New paper out!
Thrilled to share our latest work on cytonuclear interactions in Populus hybrid zones, now published in Proceedings B.
We show how mismatches between nuclear and chloroplast genomes influence key physiological traits in tree species @jillahamilton.bsky.social

The role of cytonuclear interactions to plant adaptation across a Populus hybrid zone | Proceedings of the Royal Society B: Biological Sciences
Co-adaptation of cytoplasmic and nuclear genomes is critical to physiological function
for many species. Despite this understanding, hybridization can disrupt co-adaptation,
leading to a mismatch betw...
