Abstract

The ROP family of small GTPases has emerged as a versatile and pivotal regulator in plant signal transduction. Recent studies have implicated ROP signaling in diverse processes ranging from cytoskeletal organization to hormone and stress responses. Acting as a switch early in signaling cascades, ROPs are also capable of orchestrating several downstream pathways to amplify a specific signal.
