- New technologies to improve the ex situ conservation of plant genetic resources. Genebanks need to catch up with the latest science even just to maintain their seeds.
- Advanced Strategic Research to Promote the Use of Rice Genetic Resources. High-throughput phenotyping and genome sequencing are the latest science that will make the most of those seeds.
- Phased diploid genome assemblies and pan-genomes provide insights into the genetic history of apple domestication. Analysis of genomes of two main wild progenitors plus the crop uncovers genes so far untapped for improvement.
- The elephant grass (Cenchrus purpureus) genome provides insights into anthocyanidin accumulation and fast growth. It’s related to pearl millet, apparently. Which may or may not be a good thing. No word on any genes so far untapped for improvement.
- Triticum population sequencing provides insights into wheat adaptation. Wide adaptation is largely due to introgression from the wild. No word on any genes so far untapped for improvement.

- Brain Size Does Not Rescue Domestication Syndrome. Not even for humans, I suspect. Kidding apart, this is fascinating. It suggests that, for animals at least, the domestication syndrome is not actually a thing. Or at least has not been properly tested. If there’s interest, I’ll do a full post. Let me know in the comments below.
- Ancient genomes reveal tropical bovid species in the Tibetan Plateau contributed to the prevalence of hunting game until the late Neolithic. The now tropical gaur ranged much further north during the warmer Neolithic, which facilitated the exploration of the Tibetan Plateau.
- Optimization of in vitro germination and cryopreservation conditions for preserving date palm pollen in the USDA National Plant Germplasm System. Always good to have another way of storing germplasm.
- Beyond the material: knowledge aspects in seed commoning. Comparing global with local seed commons reveals importance of managing knowledge, both scientific and traditional.
- Genetics to the rescue: managing forests sustainably in a changing world. To manage forests sustainably, you have to conserve and use their genetic diversity. Interesting that they needed a conference to work that out.
- Genetic mixing for population management: from genetic rescue to provenancing. And using that genetic diversity could mean mixing it up.
- The importance of genomic variation for biodiversity, ecosystems and people. Maintaining ecosystem services means maintaining genetic diversity. Sounds like these authors went to the same conference.

More population differentiation for tropical, mixed‐mating, non‐woody species pollinated by small insects, and lower for temperate, outcrossing trees pollinated by wind. Could perhaps be mashed up with this fragmentation database.
