- Creation of a core set of durum wheat accessions based on agro-morphological traits with maximum diversity and lower redundancy. From 710 to 13 accessions (2%!) using 32 morphological traits, thanks to Power Core.
- Construction of a core collection of Perilla frutescens (L.) Britton Germplasm in the South Korean gene bank using agro-morphological traits. From 1227 to 235 accessions (19%) using 17 morphological traits, thanks to a bunch of different methods.
- Comprehensive Phenotyping of 1,807 Indian Barnyard Millet (Echinochloa frumentacea Link) Accessions from Indian National Genebank: Unlocking Diversity for Core Set Development. From 1,807 to 271 accessions (15%) using 23 quantitative traits, thanks to Core Hunter 3.

Brainfood: Agroecology, Afghan wheat, CWR microbes, Chocolate microbes, Liberica coffee, Wild apples, USDA cotton collection, Parmesan cattle, Sweetpotato genome, Vertical tomatoes
- Embracing new practices in plant breeding for agroecological transition: A diversity-driven research agenda. Plant breeding for agroecology will need access to locally-adapted plant diversity, sure, but also the involvement of a diversity of stakeholders and the use of a diversity of co-design strategies.
- Conservation and Utilization of Wheat Genetic Resources in Afghanistan Expanded with the Homecoming Wheat Landraces Collected Half a Century Ago. The above could also be said of wheat breeding in Afghanistan. Fingers crossed.
- Blueprints for sustainable plant production through the utilization of crop wild relatives and their microbiomes. Oh, wait, breeders (agroecological and otherwise) will also need the diversity of microbiomes associated with crop wild relatives.
- A defined microbial community reproduces attributes of fine flavour chocolate fermentation. Oh, wait, we will also need the diversity of the microbes involved in fermentation, at some point.
- Genomic data define species delimitation in Liberica coffee with implications for crop development and conservation. It might help if we knew how many species made up a crop in the first place. In the case of Liberica coffee, it turns out to be 3. No word on the microbiomes involved.
- Assessment of genetic diversity and population structure of Malus sieversii and Malus niedzwetzkyana from Kazakhstan using high-throughput genotyping. It would also help to know where interesting diversity was concentrated within crop wild relatives. In apples, it’s not necessarily the ancestor.
- The National Plant Germplasm System cotton collection—a review of germplasm resources, phenotypic characterization, and genomic variation. Lots of morphological characterization and agronomic evaluation, not so much molecular data, but increasing. No word on the microbes.
- Establishing a genomic-driven conservation of a cattle genetic resource: the case of the Parmigiano-Reggiano cheese iconic breed. In contrast, these guys have genotyped practically a whole breed. But yeah, no microbes.
- Phased chromosome-level assembly provides insight into the genome architecture of hexaploid sweetpotato. The contributions of different wild relatives to the sweetpotato genome are to be found intertwined along chromosomes rather than restricted to subgenomes. Unclear what that will mean to agroecologial breeders.
- Harnessing Green Revolution genes to optimize tomato production efficiency for vertical farming. Agroecological breeders unavailable for comment.
Tuber or not tuber
A paper in Cell has really caught the imagination of the media in the past few days. You wouldn’t necessarily be able to guess why from its title, though: “Ancient hybridization underlies tuberization and radiation of the potato lineage.” The reason for all the interest, I guess, is that the hybridization in question was between a potato ancestor with no tubers and a plant that was closer to a tomato. Yes, two genes from distant lineages, neither tuber-forming, combined by chance some 9 million years ago to produce the progenitor of all tuber-bearing potatoes, which then diversified as the Andes were uplifted and themselves diversified. Definitely worth the hoopla.
Jeremy also includes the paper in his latest newsletter.
Brainfood: Balanced diets, Diverse diets, Diverse flavonoids, Micronutrients and GHGE, African traditional diets, Tef diversity, Intercropping, Sleeping crops, Cluster bean, Taste
- A framework for adequate nourishment: balancing nutrient density and food processing levels within the context of culturally and regionally appropriate diets. Some processing, but not too much. Some animal-source food, but not too much.
- Diversity of Plant-Based Food Consumption: A Systematic Scoping Review on Measurement Tools and Associated Health Outcomes. And make the non-animal-source food diverse.
- High diversity of dietary flavonoid intake is associated with a lower risk of all-cause mortality and major chronic diseases. Make the flavonoids diverse too, while you’re at it.
- Greenhouse gas emissions in relation to micronutrient intake and implications of energy intake: a comparative analysis of different modeling approaches. It’s unclear whether diets that deliver more (and more diverse?) micronutrient are worse for greenhouse gas emissions.
- Africa’s contribution to global sustainable and healthy diets: a scoping review. African traditional diets are pretty healthy. I’m betting their greenhouse gas emissions are low and all.
- Population genomics uncovers loci for trait improvement in the indigenous African cereal tef (Eragrostis tef). Which is not to say that traditional African crops could not be improved, healthwise.
- Hidden potential of cluster bean: an unexploited legume crop for food and nutritional security. Or other underused traditional crops, for that matter.
- Impacts of biodiversity-positive intercropping systems on food quality, safety and the consumer acceptance: A case study of intercropped wheat. What, the food needs to be intercropped too? Another tick for African diets.
- The sleeping crops of eastern North America: a new synthesis. Traditional eastern North American crops, production systems and diets probably tick a bunch of boxes too. Awake, Cinderellas!
- But does it taste good? A plea to consider the importance of flavor in managing plant genetic resources. None of the above matters, I suspect, if the stuff doesn’t taste good. I’m looking at you, teff and cluster bean.
Brainfood: Complementarity, Temporality, Communality, Fonio trifecta, Atriplex domestication, Egyptian clover in India, Genebank information systems
- A significantly enhanced role for plant genetic resource centres in linking in situ and ex situ conservation to aid user germplasm access. On-farm conservation must result in use of the conserved diversity, and genebanks can help with that. Just another way of saying the two approaches are complementary?
- Looking back to look ahead: the temporal dimension of conservation seed bank collections. Those genebanks may need to do repeated sampling of the same population though.
- Landrace diversity and heritage of the indigenous millet crop fonio (Digitaria exilis): Socio-cultural and climatic drivers of change in the Fouta Djallon region of Guinea. Repeated sampling would defintely have helped.
- Community seedbanks in Europe: their role between ex situ and on-farm conservation. Repeated sampling is kind of what community seedbanks do, no?
- Impacts of climate change on fonio millet: seed germination and suitability modelling of an important indigenous West African crop. Community seedbanks may not be enough though.
- Phylogenetics, evolution and biogeography of four Digitaria food crop lineages across West Africa, India, and Europe. Maybe the wild relatives will help.
- Black Ash – a Forgotten Domestication Trait in Garden Orach (Atriplex hortensis L.). It’s amazing what people domesticated plants for in the past. And might in the future.
- Quality seed production scenario of Egyptian clover (Trifolium alexandrinum) in India: A 24-year retrospective analysis. But in the end, you have to get high quality certified seeds out, and that’s not always easy.
- The potential of seedbank digital information in plant conservation. Will definitely need a pretty good documentation system to keep all the above straight.
