🧬🔬 Why are enhancers transcribed and how does that impact gene regulation? I’m really excited to share our new paper in @science.org showing that noncoding RNAs control the timing of gene activation in embryos. With Mike Levine #ScienceResearch @columbiamed.bsky.social A few highlights below... 🧵👇

To add one thing: if you have the data to run both classic dN/dS tests and MK tests, choose the latter. dN/dS tests are blind to positive selection in the important, constrained proteome, while MK test will work regardless of constraint, if DFE well estimated. #evolution #adaptation #popgen

Vienna Doctoral School of Ecology and Evolution
The Vienna Doctoral School of Ecology and Evolution is dedicated to educating students to advance our understanding of the ecology and evolution of extant and ancestral organisms, populations, and communities. In Ecology, the focus is on uncovering the mechanistic and evolutionary drivers of patterns and processes across biological scales, from gene regulation to ecosystem structure and function, including the role of communities in biogeochemical cycles and their adaptive responses to environmental change. In Evolution, we investigate the processes shaping changes in organization and dynamics of organisms, populations, and species at molecular, developmental, morphological, and physiological levels.

That looks great! To avoid errors due to starting with spotty gene annotations (gene loss vs. not annotated), I would suggest re-annotating every genome used with TOGA2 from the Hiller lab: github.com/hillerlab/TO... Many annotations out there are not optimal and TOGA2 has great power and accuracy.
