- Evolution of the crop rhizosphere: impact of domestication on root exudates in tetraploid wheat (Triticum turgidum L.). Domestication and breeding have led to (probably adaptive) changes in root exudates.
- Threats from urban expansion, agricultural transformation and forest loss on global conservation priority areas. Vertebrate Biodiversity Hotspots are most threatened by all three factors. Plants too?
- Patterns and drivers of biodiversity–stability relationships under climate extremes. Species richness may not be enough to buffer ecosystems from extreme precipitations events. But a different metric would give a different result?
- Evaluating the environmental impacts of dietary recommendations. Adopting nationally recommended diets would help the environment.
- On the Use of Hedonic Price Indices to Understand Ecosystem Service Provision from Urban Green Space in Five Latin American Megacities. There’s an overall strong positive correlation between urban greenery and house prices, but it’s context-specific.
- Disease: A Hitherto Unexplored Constraint on the Spread of Dogs (Canis lupus familiaris) in Pre-Columbian South America. Yes, why are there no dogs in the Amazon?
- Children and Wild Foods in the Context of Deforestation in Rural Malawi. Fewer wild foods in more deforested sites, and fewer sold by children from better-off households. What of the nutrition outcomes, though?
- Biodiversity defrosted: unveiling non-compliant fish trade in ethnic food stores. About 40% of samples in Liverpool and Manchester mislabelled.
- Population viability analysis of the Crioula Lageano cattle. It’s going to be fine.
- The Kalanchoë genome provides insights into convergent evolution and building blocks of crassulacean acid metabolism. Next stop, CAM rice.
- Contribution of trees to the conservation of biodiversity and ecosystem services in agricultural landscapes. It depends. But what would those kids in Malawi say?
European parliamentarians get to grips with crop wild relatives
A European Parliament committee discussing “Genetic diversity, conservation and crops wild relatives”? Yeah, I didn’t think that was possible either, but here’s the evidence. And you can even see and hear the whole thing, in the language of your choice. 1 In the hot seat in front of the committee were: Prof. Nigel Maxted, Senior Lecturer in Genetic Conservation, School of Biosciences, University of Birmingham, UK; Dr Susanne Barth, Senior Research Officer, Plant Genetics, Teagasc CELUP Crop Research, Ireland; and Dr Nicolas Roux, Senior Scientist, Musa Genetic Resources Team Leader, Effective Genetic Resources Conservation and Use Initiative, Bioversity International, Montpellier, France.
At least one parliamentarian was impressed with what Nigel (right) et al. had to say. Let’s hope that translates into action.
Fascinating session in @EP_Agriculture on Genetic Diversity and Crop Wild Relatives. Dr Nigel Maxted from @birminghamuniv talking about threats to genetic diversity and importance of conserving wild plant species, “we cannot wait we have to conserve them now” pic.twitter.com/Uw8UkySDDa

Nibbles: Orphan edition
- The Economist jumps on the genomics-for-orphan-crops bandwagon.
- But is phenomics more important?
- And seed systems, don’t forget seed systems…
- Some of those orphan crops may get an International Day, if India has anything to do with it.
- Immortelle is as orphan as they come, but maybe not in Croatia any more.
- Amaranthus never really went away, not in Mexico.
- Persimmon, meanwhile, is being adopted by the snack industry in the US. But the Japanese are way ahead.
- Some think yerba mate is not orphan enough.
- Is yam an orphan. It depends on what your definition of is is.
- Avocado is the opposite of orphaned in Mexico. It is spoiled rotten.
- Many orphan crops are women’s crops. Case in point: enset.
- Orphan is a relative term, and reversible.
- Exhibit B: sweet potato.
- People often take their orphan crops with them. Even in antiquity.
- Coconut is fast becoming an orphan in Tanzania.
- With 32 cultivars available to grow in Louisiana alone, nobody can say lettuce is an orphan.
- Mexico and Brazil collaborate on crop diversity conservation. Including orphan crops?
- One thing that is probably not a huge priority for orphan crops is their wild relatives. Just saying.
- Anyway, we’re going to need all the orphan crops we can get if James Cameron’s titanic vegetarian utopia is to come true.
Brainfood: Setaria diversity, Planteome, Cowpea diversity, Fertile Crescent CWR, Beer flavour, Marula diversity, Wild dates
- Genetic Structure of Foxtail Millet Landraces. China is the centre of diversity, and diversity structured geographically there.
- The Planteome database: an integrated resource for reference ontologies, plant genomics and phenomics. A sort of ontology of ontologies.
- Genetic diversity and structure of Iberian Peninsula cowpeas compared to world-wide cowpea accessions using high density SNP markers. Iberian material all falls into 1 (S Europe-N Africa) of 4 worldwide groups.
- Setting conservation priorities for crop wild relatives in the Fertile Crescent. 220 priority species.
- Effects of Barley (Hordeum vulgare L.) Variety and Growing Environment on Beer Flavor. It’s not just the hops.
- Molecular Characterization of Sclerocarya birrea ICRAF Field Genebank Collections. Even the duplicates identified could be good for something.
- The Domestication Syndrome in Phoenix dactylifera Seeds: Toward the Identification of Wild Date Palm Populations. Fancy maths shows there may be actual wild date palms in Oman.
Brainfood: Coffee apocalypse, Barley journey, Haplotype cores, Pollinator conservation, Rooting for tubers, Aussie CWR, European veggies, Capsicum evolution, Wheat genome
- Climate change adaptation of coffee production in space and time. There’s a plan, at least for Nicaragua.
- Journey to the east: Diverse routes and variable flowering times for wheat and barley en route to prehistoric China. Growing in diverse environments pre-adapted barley for its shift to spring sowing and move eastwards to China.
- Capturing haplotypes in germplasm core collections using bioinformatics. Fortunately, “the number of accessions necessary to capture a given percentage of the haplotypic diversity present in the entire collection can be estimated.”
- Pollinator Diversity: Distribution, Ecological Function, and Conservation. 350,000 species!
- Roots, Tubers and Bananas: Planning and research for climate resilience. Much the same, but faster.
- Priorities for enhancing the ex situ conservation and use of Australian crop wild relatives. Go north, young woman.
- Consequences of climate change for conserving leafy vegetable CWR in Europe. Go, err, northwest.
- Phylogenetic relationships, diversification and expansion of chili peppers (Capsicum, Solanaceae). Monophyletic clade which originated along the Andes of W to NW South America and spread clockwise around the Amazon.
- The Aegilops tauschii genome reveals multiple impacts of transposons. The D genome bites the dust.
