- Status and future of seed conservation of threatened plants in the post-2020 era. 21% of threatened plants are conserved in genebanks across 44 countries in Europe and western Asia. Not bad, but not good enough. I wonder how many of those 21% will be of interest to breeders?
- How the international treaty on plant genetic resources for food and agriculture can support effective germplasm exchange: four Colombian case studies. The Plant Treaty can really help a country’s genebanks and breeders drive agricultural development, given half a chance.

- Impacts of climate change on fonio millet: seed germination ecology and suitability modelling of an indigenous West African cereal. Climate change will screw up the germination of fonio in some places, so genebanks and breeders better get cracking.
- Euterpe edulis seed recalcitrance: difficult, yes, but not impossible to genebank. Tricky seed storage behaviour need not deter genebankers.
- Accelerated aging caused diversity and specificity loss in the bacterial communities of Brassica napus seedlings. Genebanks should be careful with their seed aging experiments, because they might screw up the seed microbiome.

Beat the heat with seeds
I haven’t yet had a chance to read the full FAO–WMO joint report on Extreme heat and agriculture, but some preliminary skimming reveals that agrobiodiversity does seem to be addressed, at least to some extent:
No mention of genebanks, mind you. I guess you can’t have everything, but you’d have thought the following snippets could easily have been used to make the case very explicitly for ex situ conservation of crop diversity.
For domesticated agricultural species, human influence on the genome through selective breeding for enhanced performance in increasingly homogenous production environments has resulted in a loss of natural genetic variability that have accentuated many species vulnerability to temperature extremes.
…
It is only through innovation and the implementation of adaptative measures (e.g. selective breeding, making changes in the physical environment and altering management practices) that the global community can shelter agricultural activities from the larger forces of planetary human induced climate change.
…
Switching to more resilient species to extreme heat may result in reduced genetic diversity, increasing the vulnerability of crops and livestock to large-scale losses due to a narrower genetic base.
Nibbles: Crop mapping, Climate change impacts, Rice cheese, Andean blueberry, Rare apples, Hungarian genebank, Old seed collection
- AI doesn’t recognize tropical agriculture very well.
- So presumably it can’t easily be used in assessing climate change impacts in agricultural heritage systems? FAO has some ideas on how to do it.
- Maybe rice heritage systems can be used to make cheese.
- I bet Andean blueberry (Vaccinium floribundum) goes great with rice cheese.
- But if not, heritage apples will probably do.
- The Hungarian genebank is hoping to inject heritage grains into non-heritage agricultural systems. AI and FAO unavailable for comment.
- Maybe AI can help with the mystery of this old seed collection at the Natural History Museum, London.

Brainfood: Restoration edition
- Addressing critiques refines global estimates of reforestation potential for climate change mitigation. Better mapping shows there is less land available for reforestation than we thought, and there are limited opportunities for providing multiple benefits. Still, that’s an area the size of Mexico, and worth trying to get it right.
