- 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?
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.
Nibbles: Gulf garden, Lettuce evaluation, Jordanian olive, Kenyan seeds, Hybrid animals, FAOSTAT news
- Qatari botanic garden is providing training in food security, and more. Good for them.
- The European Evaluation Network’s lettuce boffins have themselves a meeting. Pretty amazing this made it to FreshPlaza, and with that headline.
- The Jordan Times pretty much mangles what is a perfectly nice, though inevitably nuanced, story about the genetic depth of Jordan’s olives.
- In Kenya’s seed system, whatever is not forbidden in proposed new legislation…may not be enough.
- Conservation through hybridization.
- FAOSTAT now has a bit that gives you access to national agricultural census data. Which sounds quite important but give us a few days to check it.
Nibbles: Access to seeds indeces, Rare plants genebank, Maize and climate change, Bogota market
- So there’s an African Seed Access Index whose relationship with the Access to Seeds Index is unclear.
- The Pacific Northwest has a genebank called the Miller Seed Vault whose relationship with the National Laboratory for Genetic Resources Preservation in Fort Collins, Colorado is quite clear.
- The relationship between climate change and changes in crop distributions is becoming clearer, and more worrying.
- What is the relationship between huge markets such as Samper Mendoza in Bogota and plant conservation?
Brainfood: Insect biodiversity, Pollinator conservation, Sustaining protected areas, Tea gardens, Sustainable meat hunting, Eating weeds in Crete, Organic ag in Sweden, New wine grape varieties, Genomic crop improvement, Anthocyanins in crops, Amaranthus core collection, Bere barley
- Agriculture and climate change are reshaping insect biodiversity worldwide. Does that mean there won’t be enough of them for us to eat? Well, and to pollinate stuff I guess.
- From science to society: implementing effective strategies to improve wild pollinator health. It’s the indirect drivers that will get them in the end.
- Sustainable protected areas: Synergies between biodiversity conservation and socioeconomic development. Empower communities and management, you fools!
- Tea–vegetable gardens in Longsheng Nationalities Autonomous County: temporal and spatial distribution, agrobiodiversity and social–ecological values. Communities and management were presumably fully empowered.
- WILDMEAT interventions database: A new database of interventions addressing unsustainable wild meat hunting, consumption and trade. Very empowering, I’m sure. Unclear whether edible insects are included though.
- Chorta (Wild Greens) in Central Crete: The Bio-Cultural Heritage of a Hidden and Resilient Ingredient of the Mediterranean Diet. Well, frankly, who needs insects when you have weeds?
- Relative yield of food and efficiency of land-use in organic agriculture – A regional study. If the best bits of Sweden went fully organic, 130% more land would be needed. Unclear whether eating either weeds or insects was factored into the calculations.
- Advancing designer crops for climate resilience through an integrated genomics approach. Forget eating weeds, protecting pollinators and empowering this or that, thrown everything at crop improvement.
- Developing Germplasm and Promoting Consumption of Anthocyanin-Rich Grains for Health Benefits. Especially crops with coloured grains.
- The World Vegetable Center Amaranthus germplasm collection: Core collection development and evaluation of agronomic and nutritional traits. Well, and vegetables, presumably.
- Consumer acceptance of fungus-resistant grape wines: Evidence from Italy, the UK, and the USA. Ah yes, but whether consumers like the idea of grape vines improved through interspecific hybridization depends on what exactly you tell them. So much for empowerment.
- The evolutionary relationship between bere barley and other types of cultivated barley. Unfortunately this paper did not come out in time for the inclusion of a subplot on the introduction of Viking barley to the Orkneys in the current blockbuster The Northman. But I hear there’s stuff in there about empowerment.
