Do you know that cauliflower, broccoli, cabbage and kale are, in fact, the same species? Wonder what driver morphotype diversification between them? Check publication @NatureGenet from scientists at CAAS and @GuusjeBonnema @WUR nature.com/articles/s41588-0…

#Proudmentor. Alexis obtained an undergrad degree in biology last year, working on the first dendrochronology project of the lab. She gave me her graduation stole to represent my good work as a mentor. However, I was a good mentor thanks to her passion and persistence in science
