- 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?

- Blaming organic agriculture for Sri Lanka’s woes is a little…simplistic.
- Deriding food localism as luddite is a little…simplistic. I wonder if there will be a rural re-exodus in Sri Lanka.
- Pigeonpea is back on the menu in Malawi. Organically produced, no doubt.
- Will it be closely followed by sorghum and millet in Zimbabwe?
- Brazil puts together a vanilla collection. Because you can only go so far on sorghum and pigeonpea.
- Meanwhile, “…China Has Become the World’s Largest Funder of Agricultural R&D,” displacing the US. Including local and organic ag, pigeonpea and sorghum? I wonder…
- Looks like jujube might be an example of US-China collaboration on ag research. Maybe.

- Agricultural trade and its impacts on cropland use and the global loss of species habitat. Rich countries have a large biodiversity footprint outside their borders because they import a lot of agricultural products from areas where biodiversity is disappearing fast.
- International food trade benefits biodiversity and food security in low-income countries. Ah, but low-income, high biodiversity countries import a lot too. I really don’t know what to think about trade now. Nicely parsed by Emma Bryce.
- Biodiversity and yield trade-offs for organic farming. Biodiversity gain and yield loss balance each other out. Oh, come on scientists, would it kill you to give a definite answer?
- Crop harvests for direct food use insufficient to meet the UN’s food security goal. We should definitely use more cropland for actual human food. But that would probably not be good for exports, no? Uff.
- The hidden safety net: wild and semi-wild plant consumption and dietary diversity among women farmers in Southwestern Burkina Faso. Yeah, but who needs crops and imports anyway.
- Six decades of warming and drought in the world’s top wheat-producing countries offset the benefits of rising CO2 to yield. In any case, crops are in trouble.
- Planning complementary conservation of crop wild relative diversity in southern Africa. But CWR will save crops if only we can conserve them.
- Genome Editing for Sustainable Agriculture in Africa. Especially if we use the latest toys.
- Impact of the European Union’s Seed Legislation and Intellectual Property Rights on Crop Diversity. And have all the right policies in place.
- Farm-level production diversity and child and adolescent nutrition in rural sub-Saharan Africa: a multicountry, longitudinal study. But actually, it’s livestock we really need.
