- Cannabis Domestication, Breeding History, Present-day Genetic Diversity, and Future Prospects. The weed is in trouble, man. Just one of the papers in a very special issue of Critical Reviews in Plant Sciences. And for a historical perspective…
- Genomic analyses of primitive, wild and cultivated citrus provide insights into asexual reproduction. Apomixis is down to a “miniature inverted-repeat transposable element insertion in the promoter region of CitRWP.”
- Automated cropland mapping of continental Africa using Google Earth Engine cloud computing. Croplands increased by 1 Mha/yr between 2003 and 2014.

- Phylogeography of the wild and cultivated stimulant plant qat (Catha edulis, Celastraceae) in areas of historical cultivation. Centres of origin in Kenya and Ethiopia, with limited movement between the two, but some hybrids in N. Kenya; the Yemeni stuff came from Ethiopia.
- Process-based modelling shows how climate and demography shape language diversity. If you assume human groups split after reaching a certain population size, and rainfall limits population density, you can predict language diversity in Australia.
- Volatile Compound Profiles of Malus baccata and Malus prunifolia Wild Apple Fruit. Look at the esters.

Nibbles: Treaty & UPOV, Minor millets redux, Maize replacement, Amaranth et al., Squash story squashed, Potato podcast, Food security webinar, Plants Day, Repast magazine, German beer, Coffee strategy, ILRI genebank
- The ITPGRFA and UPOV need to sort out their connection.
- Bring back our millets.
- And our sorghum and pigeonpeas too.
- And the milpa.
- And speaking of milpa crops, the real story of that large, old squash.
- Since we’re at it, bring back the potato too. To the people.
- Yet another interesting webinar which I missed. Wonder whether they talked about the above. Anyone?
- Still have time to prepare for “Fascination of Plants Day” on 18 May 2017, though.
- Repast: “the First-Ever Food History Magazine”. ‘Nuff said.
- Gotta love those German purity laws.
- A strategy for conserving coffee genetic resources takes shape. Now for the money…
- New forages genebank opens at ILRI in Ethiopia.
Brainfood: Tomato chemicals, Photoperiod, Grain phenotyping, Hawaiian ag, Domestication primer, Symbionts, Turkish wheat, Yam bean diversity, Crop health, Walnut diversity, Agrobiodiversity theorising, Sea pigs, NERICA impacts, Nutrient production
- Multi-perspective evaluation of phytonutrients – Case study on tomato landraces for fresh consumption. Fancy maths proves different tomato varieties taste different.
- Adaptation to the Local Environment by Modifications of the Photoperiod Response in Crops. It’s all down to a few mutations in all crops.
- Evaluation of the SeedCounter, A Mobile Application for Grain Phenotyping. Seems like a lot of work to just be able to measure wheat seeds, but boys will have their toys.
- Indigenous Polynesian Agriculture in Hawaiʻi. Both intensive and extensive.
- How to make a domesticate. It takes a long time, and involves lots of genes.
- Symbiosis limits establishment of legumes outside their native range at a global scale. Non-symbiotic legumes have spread further than symbiotic ones into non-native areas.
- Wheat Landraces Currently Grown in Turkey: Distribution, Diversity, and Use. More than half of morphotypes (59%) lost since 1920 overall, but none in some areas.
- Ecotypic differentiation under farmers’ selection: Molecular insights into the domestication of Pachyrhizus Rich. ex DC. (Fabaceae) in the Peruvian Andes. Separate Amazonian and Andean lineages, and P. tuberosum arising from P. ahipa.
- Crop health and its global impacts on the components of food security. To better understand acute impacts, model systemic ones.
- Climate-Related Local Extinctions Are Already Widespread among Plant and Animal Species. About half of about 1000 species showed local extinction.
- Rethinking the history of common walnut (Juglans regia L.) in Europe: Its origins and human interactions. Expansion from glacial refugia, followed by human exploitation. Compare and contrast with Asia. Or read about the whole thing in AramcoWorld.
- Agrobiodiversity and a sustainable food future. Apparently all you need to do to support the “use of biological diversity in sustainable agricultural and food systems” is to recognize that there are 4 interconnected themes: (1) genetic resources, ecology and evolution; (2) governance policy, institutions and legal agreements; (3) food, nutrition, health and disease; and (4) global change drivers with social ecological interactions.
- Eastern Mediterranean Mobility in the Bronze and Early Iron Ages: Inferences from Ancient DNA of Pigs and Cattle. Anatolia to southeastern Europe and back to the Levant across the Bronze-Iron Age transition. The Sea Peoples had pigs?
- Contribution of improved rice varieties to poverty reduction and food security in sub-Saharan Africa. NERICA adoption increased annual per capita income by US$4 per year from 2000, despite yields going down a bit.
- Farming and the geography of nutrient production for human use: a transdisciplinary analysis. Need to try to maintain production diversity as farm size increases. But let Jess Fanzo explain it better.

- The Value of Biodiversity as an Insurance Device. So apparently the “Epstein-Zin-Weil specification of the utility function allows us to disentangle the effects of risk aversion and aversion to fluctuations.” Good to know.
- The Invasive Legacy of Forage Grass Introductions into Florida. Sometimes biodiversity is bad for you, Epstein-Zin-Weil specification or not.

- Genetic studies regarding the control of seed pigmentation of an ancient European pointed maize (Zea mays L.) rich in phlobaphenes: the “Nero Spinoso” from the Camonica valley. But do we really want to promote a landrace as a functional food?
- Genetic diversity patterns in ex situ collections of Oryza officinalis Wall. ex G. Watt revealed by morphological and microsatellite markers. Malesia separates out from SE Asia, and similarities between PNG and Philippines points to long-distance dispersal by birds. Or germplasm collectors.
- Perceptual selection and the unconscious selection of ‘volunteer’ seedlings in clonally propagated crops: an example with African cassava (Manihot esculenta Crantz) using ethnobotany and population genetics. Occasional seedlings are allowed to survive not so much because they look different, but because they look similar, to existing landraces, even though they may be genetically distinct.
- Evolutionary “Bet-Hedgers” under Cultivation: Investigating the Domestication of Erect Knotweed (Polygonum erectum L.) using Growth Experiments. Experimental domestication pretty quickly gets rid of that peskily bet-hedging germination heteromorphism.
