New study shines light on how plant cells perceive and respond to mechanical forces

New study shines light on how plant cells perceive and respond to mechanical forces Minuscule tunnels through the cell membrane help cells to perceive and respond to mechanical forces, such as pressure or touch. A new study in the journal Science is among the first to directly investigate what one type of these mechanosensitive ion channels is doing in the tip-growing cells in moss and pollen tubes of flowering plants, and how. Biologists led by Elizabeth Haswell at Washington University in St. Louis discovered that so-called PIEZO channels are not found along the plasma membrane in plant cells as they are in animal cells.
