- Whole-genome landscape of Medicago truncatula symbiotic genes. There’s always something else.
- Genebank genomics highlights the diversity of a global barley collection. IPK’s, that is, and that’s 22,000 strong. Let the GWAS begin. Including for whisky-related traits, of course.
- A polyploid admixed origin of beer yeasts derived from European and Asian wine populations. And beer-related.
- Genetic diversity and population structure of a mini-core subset from the world cowpea (Vigna unguiculata (L.) Walp.) germplasm collection. There are three broadly geographic clusters, and the mini-core is representative of overall diversity, in Africa at least.
- Identification of candidate domestication‐related genes with a systematic survey of loss‐of‐function mutations. Fancy methods lead to doubling of possible domestication genes in soybean to 110.
- Social Valuation of Genebank Activities: Assessing Public Demand for Genetic Resource Conservation in the Czech Republic. Willingness to pay is $9 per sample. But this is unpacked in a guest post by Nik.
- Gene bank scheduling of seed regeneration: Interim report on a long term storage study. Maybe someone can tell me what’s new here?

- Dietary Diversity: Implications for Obesity Prevention in Adult Populations: A Science Advisory From the American Heart Association. As currently defined, dietary diversity does not necessarily mean healthy eating.
- Modern Wheat Varieties as a Driver of the Degradation of Spanish Rainfed Mediterranean Agroecosystems throughout the 20th Century. Under traditional organic management, older varieties have similar yields to modern varieties, plus more biomass both above and below ground, making for better soils.
- Peculiarly pleasant weather for US maize. Adaptation to warmer climates accounts for 28% of yield increases since 1981. It won’t last, see below.
- Increase in crop losses to insect pests in a warming climate. Losses to insects will increase by 10 to 25% per degree Celsius of warming for wheat, rice, and maize.
- Metabolite variation in the lettuce gene pool: towards healthier crop varieties and food. Tasty lettuce is possible.
- Genome sequences of two diploid wild relatives of cultivated sweetpotato reveal targets for genetic improvement. Carotenoid biosynthesis alleles identified.
- Climate change stimulated agricultural innovation and exchange across Asia. Climate models suggest that about 3,500 years ago Central Asia and Tibet cooled, and 2,000 years ago China followed suit, in both cases leading to shifts in crops.
- Intensification for redesigned and sustainable agricultural systems. Depends on building social capital first.

- Let them grow coca.
- Well, it is sort of agroforestry, right?

- Securing Diversity for Food Security: The Case of Conservation and Use of Rice Genetic Resources. Great achievements, but “… 95% of the rice genepool remains untapped and unexploited in rice improvement.”
- Characterization and Identification of Indigenous Olive Germplasm from Cyprus Using Morphological and Simple Sequence Repeat Markers. 125 trees, 32 accessions, 16 genotypes, 3 groups.
- Quantification of Selected Anti-nutrients and Bioactive Compounds in African Bambara Groundnut (Vigna subterranea (L.) Verdc.). Nothing to worry about, but if you insist on worrying, try the cream-coloured ones.
- DNA Fingerprinting and Genetic Diversity Analysis with Simple Sequence Repeat Markers of 217 Potato Cultivars (Solanum tuberosum L.) in China. Cultivars released since 1950 have a narrow genetic base.
- Pastoralism may have delayed the end of the green Sahara. What have pastoralists ever done for us?
- Epigenetic Diversity and Application to Breeding. Some epigenetic differences can be inherited independently of genetic differences. But how to use it?
- Complex rice systems to improve rice yield and yield stability in the face of variable weather conditions. The more azolla, fish and ducks the better.
- Can plants evolve to meet a changing climate? Yes, and we can detect it: the potential of field experimental evolution studies.
- Wheat’s wild relatives vary in their response to nitrogen and ozone. In situ populations may be at risk.
- Little evidence that farmers should consider abundance or diversity of arbuscular mycorrhizal fungi when managing crops. One less thing to worry about? Ok, one fewer thing to worry about.
- Exclusivity offers a sound yet practical species criterion for bacteria despite abundant gene flow. Taxa do exist if you take the whole genome into account.
Brainfood: Yak diversity, Wheat pre-breeding, Gene conservation, Genome conservation, Wild lentils, Biodiversity definition, Conservation reviews, Bananas treble, Cotton diversity, Pollinator health, Aurochs DNA, USDA cucumbers, Physalis editing, Tomato re-domestication
- Identification and diversity of Y‐chromosome haplotypes in Qinghai yak populations. 2 paternal lineages but weak genetic structure among the 9 populations and 3 breeds.
- Development and characterization of Triticum turgidum–Aegilops umbellulata amphidiploids. A bridge to bread wheat.
- Variation in total root length and root diameter of wild and cultivated lentil grown under drought and re-watered conditions. Some wild species have longer total root length under drought stress than crops. No word on whether bridges needed.
- The Peril of Gene-Targeted Conservation. Only warranted when said targeted genes are important for viability and have large phenotypic effects. Suspect crop breeders (see above) may beg to differ.
- Conservation of biodiversity in the genomics era. Need to target the whole genome, I guess.
- “What Matters Is Species Richness” — High School Students’ Understanding of the Components of Biodiversity. Must try harder.
- What Conservation Does. The right things, more or less, and not at all badly, so stop complaining.
- Absence of evidence for the conservation outcomes of systematic conservation planning around the globe: a systematic map. It’s not evidence of absence of conservation outcomes, but still. Maybe should get together with the above?
- East African diploid and triploid bananas: a genetic complex transported from South-East Asia. All introduced by Austronesian people, probably via Madagascar, but no longer to be found in Asia (much).
- Molecular and Cytogenetic Study of East African Highland Banana. Focuses on one of the 4 groups discussed in the above (Mutika). All derived from maybe a single hybrid clone.
- Sources of resistance to Xanthomonas campestris pv. musacearum, the causal agent of banana Xanthomonas wilt. Why bother with the above, you ask?
- Genetic diversity of day-neutral converted landrace Gossypium hirsutum L. accessions. Eastern and western hemisphere groups, with US varieties closer to the eastern.
- Crop Domestication Alters Floral Reward Chemistry With Potential Consequences for Pollinator Health. In highbush blueberry, domestication has decreased the chemical diversity of nectar and pollen, possibly increasing infection by bee gut pathogens.
- Ancient DNA analysis of Scandinavian medieval drinking horns and the horn of the last aurochs bull. Aurochs interbred with domestic cattle way back. In other news, you can extract aurochs DNA from medieval Scandinavian drinking horns.
- The USDA cucumber (Cucumis sativus L.) collection: genetic diversity, population structure, genome-wide association studies, and core collection development. Three groups, more or less: India, E. Asia, and everything else. A third of 1200 accessions recovers 96% of variation.
- Rapid improvement of domestication traits in an orphan crop by genome editing. Tomato orthologues in groundcherry mutated for more fruits and better plant architecture.
- Domestication of wild tomato is accelerated by genome editing. Or you can do it with the actual tomato genes. As suggested a couple of years ago.
