We’re excited to share our new work on how plants restore cytonuclear balance after whole-genome duplication. Using Arabidopsis auto- and allopolyploids, we uncover distinct, organelle-specific strategies in chloroplasts and mitochondria across generations. doi.org/10.1111/tpj....

Punctuated equilibrium, a concept introduced by paleontologists in 1972, reimagines evolution’s tempo as a stochastic burst rather than a steady beat.

I wrote about gene-gene interactions (epistasis) and the implications for heritability, trait definitions, natural selection, and therapeutic interventions. Biology is clearly full of causal interactions, so why don't we see them in the data? A 🧵:
