- Genome-wide comparative diversity uncovers population structure, global distribution, and targets of selection in hexaploid oat. A worldwide survey reveals how oat diversity is structured, spread, and shaped by breeding, helping pinpoint untapped genetic resources for future improvement.
- Genomic diversity and the domestication history of cotton (Gossypium hirsutum). Its genome traces cotton’s journey from its wild origins in Mesoamerica while documenting the genetic narrowing that accompanied domestication.
- Genetic architecture of sugarcane traits in a polyploid genomics framework. New genomic tools finally begin to untangle the diversity of one of agriculture’s most genetically complex crops, exposing the basis of traits breeders have long selected largely in the dark.
- Projected warming will exceed the long-term thermal limits of rice cultivation. Rice has historically thrived within remarkably stable climatic boundaries. Those boundaries are now on course to be crossed across major growing regions, with profound implications for global food security. Diversity to the rescue?
- An inter-specific Amaranthus pangenome captures genetic variation potentially underlying key leafy vegetable traits in this underutilised crop. A rich reservoir of previously hidden diversity emerges from across multiple cultivated amaranths, offering breeders new options for improving a neglected but nutritious vegetable.
- Impact of gardening and nutrition support provided to women in refugee camps in Cox’s Bazar, Bangladesh. Even in one of the world’s most challenging humanitarian settings, greater interspecific crop diversity translated into better diets, improved food security, and enhanced wellbeing.
- Designing perennial crop-based agroforestry systems: specificities, challenges, and opportunities. Diversification does not stop at the field edge: how perennial crops can be combined with trees to deliver productive, resilient, and biodiversity-friendly farming systems.
- Towards Nature Positive supply chains: From biodiversity commitments to organisational action. What would it take to move biodiversity from corporate promises to business practice? Maybe the above examples can help inform a roadmap for turning aspiration into measurable action.
Nibbles: Johnny Appleseed, ICRAF genebanks, China lychee genebank, Ethiopian Biodiversity Institute, Saudi tree genebanks, European genebank data, Pricing nature
- Johnny Appleseed basically set up fruit tree genebanks 200 years ago.
- Modern fruit tree genebanks could probably learn something from Mr Appleseed.
- Is there a Mr Lycheeseed, I wonder?
- There are probably some fruit tree collections at the Ethiopian Biodiversity Institute.
- Saudi Arabia is betting on tree genebanks. Maybe even fruit tree genebanks.
- All genebanks need to share their data, according to the guy in charge of helping European genebanks share their data.
- Can you put a value on genebanks? Should you?
Stairway to maize diversity
There’s a nice article in Rising Kashmir highlighting that region’s cold-tolerant maize landraces as a unique source of genetic diversity. What I liked about it is that it doesn’t condescend to its audience. It’s unapologetically technical and niche, while successfully (I think) striving to be understood by all. That’s rare. The author, Dr Salika Ramazan, argues that long adaptation to Himalayan environments has produced valuable traits for climate resilience and future maize breeding, and advocates for urgent conservation before this irreplaceable diversity is lost.
A quick search on Genesys revealed 302 maize accessions from above 1500 masl in the Himalayas (yellow on the map below), and 62 above 2500 masl (red). Of course, there are many more maize accessions from high altitudes in Central and South America, but their photoperiod adaptation (among other things) is likely to be quite different.

Nibbles: Fit for Biodiversity, Food value chains, FAO, SeedTracker, Morocco genetic erosion, Pastoralists, Cannabis seedbanks
- A conference on biodiversity in agri-food systems. Including agrobiodiversity?
- A photo essay about food value chains in India. Including agrobiodiversity?
- A few examples of FAO’s work on how agriculture sustains biodiversity. Including agrobiodiversity.
- An app to track seeds. And therefore agrobiodiversity.
- A warning that 75% of the agrobiodiversity of Morocco’s wheat and barley has been lost in the past 50 years. Ah, so that 75% number is true of something after all. Maybe they could use SeedTracker.
- A reminder that pastoralists guard biodiversity. Including agrobiodiversity.
- A Genesys for weed. Well, I guess it’s agrobiodiversity.
Nibbles: Svalbard prize, Rice breeding, Coffee geography, Biodiversity loss monitoring, Spatial data
- The Svalbard Global Seed Vault gets the Princesa de Asturias Prize for international cooperation. Time to celebrate.
- Celebrating Pamela Ronald and scuba rice.
- Celebrating Ohsoon Yun and the geography of coffee.
- I’ll certainly celebrate if the approach of the NATURE-FIRST project can be applied to loss of agricultural biodiversity one day.
- The World Bank is in a celebratory mood with regards to geospatial and Earth observation data. I’ll join them when they fund a NATURE-FIRST for crop diversity.
