that “Agro biodiversity can improve nutrition and health”?
- How to make baobab juice. Time to edit those factsheets.
Brainfood: Niche and range limits, Grassland diversity drivers, Pollinator research bias, Livestock systems, Seed longevity gene, Apple origins, Amaranthus in Mexico, Chinese medicinal orchids, Seed longevity, Fitness tradeoffs, Lentil evaluation
- Are species’ range limits simply niche limits writ large? A review of transplant experiments beyond the range. Meta-analysis shows dispersal constrains geographic distribution but extends altitudinal. Biotic interactions important at low elevations and latitudes.
- Herbivores and nutrients control grassland plant diversity via light limitation. Nutrients bad, herbivores good for grassland diversity.
- Economic and ecological implications of geographic bias in pollinator ecology in the light of pollinator declines. Half the data come from 5 countries. Nuff said.
- Integrated crop and livestock systems in Western Europe and South America: A review. Market logic has driven crops and livestock apart, but it should drive them back together again.
- ARABIDOPSIS THALIANA HOMEOBOX25 Uncovers a Role for Gibberellins in Seed Longevity. Seed longevity gene found. No word on whether giberellin treatment can prolong seed life in genebanks. Yet.
- Molecular-level and trait-level differentiation between the cultivated apple (Malus×domestica Borkh.) and its main progenitor Malus sieversii. Status of M. sieversii as main progenitor confirmed. Always good to have more data.
- Adaptation of Cultivated Amaranth (Amaranthus spp.) and Their Wild Relatives in Mexico. One of the wild species could be a source of adaptation for the cultivated under climate change.
- Eat your orchid and have it too: a potentially new conservation formula for Chinese epiphytic medicinal orchids. Nature reserves and cultivation on farms not enough. What you need is “restoration-friendly cultivation.”
- A continental-scale study of seed lifespan in experimental storage examining seed, plant, and environmental traits associated with longevity. Australian seeds are somewhat longer-lived than those from other regions. But there’s plenty of variation, some of which can be explained by different features of the seeds, plants and the specific environment where they grow.
- Inclusive fitness in agriculture. Plants and their root symbionts can get along even better together, with a little help from human selection.
- Genetic diversity analysis for quantitative traits in lentil (Lens culinaris medik.) germplasm. NBPGR seem to be on an evaluation blitz. More power to them. Hope to see the data online soon.
Nibbles: Rural income sources, Medicinal trees, Saffron, Biofuel trees, Trout genome, Maize & drugs in Mexico, Bee-keeping, Urban ag, Food security, Jackfruit, SDG2015
- Natural areas just as important for rural incomes as crops.
- Because of things like medicinal plants, among others.
- Not if the crop was saffron, though. Or multi-purpose biofuels?
- Trout gets the genome treatment. I prefer it grilled with a little butter and parsley.
- High maize prices good for one thing. Wanna guess?
- Guerrilla bee-keepers in the Rust Belt.
- Maybe they’ll be discussed in tomorrow’s tweetathon: Urban Food Security +SocialGood.
- Brussels sprouts too, maybe: it’s urban agriculture, Jim, but not as we know it.
- Another view on NatGeo’s five steps to food security. (Here’s Luigi’s.)
- The key thing NatGeo left out: jackfruit.
- Well, that, and multi-stakeholder partnerships. Of course.
Nibbles: Tomato colour, INBio demise, Specimens, Plant lore, Ancient chickens, Edible flowers, Urban veg, Trees & nutrition
- Deconstructing the colour of tomatoes. h/t @kctomato
- INBio folds? Or (h/t Jacob) government takes responsibility?
- Discussion on whether natural history specimens are necessary.
- So there’s a place where you can record your plant lore. No word on whether that’s linked to specimens.
- Yellow skin in chickens is a recent trait. Specimens involved. Part of that PNAS special feature on domestication.
- What have bees ever done for us?
- Edible flowers not just for pansies.
- Australia funds World Veg to research urban veg in Africa.
- Remember how we included in Brainfood a few months back a paper linking tree cover with dietary diversity and fruit/veg consumption in Africa? Well, here’s the PowerPoint.
