this project began in the winter while plants and (root-knot) nematodes were bulking and experiments had to slow - thanks again to niels for supporting me in exploring new ideas and venturing out of my comfort zone!

Network properties constrain natural selection on gene expression in Caenorhabditis elegans
Gene regulatory networks (GRNs) integrate genetic and environmental signals to coordinate complex phenotypes and evolve through a balance of selection and drift. Using publicly available datasets from...

we believe our findings are largely consistent with macroevolutionary theories of transcriptome evolution - this suggests that gene regulatory networks might evolve in similar ways across time scales

key takeaways

⚖️ selection is mostly weak - drift dominates!

🕸️ core genes face stronger stabilizing selection (but trans-regulatory variation can relax this)

🧠 tissue-specific genes are under stronger selection - with neuronal and reproductive tissues evolving the fastest

what we did:

🧬 we used genotypic selection analyses to link variation in transcript levels to fecundity to test how natural selection shapes transcriptomes within a single generation

🕸️ we then integrated our models with network models to explore what constrains/drives transcriptome evolution
