- Global wind patterns shape genetic differentiation, asymmetric gene flow, and genetic diversity in trees. The wind is blowing the answer, my friend.
- Social network analysis of the genealogy of strawberry: retracing the wild roots of heirloom and modern cultivars. Some 1500 contributors to the current, quite diverse cultivated genepool, from numerous species.
- Is Domestication Speciation? The Implications of a Messy Domestication model in the Holocene. They could have used the above as an additional example. But the answer to the question in the title seems to be that it doesn’t matter much, and I’m there for that.
- Phenotypic divergence between the cultivated apple (Malus domestica) and its primary wild progenitor (Malus sieversii). Oh, look, you don’t need fancy genotyping to tell that wild and cultivated apples are different species. No word on the role of global wind patterns though.
- Genetic diversity and population structure of advanced clones selected over forty years by a potato breeding program in the USA. Going from 214 to 43 clones doesn’t seem a game worth the candle, but someone will no doubt set me right.
- The Adoption of Landraces of Durum Wheat in Sicilian Organic Cereal Farming Analysed Using a System Dynamics Approach. Follow the money.
- Rediscovering ‘Mexican June’: a nearly extinct landrace maize (Zea mays L.) variety. Yes, there is money in organic systems.
- Modeling impacts of faster productivity growth to inform the CGIAR initiative on Crops to End Hunger. Following the money.
- Nutritional diversity and community perceptions of health and importance of foods in Kiribati: a case study. Local foods are seen to be healthier than imported, but nobody cares. Maybe because people are following the money?
- Governing crop genetics in post-Soviet countries: lessons from the biodiversity hotspot Armenia. Any progress that has been made is due to committed individuals. There’s a lesson there for us all.
- Archaeological science meets Māori knowledge to model pre-Columbian sweet potato (Ipomoea batatas) dispersal to Polynesia’s southernmost habitable margins. Archaeology confirms traditional oral history. A lesson there too.
- Factors influencing household pulse consumption in India: A multilevel model analysis. Households that grown more pulses, eat more pulses. There endeth the lesson.

Managing seed on the web
The ambition of the CoEx ((Gouvernance adaptative des stratégies de gestion de la diversité cultivée)) project is to improve our understanding of the gap between (1) seed policies and laws and (2) farmers’ seed management practices. Such a gap is detrimental to the access and mobilization of a wide variety of seeds by farmers.
Intrigued? Speak French? There’s a webinar on the project today.

- The Corylus mandshurica genome provides insights into the evolution of Betulaceae genomes and hazelnut breeding. Yeah, but can it make Nutella better?
- Widely assumed phenotypic associations in Cannabis sativa lack a shared genetic basis. More work needed. Much more work.
- Dissecting industrial fermentations of fine flavour cocoa through metagenomic analysis. There’s a core of microorganisms in common even in very distant farms. Though I suspect the fun will be in the others.
- Widespread lateral gene transfer among grasses. Especially in rhizomatous species. That should relieve the anxiety about genetic modification, right? Right.
- An agroecological vision of perennial agriculture. Wait, what about those rhizomatous perennial grasses, though?
- Comparison of benchtop and handheld near‐infrared spectroscopy devices to determine forage nutritive value. The handheld devices are just fine. How long before Alice asks Chris for some for the ILRI genebank? To test on rhizomatous grasses, of course.
- Historical Indigenous Land-Use Explains Plant Functional Trait Diversity. Forest gardens in the Pacific NW still have more diversity 150 years after their indigenous managers were forced off them.
- The minimum land area requiring conservation attention to safeguard biodiversity. 44% of terrestrial area, home to 1.8 billion people. Presumably including a lot of indigenous managers.
- People have shaped most of terrestrial nature for at least 12,000 years. 75% of terrestrial area, in fact.
- Protection of honeybees and other pollinators: one global study. Focus on habitat loss and pesticides. And more monitoring.
- A sexual division of labour at the start of agriculture? A multi-proxy comparison through grave good stone tool technological and use-wear analysis. Guess which gender was buried with tools associated with interpersonal violence.
- Origins of house mice in ecological niches created by settled hunter-gatherers in the Levant 15,000 y ago. Well, hence the name, right?
- Commentary: Underestimating the Challenges of Avoiding a Ghastly Future. Don’t warn. Resist.

- Whole-genome resequencing of 445 Lactuca accessions reveals the domestication history of cultivated lettuce. Originally domesticated in the Caucasus, for oil, and then a long, slow wander westward. But so much more to it…
- Variability and trait‐specific accessions for grain yield and nutritional traits in germplasm of little millet (Panicum sumatrense Roth. Ex. Roem. & Schult.). From 200 accessions to 5 both high yielding and rich in Ca.
- Genomic and phenotypic characterization of finger millet indicates a complex diversification history. Wait, East Africa is the least genetically diverse area?
- Portrait of a genus: the genetic diversity of Zea. There has been convergent adaptation in high altitude teosinte and high latitude (temperate) maize.
- Genetic diversity of African wild rice (Oryza longistaminata Chev. et Roehr) at the edge of its distribution. The Ethiopian material is special.
- Candidate genes and signatures of directional selection on fruit quality traits during apple domestication. Fruit colour and taste genes lose diversity during domestication.
- The Evolutionary History of Wild, Domesticated, and Feral Brassica oleracea (Brassicaceae). B. cretica is the closest wild relative.
- Brassica rapa domestication: untangling wild and feral forms and convergence of crop morphotypes. The truly wild stuff comes from the Caucasus, Siberia and … Italy. But it all goes back to turnips in the Hindu Kush.
- ‘Neodomesticates’ of the Himalayan allium spices (Allium species) in Uttarakhand, India and studies on eco-geography and morphology. Gotta know your onions.
- Multiple independent recombinations led to hermaphroditism in grapevine. The switch from dioecious to hermaphroditic flowers happened two times in the last 6000 years, but before domestication.
- Revitalization of the Greek Vitis database: a multimedia web-backed genetic database for germplasm management of Vitis resources in Greece. Welcome back!
- Participatory Plant Breeding and the Evolution of Landraces: A Case Study in the Organic Farms of the Collserola Natural Park. From 80 plants of the Mando tomato landrace to over 2000.
- Evidence for early dispersal of domestic sheep into Central Asia. Sheep were being kept in the Ferghana Valley 3000 years earlier than thought.
- A metric for spatially explicit contributions to science-based species targets. Sustainable crop production and forestry in Indonesia, Colombia, Mexico, Madagascar and Brazil would make a hell of a difference.
- Conserving intraspecific variation for nature’s contributions to people. Oh good, I’m glad somebody thought of this.
