- 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?
Nibbles: Organic ag, Local ag, Pigeonpea, African cereals, Vanilla genebank, Ag R&D, Ziziphus
- 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.
Brainfood: Rice domestication, Roman wine, Dog domestication, Earth ovens, Forest orchards, Saffron origins
- The Fits and Starts of Indian Rice Domestication: How the Movement of Rice Across Northwest India Impacted Domestication Pathways and Agricultural Stories. While cultivation of (indica) rice in South Asia began in the Ganges around 6500 BC, its domestication really speeded up 3000 years later in the Indus.
- Archaeobotanical and chemical investigations on wine amphorae from San Felice Circeo (Italy) shed light on grape beverages at the Roman time. In the second century BC the ancient Romans may have traded a medicinal wine made from wild or semi-domesticated grapevines. I wonder how it would have gone with a nice risotto.
- Grey wolf genomic history reveals a dual ancestry of dogs. Either dogs were domesticated independently in E and W Eurasia and then the two lineages merged, or they were domesticated in the E and then there was geneflow from wild dogs. Sounds a bit like rice actually. ((No, really, check it out. Japonica gets domesticated in one place, then taken to another place where it gets into geneflow with indica, which is being domesticated elsewhere. Only difference is that 2 different wild species are involved, rather than just a single wild wolf species. Also maybe echoes of what happened in tomato too?))
- Bulbs and Biographies, Pine Nuts and Palimpsests: Exploring Plant Diversity and Earth Oven Reuse at a Late Period Plateau Site. For 2000 years Native Americans returned to specific food processing sites dug into the soil to cook up a storm. No word on the use of wild grapevines.
- Coupled archaeological and ecological analyses reveal ancient cultivation and land use in Nuchatlaht (Nuu-chah-nulth) territories, Pacific Northwest. Native Americans nurtured forest gardens to enrich them with edible species. Including wild apples though again not wild grapevines apparently.
- Ancient Artworks and Crocus Genetics Both Support Saffron’s Origin in Early Greece. Ok now everything is in place for a nice risotto alla Milanese with a Falanghina at the House of the Tragic Poet.
Podcasting agricultural biodiversity
Talking of agrobiodiversity-themed podcasts ((Yes, we were, kinda.)), there’s a fun dip into (some of the) history of the tomato over at Historically Thinking. Meanwhile, at Eat This Podcast, Jeremy has embarked on a monumental romp ((Yes, you can have a monumental romp.)) through the role of wheat in world history. Pizza, anyone?
Nibbles: Ag & biodiversity, Sattu, African crops, New rice, Maya religion
- Good roundup of the latest thinking on land sharing vs sparing.
- Hummus is not the only thing to use chickpeas for: you can also make sattu sherbert.
- Africa looks to fonio. Again.
- A new, uniquely high-protein, low-glycemic index rice.
