- Antiglycation activity of Vaccinium spp. (Ericaceae) from the Sam Vander Kloet collection for the treatment of type II diabetes. The tropical ones are better. But who is Sam Vander Kloet, I hear you ask?
- Genetic diversity and differentiation of grafted and seed propagated apricot (Prunus armeniaca L.) in the Maghreb region. Well, there really isn’t much.
- Trees and/or networks to display intraspecific DNA sequence variation? And.
- Below-ground plant species richness: new insights from DNA-based methods. Theory says it will be higher than above-ground richness.
- New Insight into the History of Domesticated Apple: Secondary Contribution of the European Wild Apple to the Genome of Cultivated Varieties. No genetic bottleneck, and lots of contribution from local wild relative, making European apples closer to that than to Central Asian ancestor.
- Viability of Oryza sativa L. seeds stored under genebank conditions for up to 30 years. Genebanks work.
- Barrier analysis detected genetic discontinuity among Ethiopian barley (Hordeum vulgare L.) landraces due to landscape and human mobility on gene flow. Barriers to human movement, rather than mere distance, lead to genetic differentiation in barley.

- The commodisation of quinoa: the good and the bad. Ah, that pesky Law of Unintended Consequences, why can we not just repeal it?
- No doubt there are some varieties of quinoa in Chile’s new catalog of traditional seeds. Yep, there are!
- Well, such a catalog is all well and good, but “[o]ne of the greatest databases ever created is the collection of massively diverse food genomes that have domesticated us around the world. This collection represents generation after generation of open source biohacking by hobbyists, farmers and more recently proprietary biohacking by agronomists and biologists.”
- What’s the genome of a spleen sandwich, I wonder?
- And this “marine snow” food for eels sounds like biohacking to me, in spades.
- But I think this is more what they had in mind. Grand Challenges in Global Health has awarded Explorations Grants, and some of them are in agriculture.
- Wanna help ILRI with its biohacking? Well go on then.
- Digging up ancient Chinese malarial biohacking.
- Digging up Thomas Jefferson’s garden. Remember Pawnee corn? I suppose it’s all organic?
- The Mediterranean diet used to be based on the acorn. Well I’m glad we biohacked away from that.
- How barley copes with extreme day length at high latitudes. Here comes the freaky biohacking science.
- Why working out what is the world’s rainiest place is not as easy as it sounds. But now that we know, surely there’s some biohacking to be done with the crops there?
Prospects for fish (and other) farming
The CGIAR Research Program on Aquatic Agricultural Systems launched recently with this video of what research can do for poor families in Bangladesh, and yes, they’re big on agricultural biodiversity. All they need to do now is stop sea-levels rising …
Nibbles: Kenyan blog, Beer, CGIAR squared, Horse domestication
- And Kenya’s best agriculture blog is…Tracking The Scent! Congrats Kio Wachira!
- Drinking beer as an agricultural act.
- CRP4 needs a new name.
- Meanwhile, here’s another example of CGIAR centres working together. Not clear if it’s in a CRP, though, and if so what it is called.
- Horse domesticated once, but with occasional restocking.

- Species vulnerability to climate change: impacts on spatial conservation priorities and species representation. Yes, you can focus on sensitive species, but it comes at the cost of representativeness.
- Estimating management costs of protected areas: A novel approach from the Eastern Arc Mountains, Tanzania. Those are $ costs per pixel on the map, which I’ve never seen before. Don’t think they took into account the effects of climate change, though. Maybe they should get in touch with the Aussies above?
- The use of mycorrhizal inoculation in the domestication of Ziziphus mauritiana and Tamarindus indica in Mali (West Africa). It would help.
- A new integrative indicator to assess crop genetic diversity. Includes varietal richness, spatial evenness, between-variety genetic diversity, and within-variety genetic diversity. Not much left, really. Anyway, remember this from last week? Anyone out there going to put 2 and 2 together?
- Assessing Nutritional Diversity of Cropping Systems in African Villages. A new tool! Different from the integrative indicator above! Anyone going to put 4 and 2 together?
- Agriculture-Nutrition Pathways Recognising the Obstacles. “The pathways between agriculture and nutrition seem to be laden with impediments, particularly in the form of intricate household preferences.” Those pesky preferences.
- The chestnut blight fungus world tour: successive introduction events from diverse origins in an invasive plant fungal pathogen. Asia to N. America to Europe, but more than once. All very complicated. The surprising thing is that low diversity and low admixture have nevertheless still resulted in success in disparate places. What fiendish molecular or biochemical mechanism is behind this? Only more research will show, natch.
- Translocation of wild populations: conservation implications for the genetic diversity of the black-lipped pearl oyster Pinctada margaritifera. Introducing some wild individuals near farms leads to more diverse farmed populations, right? Nope. The farmed populations are way diverse already and if anything the diversity is moving the other way.
- Maize x Teosinte Hybrid Cobs Do Not Prevent Crop Gene Introgression. That’s because the hybrid cobs break apart much more easily than maize.
- Detecting population structure and recent demographic history in endangered livestock breeds: the case of the Italian autochthonous donkeys. Microsatellites confirm existence of 8 breeds of Italian donkey, though there is also significant substructuring within each by farm. This apparently calls for a “synergic management strategy at the farm level,” which basically means using the breed as the unit of conservation but being careful about inbreeding.
- Evolutionary tools for phytosanitary risk analysis: phylogenetic signal as a predictor of host range of plant pests and pathogens. Work out host susceptibility by looking at existing pest preferences and phylogenetic distance from the stuff the pest is known to like.
