- The genomic signature of wild-to-crop introgression during the domestication of scarlet runner bean (Phaseolus coccineus L.). The wild Mexican genepool is helping to counteract the effects of the domestication bottleneck.
- Genetic variation in wild and cultivated Arabica coffee (Coffea arabica L.): Evolutionary origin, global distribution, and its effect on fungal disease incidence in Southwest Ethiopia. Domesticated disease-resistant cultivars are threatening the genetic integrity of the wild genepool. You win some, you lose some.
- Uncovering haplotype diversity in cultivated Mexican vanilla species. Plenty of evidence of past hybridization events in cultivated vanilla in Mexico. Maybe it can swap stories with scarlet runner bean.
- Six-rowed wild-growing barleys are hybrids of diverse origins. In the case of barley, the wild-cultivated hybrids even got a separate Latin binomial.
- Portrait of a genus: genome sequencing reveals evidence of adaptive variation in Zea. Lots of variation in interesting adaptive traits in the wild relatives of maize. Did they, or will they, make their way into the crop, I wonder?
- An adaptive teosinte mexicana introgression modulates phosphatidylcholine levels and is associated with maize flowering time. This one did.
- A highly conserved core bacterial microbiota with nitrogen-fixation capacity inhabits the xylem sap in maize plants. Its wild relatives are not the only wild organisms maize benefits from.
- Phenomic data-facilitated rust and senescence prediction in maize using machine learning algorithms. Drones and fancy maths can be used to predict and document southern rust infection in maize. Maybe in wild relatives too one day, who knows.
- A Solanum lycopersicoides reference genome facilitates insights into tomato specialized metabolism and immunity. A tomato wild relative has a gene for resistance to bacterial speck disease, so of course they had to sequence its genome.
- Genetic gains in potato breeding as measured by field testing of cultivars released during the last 200 years in the Nordic Region of Europe. Genetic gains for yield (measured in non-target environments) were not that great and contributed about half of productivity gains. Results for other traits were even worse, mainly because of stringent market demands. So no chance of using wild relatives I suppose.
- Genotypic Response and Selection of Potato Germplasm Under Heat Stress. Not so fast…
- Dataset of historic and modern bread and durum wheat cultivar performance under conventional and reduced tillage with full and reduced irrigation. I wonder to what extent wild relatives contributed to the differences.
- Assessing returns to research investments in rice varietal development: Evidence from the Philippines and Bangladesh. Net returns from collaboration in rice breeding between IRRI and national partners are still strong in the Philippines and Bangladesh, but declining, and faster in the former than the latter. Plenty of genes from wild relatives in IRRI lines of course. Maybe there could be more?

- Biodiversity and yield trade‐offs for organic farming. Switch to organic agriculture if the surrounding land that will need to be converted to farming to make up for production shortfalls is less than 2.4 times more biodiverse than the farmed land. But that’s an average that will depend on the crop.
- Global wheat production could benefit from closing the genetic yield gap. Customize improved wheat varieties to local conditions by using the diversity in genebanks. No word on whether that includes organic conditions.
- The impact of the international rice genebank (IRG) on rice farming in Bangladesh. Someone mention genebanks? 1% increase in genebank contribution to new variety means 1% increase in yield. No word on what happens under organic conditions.
- Constraints on Rice Cultivation in Eastern Madagascar: Which Factors Matter to Smallholders, and Which Influence Food Security? Does swidden cultivation count as organic?
- What are the links between tree-based farming and dietary quality for rural households? A review of emerging evidence in low- and middle-income countries. It’s generally a good idea to keep trees around your farm. But how to make sure that it happens?
- Transforming food systems with trees and forests. Here’s how: scale up tree food production, reorient research towards trees foods, repurposing production incentives towards tree foods, and integrate nutrition with conservation. Got it? No word on whether the whole thing needs to be organic though.
- High exposure of global tree diversity to human pressure. But what about the diversity of trees on farms? Well I guess if we do the above properly it will be ok.
- Carbon removals from nature restoration are no substitute for steep emission reductions. Trees are not enough.
Nibbles: Pacific genebank, IPBES report, New mangoes, British apples, Greek landraces, Fonio, Space seeds, Macadamia cryo
- New Zealand supports SPC regional crops and trees genebank in a big way.
- Some of those trees are wild species that contribute to food security, and more must be done to conserve them.
- Some trees are crops of course, like mangoes, and scientists are doing their bit for them in the Philippines.
- Wait, isn’t it too early for the usual BBC saving-the-apple story? Usually comes in the autumn.
- Who needs genebanks when you can inscribe landraces in a National Inventory of Intangible Cultural Heritage.
- Maybe try it with fonio next?
- Or just send seeds into space?
- Maybe including macadamia, or is space not cold enough for them?

- Long-term evidence for ecological intensification as a pathway to sustainable agriculture. Meta-analysis of 30 long-term experiments from Europe and Africa comprising 25,565 data points shows that increasing crop diversity and adding fertility crops and organic matter are as good for the yield of staple crops as N fertilization, but don’t add much if you already have the latter, and vice versa.
- Revisiting the adequacy of the economic policy narrative underpinning the Green Revolution. If only the Green Revolutionaries had know the above, eh? Anyway, remember institutions, people.
- Agroecological practices increase farmers’ well-being in an agricultural growth corridor in Tanzania. Higher awareness of the benefits of nature plus more engagement with extension services mean more adoption of agroecological practices means farmers are better off. Green Revolutionaries unavailable for comment. Institutions rejoice.
- Intangible links between household livelihoods and food security in Solomon Islands: implications for rural development. Diversifying livelihoods isn’t always associated with better food security.
- Access to and Utilization of Wild Species for Food and Nutrition Security in Teso and Acholi Sub-regions of Uganda. Wait, does the above mean that decreasing access to wild foods may not necessarily matter? Why does this stuff have to be so hard?
- Climate Change and Seed System Interventions Impact on Food Security and Incomes in East Africa. More crop diversity on farms “helps farmers cope with climate change and increases productivity, food availability, incomes and food security.” Not so hard after all.
- Welfare impacts of improved groundnut varieties adoption and food security implications in the semi-arid areas of West Africa. Adopting new peanut varieties is good for farmers. Wait, so the opposite of more crop diversity? Why does this stuff have to be so hard?
- Situating Plant Genetic Resource in the K-12 Curriculum: A Critical Review. Maybe we should all go back to school.
