The Plant Cell in a Nutshell: The dance of the vesicles
Yan and co-workers follow the localization of various membrane proteins upon blocking clathrin- and adaptor protein-mediated membrane trafficking, and reveal that blocking endocytosis reduces exocytosis (and vice-versa). https://doi.org/10.1093/plcell/koab180

Get it Sorted: A Classic Endocytic Sorting Mechanism in Mammals is Conserved in Plants
The plasma membrane (PM) is an exquisitely dynamic structure. It has to be, since it serves as the interface between the cell and the ever-changing environment. PM-associated signaling proteins shuttle quickly between the PM and the cell’s interior to help the organism respond to whatever comes its…
