Auxin controls many aspects of the growth and development, including apical dominance and vascular development. The maintenance of apical dominance needs basipetal transport of auxin in the atem. Auxin efflux carrier protein is an important factor of basipetal transport of auxin in the stem. In this report we analyzed the relationship between the expression of pea auxin efflux carrier, PsPIN1,and auxin in detail. The expression amount of PsPIN1 was increased by application of IAA to the stump of decapitated stem, but decreased by lanolin alone. PsPIN1 was expressed in the manner coincident with the rate of the basipetal transport of IAA that applied to the stump of stem, in which PsPIN1 had not been expressed. These results indicated that PsPIN1 is induced by auxin, and suggested that auxin efflux carrier plays a part of role in vascular development.
