中文摘要：

生长素极性运输影响植物的生长和发育．在植物器官形态建成、发育等过程中发挥重要的调控作用．生长紊极性运输是一个依赖于生长素运输载体来完成的复杂过程．近年来生长素极性运输载体AUX／LAX蛋白、HN蛋白家族和MDR／PGP蛋白家族在生长素极性运输中作用的研究日益深入，并且在植物激素联系和转运方面取得了重大发现——PILC蛋白．

英文摘要：

The physiological and development process of plants are affected by the polar transport of auxin, which plays an important role in the regulation of plant organ formation and development. And the polar transport of auxin, a complex process, is depended on auxin transport carriers. In recent years, more and more researches are focused on the effect of different carriers on the polar transport of auxin, including AUX/LAX proteins, PIN （PIN-PORMED） protein families and MDR/PGP protein families. In addition, a new carrier-PILC protein was discovered, which influence the plant hormones contact and transporter.
