Hormone transporters are crucial for plant hormone action, which is underlined by severe developmental and physiological impacts caused by their loss-of-function mutations. Here, we summarize recent knowledge on the individual roles of plant hormone transporters in local and long-distance transport. Our inventory reveals that many hormones are transported by members of distinct transporter classes, with an apparent dominance of the ATP-binding cassette (ABC) family and of the Nitrate transport1/Peptide transporter family (NPF). The current need to explore further hormone transporter regulation, their functional interaction, transport directionalities, and substrate specificities is briefly reviewed.
激素转运蛋白对于植物激素作用至关重要，其功能丧失突变会导致严重的发育和生理影响。在这里，我们总结了植物激素转运蛋白在局部和长距离运输中的作用的最新知识。我们的清单显示，许多激素由不同转运蛋白家族的成员运输，其中 ABC 家族和硝酸盐转运蛋白 1/肽转运蛋白家族（NPF）明显占主导地位。简要回顾了目前需要进一步探索激素转运蛋白的调节、它们的功能相互作用、运输方向和底物特异性。
