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.
小GTP酶的ROP家族已成为植物信号转导中一种多功能且关键的调节因子。最近的研究表明，ROP信号传导参与了从细胞骨架组织到激素和应激反应等多种过程。作为信号级联早期的开关，ROP还能够协调多个下游途径以放大特定信号。
