Ben Engel @cellarchlab.com · Sep 25 Our data enabled us to quantify native thylakoid architecture in the grana. Getting precise numbers is important for modeling photosynthetic regulation. Here’s a comparison to similar measurements made by classical TEM. We’d like to apply #CryoET to the dark-to-light💡 transition in the future. 4/🧵

Contrary to previous models, our native views showed that grana are not perfect cylinders, but have wavy undulating edges 🌊🏄♀️. Here we slice through a few grana🥞 from the top– Do you see all the little protein densities in the membranes?🔍 Those are photosynthetic complexes. How to analyze them? 5/🧵
