ABC transporters are essential for plant development, playing roles in processes such as gametogenesis, seed development, seed germination, organ formation, and secondary growth. ABC transporters are directly energized by ATP and can transport complex organic materials against concentration gradients; thus, they are uniquely suited to provide the complex building blocks required for the development of specialized plant cells. We review recent progress in our understanding of the contribution ABC transporters make to the growth and development of plants, including their roles in protective layer formation and in transporting phytohormones.
ABC 转运蛋白对于植物的发育是必不可少的，它们在配子体发生、种子发育、种子萌发、器官形成和次生生长等过程中发挥作用。ABC 转运蛋白由 ATP 直接供能，可以逆浓度梯度转运复杂的有机物质；因此，它们非常适合为特化植物细胞的发育提供所需的复杂构建块。我们回顾了近年来我们对 ABC 转运蛋白在植物生长和发育中的作用的理解进展，包括它们在保护层形成和运输植物激素方面的作用。
