- 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.

Will they come up with something that will work?
Here’s hoping. Follow the proceedings on IISD/ENB. Some background on all this from my work blog.
Nibbles: Banana leaf wilt, EIB, Wheat rust, NUS, Amazon conservation, Snakes & carob, Global farmers, Spud genes
- Bananas resistant to bacterial wilt found at last.
- The Ethiopian genebank gets the very cool Atlas Obscura treatment.
- It needs a helping hand, though. Technology to the rescue in wheat rust management.
- Diversify your diet, why don’t you.
- Giving standing trees value in the Amazon. Great drone shots too.
- Carob trees have value in Cyprus.
- Also nice pix in this Guardian photo essay on how farmers fight climate change.
- Genotyping the CIP collection. That includes the humble potato, of course.
Brainfood: Forests & diets, Homegardens & diets, Landsparing, NZ megafauna, Broomcorn millet origins, Aflatoxin in peanut, Sorghum nutrients, Sorghum & sugarcane diversity in Ethiopia, Hawaiian seedsaving, English sustainability, Wheat evaluation, Lentil review, Danish apples
- Impacts of forests on children’s diet in rural areas across 27 developing countries. Exposure to forests is good for dietary diversity.
- The Role of Homegardens for Food and Nutrition Security in Uganda. Homegardens too.
- The challenge of feeding the world while conserving half the planet. Sparing biodiversity-rich areas means food production will take a hit.
- Human Perceptions of Megafaunal Extinction Events Revealed by Linguistic Analysis of Indigenous Oral Traditions. The Maori were aware of what was happening to the moa.
- Perpetuating Agricultural Heritage: Saving Seeds and Stories on Hawai‘i Island. Diverse messaging needed to reflect diverse motivations. Maybe that would have helped the moa.
- Genetic evidence for a western Chinese origin of broomcorn millet (Panicum miliaceum). Not northern China, nor eastern Europe.
- New tools to screen wild peanut species for aflatoxin accumulation and genetic fingerprinting. Let the screening begin.
- Identification of new donors for spot blotch resistance in cultivated wheat germplasm. 7 out of 1483 from the Indian collection. Hard row to hoe
- Nutritional variation in sorghum [Sorghum bicolor (L.) Moench] accessions from southern Africa revealed by protein and mineral composition. Among 23 accessions, two are good for both Fe and Zn, a different one for protein, Ca and P, and a different one still for Ca and K.
- Farmers’ synergistic selection criteria and practices for livelihood security through the sustainable uses of onfarm Sorghum landrace diversity, Ethiopia. Diverse selection criteria reflect diverse uses.
- Sugarcane Landraces of Ethiopia: Germplasm Collection and Analysis of Regional Diversity and Distribution. Variation follows altitude. Compare and contrast with above.
- To what extent has sustainable intensification in England been achieved? Not much, and only quite recently.
- Lentils: Genetic Resources: Collection, Conservation, Characterization and Maintenance. More work on wild relatives needed.
- Population structure, relatedness and ploidy levels in an apple gene bank revealed through genotyping-by-sequencing. 78% of 349 apple accessions in the Danish genebank are unique.
Nibbles: CRS, Finger millet breeding, Amazonian cacao, Alelo & Genesys, Ag origins double, USDA genebank
- Q&A with Susan Bragdon of Seeds for All on the importance of agrobiodiversity and small farmers.
- Going wild for finger millet in Kenya.
- There’s maybe a previously unknown variety of cacao.
- Brazilian germplasm collection data online.
- A very Fertile Crescentic view of agricultural origins.
- Antidote to above.
- Ft Collins USDA genebank in the (local) news.
