摘要：

Cell polarity is fundamentally important to plant growth and development, yet the mechanism governing its development is understood poorly. Several studies have revealed a role for Rop GTPases in pollen polar tip growth. Rop is also localized to the future site of root hair development and the tip of root hairs, and expression of constitutively active Rop mutants impacts on the morphogenesis of tip-growing root hairs as well as on non-tip-growing cells. These findings highlight the importance of Rop as a common switch in cell polarity control in plants.
