Peeling back the layers: Functional differentiation between Kalanchoë fedtschenkoi epidermis and mesophyll proteomes

What proteins exist in the epidermis layer and how they compare to the proteins in the surrounding mesophyll cells represents a major knowledge gap for how CAM plants thrive in environments with high temperatures and long periods of severe water deficit. Therefore, we performed large-scale proteomics to characterize proteins in epidermis and mesophyll cells from leaves of the constitutive CAM plant Kalanchoë fedtschenkoi.
