- Indirect Effect of a Transgenic Wheat on Aphids through Enhanced Powdery Mildew Resistance. Plants resistant to fungus have more aphids. Oh dear.
- A case study of seed exchange networks and gene flow for barley (Hordeum vulgare subsp. vulgare) in Morocco. There is more movement of material among villages than interviews suggest.
- Evaluation of plant-derived products against pests and diseases of medicinal plants: A review. Extracts from some medicinal plants used to protect other medicinal plants.
- Identifying key knowledge needs for evidence-based conservation of wild insect pollinators: a collaborative cross-sectoral exercise. Top one: How important is the diversity of pollinator species to the resilience and reliability of the pollination service? Seems a pretty good start.

- A Population Genomics Perspective on the Emergence and Adaptation of New Plant Pathogens in Agro-Ecosystems. Crop diversity affects fungal diversity as much as the other way around. Actually more so, as fungal genomes are incredibly plastic.
- Teosinte as a model system for population and ecological genomics. Genetics of speciation, hybridization, various evolutionary questions: all can usefully be looked at in the maize-teosinte system with cheap next-generation sequencing. Oh, and that can help us with crop improvement.
- Does organic farming reduce environmental impacts? –- A meta-analysis of European research. Per unit area, yes. Per unit product, not always. Need to mix and match. Good luck with that.
- “Healthy,” “diet,” or “hedonic”. How nutrition claims affect food-related perceptions and intake? If you tell people something is healthier, they believe it is, in fact, well, healthier.
- Guanaco management by pastoralists in the Southern Andes. They can coexist with cattle.
- Earthworms promote the reduction of Fusarium biomass and deoxynivalenol content in wheat straw under field conditions. Earthworms protect crops from pathogens.
- Screening of pea germplasm for resistance to powdery mildew. 14 accessions from 10 countries are promising. That’s out of 700. Hard row to hoe.
- Sources of high tolerance to salinity in pea (Pisum sativum L.). Out of some 780 accessions, China seems to be a hotspot, but the most tolerant accession was from Greece. Any overlap with the previous results?
- A rare case of natural regeneration in butternut, a threatened forest tree, is parent and space limited. In situ is not enough. Not if you don’t help it along, anyway.
- Relationship between survival and yield related traits in Solanum pimpinellifolium under salt stress. 2 accessions among a subset of over 90 from over 300 in the AVRDC collection show high survival and yield under stress. Would be interesting to know if the 90 were indeed well-chosen in the first place.
- Climate warming could shift the timing of seed germination in alpine plants. Spring emergence will shift to autumn, but the bad effect will be on the seedlings.
- Medieval emergence of sweet melons, Cucumis melo (Cucurbitaceae). Lexicography suggests that there were sweet melons in Central Asia early on, but they didn’t get to Iberia until the late 11th Century, and to the rest of Europe until the 15th. Climate and the clash of civilizations to blame, as ever.
- Tibet is one of the centers of domestication of cultivated barley. The other being the Fertile Crescent. Some Chinese hulless and six-rowed barleys in particular are similar to Tibetan wild material. But are the authors stretching the data?
- A map of rice genome variation reveals the origin of cultivated rice. Or origins. Japonica first domesticated from O. rufipogon in the middle Pearl River in Southern China, and indica is a hybrid of the first cultivars with local wild rice in South East and South Asia. But have we not heard this before? Ah, but this paper has more, better markers, no doubt. Anyway, compare and contrast with maize and barley above.
- Lessons on the relationship between livestock husbandry and biodiversity from the Kenya Long-term Exclosure Experiment (KLEE). Livestock and wildlife can coexist, but you have to work at it. Bit like the guanaco thing, then?
- Modeling plant species distributions under future climates: how fine-scale do climate projections need to be? Doesn’t matter for total extent, but actual locations of stable climates vary with scale. On average, “270 m is fine enough,” but it really depends on the species. Probably safest answer is “as fine as possible.”
- Fertilisers and insect herbivores: a meta-analysis. Fertilizers good for insect numbers. Which means bad for plants? But insect diversity? Wonder what they do to those earthworms and fungi above…
Brainfood: Wild barley drought tolerance, GM cassava retraction, Lupinus ploidy, Diversity levels
- SSR analysis of introgression of drought tolerance from the genome of Hordeum spontaneum into cultivated barley (Hordeum vulgare ssp vulgare). Scary thing is that only two wild accessions are involved.
- Transgenic Biofortification of the Starchy Staple Cassava (Manihot esculenta) Generates a Novel Sink for Protein. Fancy biotech puts more of a substance in cassava that nobody eats cassava for. No, wait.
- Whole genome duplication in a threatened grassland plant and the efficacy of seed transfer zones. Mixing of seed from different populations can be a good idea for conservation of rare plants, but not when they also differ in ploidy.
- Genetic diversity in widespread species is not congruent with species richness in alpine plant communities. Cannot use one as a proxy for the other.
Brainfood: Organic ag, Garlic conservation costs, Spelt malting, Wild rice genetics, Diversity and ecosystem function, Old late blight, Urbanization and biodiversity, Seed laws, DNA from herbaria, Fruit & veg & school, Quinoa bars, Maize introgression
- Organic vegetable farms are not nutritionally disadvantaged compared with adjacent conventional or integrated vegetable farms in Eastern Australia. Something for the next meta-analysis.
- Comparing costs for different conservation strategies of garlic (Allium sativum L.) germplasm in genebanks. It depends.
- Malting process optimization of spelt (Triticum spelta L.) for the brewing process. You can make a decent beer from spelt. Can I do the evaluation?
- Genetic differentiation of Oryza ruffipogon [sic] Griff. from Hainan Island and Guangdong, China Based on Hd1 and Ehd1 genes. It’s different, because of different ecology.
- Plant species diversity and genetic diversity within a dominant species interactively affect plant community biomass. In other words, the higher the genetic diversity within the dominant species, the further the effect of species diversity on biomass goes from negative to positive. Bottom line is that you have to consider multiple diversity levels in relating biodiversity to ecosystem functioning. At least in this ecosystem.
- Evidence for presence of the founder Ia mtDNA haplotype of Phytophthora infestans in 19th century potato tubers from the Rothamsted archives. “…the founder Ia mtDNA haplotype survived in potato tubers after 1846 and was present over 30 years later in the UK.”
- Global forecasts of urban expansion to 2030 and direct impacts on biodiversity and carbon pools. Urban area to triple, affecting important biodiversity hotspots. Biggest surprise to me was Turkey. Gotta be a lot of CWRs there that are going to be threatened by urbanization. But I guess this is good news for urban agriculture?
- Seed Governance at the Intersection of Multiple Global and Nation-State Priorities: Modernizing Seeds in Turkey. Developing countries are opting for laws that favor commercialization and privatization because they’re buying into the currently dominant paradigm of what agricultural development means. If they didn’t, they wouldn’t. And if my aunt had wheels she’d be a bus.
- DNA Damage in Plant Herbarium Tissue. There isn’t enough of it to matter.
- Systematic review and meta-analysis of school-based interventions to improve daily fruit and vegetable intake in children aged 5 to 12 y. Fruit yes, veggies no.
- Use of cereal bars with quinoa (Chenopodium quinoa W.) to reduce risk factors related to cardiovascular diseases. Only 22 young(ish) subjects, but promising.
- The Genomic Signature of Crop-Wild Introgression in Maize. The wild relative has helped the cultigen to adapt to highland Mexico.
Brainfood: South American threat map, Bee domestication, Rice origins, Legume diversity, Lima bean domestication
- Analysis of threats to South American flora and its implications for conservation. Bottom line: Ecuadorian and Colombian Andes, southern Paraguay, the Guyana shield, southern Brazil, and Bolivia. But don’t let that divert your attention from the cool maps.
- Management increases genetic diversity of honey bees via admixture. No genetic bottleneck there. And the same in more words, but not as many as the original paper.
- Phylogeography of Asian wild rice, Oryza rufipogon: a genome-wide view. When in doubt, throw more markers at it. Two groups in O. rufipogon, only the Chinese/Indochinese one related to cultivated rice (indica). Japonica out on a limb. And the longer version.
- Legume Diversity Patterns in West Central Africa: Influence of Species Biology on Distribution Models. Temperature variables are most important.
- Multiple domestications of the Mesoamerican gene pool of lima bean (Phaseolus lunatus L.): evidence from chloroplast DNA sequences. Andean and Mesoamerican cultivated genepools confirmed, and two sub-genepools within the latter, one originating in western central Mexico and the other between Guatemala and Costa Rica. Will they mash up with the study in the first link? Some of the people involved are neighbours and friends.
