When AlphaFold was released, there was a lot of talk that it marked the end of structural biology. That is far from the case. We will, I’m sure, hear similar comments with the emergence of AI co-scientist agents. AI is just a tool but It will never replace a scientist’s intuition & experience.

Plants use immunogenic peptides to coordinate immunity. Pathogens can mimic them to hijack defense. 🌱 We compare phytocytokines with animal cytokines and ask how these signals are made, released, mimicked, and controlled in space and time.
