Review: Plasma membrane-to-organelle communication in plant stress signaling (Curr. Opin. Plant Biol.)
The plasma membrane (PM) is a critical interface between the cell and its environment and serves crucial sensing and transducing roles. This timely review by Medina-Puche and Lozano-Durán updates exciting new developments in understanding communication between the PM and intracellular organelles, focusing on abiotic and biotic stresses. The review sorts these interactions into three types: physical contact and molecular exchange (for example direct contacts between the endoplasmic reticulum and plasma membrane); protein trafficking (e.g., internalization of membrane-bound receptors); and small molecules mediating communication (e.g., Ca2+, H+, ROS). Each of these types is illustrated with several examples, to highlight the commonalities and distinctions. This is an excellent, thought-provoking review that highlights the many ways that information flows from out to in. (Summary by Mary Williams @PlantTeaching) Curr. Opin.
