- Phenotypic and physiological responses to salt exposure in Sorghum reveal diversity among domesticated landraces. Salinity tolerance was acquired early but then lost in some geographic regions where it wasn’t needed. See what happens when you invest in a crop?
- Massive haplotypes underlie ecotypic differentiation in sunflowers. It’s the recombination-suppressing inversions, stupid.
- GlobalFungi, a global database of fungal occurrences from high-throughput-sequencing metabarcoding studies. Cool. Do landraces of a crop next.
- The earliest domestic cat on the Silk Road. Coincided with rapid urbanization in the 9th century.
- Native American gene flow into Polynesia predating Easter Island settlement. Yeah, but did Americans go west of their own accord or in Polynesian boats? And did they have sweetpotatoes with them? And cats?
- Genetic markers associated with seed longevity and vitamin E in diverse Aus rice varieties. 5 markers on 4 chromosomes.
- Biogeoinformatics for the management of Farm Animal Genetic Resources (FAnGR). Software for monitoring erosion and detecting locally adapted genotypes. Plus preserve traditional practices.
- Computing on Phenotypic Descriptions for Candidate Gene Discovery and Crop Improvement. Casually talk about a plant in the field –> fancy math –> the plant’s genotype.
- Data synthesis for crop variety evaluation. A review. Focus on ranking. Oh, to mash it up with the above.
- Scenarios for Global Aquaculture and Its Role in Human Nutrition. For aquaculture to contribute to nutrition it needs enabling trade and economic policies. Well I never.
More on making bread Down Under
Do you remember a Nibble from a few weeks back about the bread-making potential of Australian native grasses? If you do, you may have wondered, as we did at the time, what grasses they might be, because “mandadyan nalluk” or “dancing grass” just don’t yield very much additional information on googling.
Well, there’s now a piece in The Conservation that is basically about the same thing, but thankfully links to a scientific name. Or four scientific names, to be exact, for four species in Astrebla, which is a genus that is new to me.
I do love seeing vernacular names in multiple languages being quoted in articles, but I also think they should always be backed-up by a Latin binomial.
And vice versa, of course.
LATER: Wow, The Guardian really likes this stuff. Still no Latin names though.

- Identification and Control of Latent Bacteria in in vitro Cultures of Sweetpotato [Ipomoea batatas (L.) Lam]. 10% of about 2400 in vitro plantlets had a total of about 20 types of bacteria, some of which might be beneficial for all we know, but all of which could be removed.

- Changes in food access by mestizo communities associated with deforestation and agrobiodiversity loss in Ucayali, Peruvian Amazon. Less diversified diets, loss of forest cover and reduced agricultural biodiversity go together, somehow.
- Evaluation of Wild Potato Germplasm for Tuber Starch Content and Nitrogen Utilization Efficiency. Wild species are better on both counts.
- Conservation protocols for Ensete glaucum, a crop wild relative of banana, using plant tissue culture and cryopreservation techniques on seeds and zygotic embryos. 2 accessions thus conserved at NBPGR.

- Arctic-adapted dogs emerged at the Pleistocene–Holocene transition. Sled dogs arose in Siberia, where they interbred with wolves.
- 863 genomes reveal the origin and domestication of chicken. It was Gallus gallus spadiceus from southwestern China, northern Thailand and Myanmar that was domesticated, possibly by rice and millet cultivators, according to Dorian Fuller, who disagrees with the domestication dates but likes the rest of the paper.
- Fodder for Change: Animals, Urbanisation, and Socio-Economic Transformation in Protohistoric Italy. In first-millennium BCE Italy, pigs grew in importance, cattle increased in size, sheep breeds differentiated according to use, and the chickens was adopted and adapted.
- Formalizing land rights can reduce forest loss: Experimental evidence from Benin. Randomized control trial shows land registration is associated with less deforestation.
- Buckwheat (Fagopyrum sp.) genetic resources: What can they contribute towards nutritional security of changing world? Not much until given the full -omics treatment, apparently.
- Pan-Genome of Wild and Cultivated Soybeans. The pan-genome is the new genome. Wait, did I use that before?
- Developing the role of legumes in West Africa under climate change. Lesser know, orphan legumes could step in for cowpea in some places, if only we knew more about them. Like a pan-genome, I guess.
- Evaluation of Nutritional and Antinutritional Properties of African Yam Bean (Sphenostylis stenocarpa (Hochst ex. A. Rich.) Harms.) Seeds. But we do know more about them! Lots of variation available to combat protein malnutrition, if only farmers grew more of the stuff. Oh so now it’s their fault?

Some decline in germinability for about 16% of samples. Includes successful germination protocols for 165 globally threatened seed plant taxa.
