Brainfood: Maize, Chickpea, CWR, Canola, Coconut, Avocado, Eggplant, Carrot, Watermelon, Citrus, Potato, Pearl millet, Roses
- A New Methodological Approach to Detect Microcenters and Regions of Maize Genetic Diversity in Different Areas of Lowland South America. Multiple disciplines identify 4 microcenters of maize diversity in the lowlands of South America.
- Historical Routes for Diversification of Domesticated Chickpea Inferred from Landrace Genomics. Genomics identifies both Indian and Middle Eastern traces in Ethiopian chickpeas.
- Crop wild relatives in Lebanon: mapping the distribution of Poaceae and Fabaceae priority taxa for conservation planning. Spatial analysis identifies a couple of key ex situ and in situ conservation areas for CWR in Lebanon.
- Analysis of gaps in rapeseed (Brassica napus L.) collections in European genebanks. Spatial analysis identifies a few key ex situ and in situ conservation areas for rapeseed wild relatives in Europe.
- Genomic and population characterization of a diversity panel of dwarf and tall coconut accessions from the International Coconut Genebank for Latin America and Caribbean. Characterization of various sorts identifies different Atlantic and Pacific coconut genepools in the Western Hemisphere.
- Pleistocene-dated genomic divergence of avocado trees supports cryptic diversity in the Colombian germplasm. Genomics identifies a uniquely Colombian avocado genepool.
- Analysis of >3400 worldwide eggplant accessions reveals two independent domestication events and multiple migration-diversification routes. Genomics identifies separate Southeast Asia and Indian areas of domestication, and limited exchange between them.
- Population genomics identifies genetic signatures of carrot domestication and improvement and uncovers the origin of high-carotenoid orange carrots. Genomics identifies wester-central Asia as the area of carrot domestication in the Early Middle Ages, and western Europe as the place where the orange variant was selected in the Renaissance.
- A Citrullus genus super-pangenome reveals extensive variations in wild and cultivated watermelons and sheds light on watermelon evolution and domestication. Pangenomics identifies a gene in wild Kordofan melons as promoting the accumulation of sugar in watermelon.
- Pangenome analysis provides insight into the evolution of the orange subfamily and a key gene for citric acid accumulation in citrus fruits. Pangenomics identifies south central China as the primary centre of origin of the genus Citrus.
- Pangenome analyses reveal impact of transposable elements and ploidy on the evolution of potato species. Pangenomics identifies wild species from North and Central America as having lots of genes for abiotic stress response, but also fewer transposable elements.
- Pangenomic analysis identifies structural variation associated with heat tolerance in pearl millet. Pangenomics identifies the key genes and structural variations associated with pearl millet accessions from the most hot and dry places.
- Dark side of the honeymoon: reconstructing the Asian x European rose breeding history through the lens of genomics. Genomics and other data identifies a shift from a European to a mainly Asian genetic background in cultivated roses during the 19th century, leading to a narrowing of genetic diversity.
Brainfood: Silvopastoral systems, Livestock sustainability, Brachiaria in Brazil, European haymaking, German Black Pied cattle, Mallards, Pollinators, Metabarcoding
- Global meta-analysis reveals overall benefits of silvopastoral systems for biodiversity. They’re not bad on their own, but the best thing for biodiversity would be to integrate silvopastoral systems with protected areas.
- Priority areas for investment in more sustainable and climate-resilient livestock systems. India, Brazil, China, Pakistan and Sudan, apparently.
- Farming cattle in the tropics: Transnational science and industrializing pastures in Brazil. But would investment in Brachiaria-based silvopastoral systems in Brazil be a good thing? I guess it depends.
- Country Perspectives on Hay-Making Landscapes as Part of the European Agricultural Heritage. No Brachiaria in sight.
- Genomic diversity and relationship analyses of endangered German Black Pied cattle (DSN) to 68 other taurine breeds based on whole-genome sequencing. It has a small population, but this ancestor of the Holstein is still pretty diverse. No word on whether it likes Brachiaria.
- The meaning of wild: Genetic and adaptive consequences from large-scale releases of domestic mallards. “Wild is not singular.” Let that sink in while you contemplate your mallard-based silvopastoral system.
- Key tropical crops at risk from pollinator loss due to climate change and land use. I’m sure the right silvopastoral systems would be great for pollinators.
- eDNA metabarcoding of avocado flowers: ‘Hass’ it got potential to survey arthropods in food production systems? Yes it does. So now we can monitor the performance of those silvopastoral systems pretty easily.
Nibbles: Community seedbanks everywhere, USDA genebanks, Public sector plant breeding, Salinity tolerance, Food systems transformation
- Community seedbanks are so big in Zimbabwe that international NGOs are jumping on the bandwagon.
- More from the Cherokee Nation Seed Bank, very much a friend of the blog. International NGOs unavailable for comment.
- Community seedbanks are also in the news in Mexico.
- And in Peru, of course. Oh, here’s a nice video from Peru on Andean roots and tubers, courtesy of CIP, since we’re here.
- Indonesia too, you say? Yeah, why not.
- How to protect genebank collections from climate change, courtesy of USDA. Community seedbanks please take note.
- Who’s going to use all that diversity? Well public sector plant breeders of course.
- Yes, even plant breeders working on Salicornia.
- But how much of the 6 trillion dollars needed for food systems transformation is going to go to genebanks and plant breeding?
Branfood: Salinity tolerance, Comestibles, Underused species, On farm diversity, Minor cereals, Fragrant millet, Wild yams, Fonio, Winged bean, Giant taro, Nutmeg, Mungbean, Finger millet, Amaranth
- Salt-Tolerant Crops: Time to Deliver. Sure, breeding for salt tolerance using crop wild relatives is great, but have you tried just domesticating salt-tolerant wild species?
- Wild and cultivated comestible plant species in the Gulf of Mexico: phylogenetic patterns and convergence of type of use. No word on how many are salt-tolerant.
- Underutilized plants increase biodiversity, improve food and nutrition security, reduce malnutrition, and enhance human health and well-being. Let’s put them back on the plate! No word on how many are salt-tolerant.
- Indigenous crop diversity maintained despite the introduction of major global crops in an African centre of agrobiodiversity. If you want local crop diversity in Highland Ethiopia, look for it on the farms of the poorest. No word on how many are “underutilized”.
- The role of minor cereals in food and nutrition security in Bangladesh: constraints to sustainable production. Low yields, apparently. I think it could do with having aromatic grains. If only there was a way to make that happen…
- De novo creation of popcorn-like fragrant foxtail millet. Yeah, sometimes neither the crop not its wild relatives has the genes for it. Still, if you can edit in aroma, why not salt-tolerance?
- Global Genepool Conservation and Use Strategy for Dioscorea (Yam). I wonder how many of these 27 wild species could usefully be domesticated. Or are salt-tolerant.
- Towards conservation and sustainable use of an indigenous crop: A large partnership network enabled the genetic diversity assessment of 1539 fonio (Digitaria exilis) accessions. This is how you start to undo underutilization. I’m sure someone will edit it next.
- Diversity Assessment of Winged Bean [Psophocarpus tetragonolobus (L.) DC.] Accessions from IITA Genebank. Same as above, but with one hundredth as many accessions. I guess winged bean is even more underutilized than fonio.
- The forgotten giant of the Pacific: a review on giant taro (Alocasia macrorrhizos (L.) G.Don). Sad to say it doesn’t seem to be salt-tolerant. Maybe it’s aromatic, though. Or could be gene-edited to become so. Wouldn’t that be something.
- Retracing the center of origin and evolutionary history of nutmeg Myristica fragrans, an emblematic spice tree species. No need for editing, let’s just conserve the really diverse populations of the North Moluccas.
- Demographic history and distinct selection signatures of two domestication genes in mungbean. Domesticating the mungbean wasn’t all that easy. Hope it’s easier for some random salt-tolerant wild species.
- A plausible screening approach for moisture stress tolerance in finger millet (Eleusine coracana L.) germplasm accessions using membership function value at the seedling stage. Will it work on fonio? Or salt-tolerance?
- Adoption and impact of improved amaranth cultivars in Tanzania using DNA fingerprinting. So can we stop calling it underutilized? And start gene-editing it for aroma?
