Guannan Wang and collaborators in the Schiefelbein and Dassanayake labs generated cell-type-resolved expression atlases of roots from several Brassicaceae species, including stress-tolerant extremophytes, under control and stress conditions. Comparing homologous cell types across species revealed which expression programs are conserved and which have diversified, and showed that stress responses have evolved in a cell-type-specific manner.
