Terrestrial plants have two to four times more ATP-binding cassette (ABC) transporter genes than other organisms, including their ancestral microalgae. Recent studies found that plants harboring mutations in these transporters exhibit dramatic phenotypes, many of which are related to developmental processes and functions necessary for life on dry land. These results suggest that ABC transporters multiplied during evolution and assumed novel functions that allowed plants to adapt to terrestrial environmental conditions. Examining the literature on plant ABC transporters from this viewpoint led us to propose that diverse ABC transporters enabled many unique and essential aspects of a terrestrial plant's lifestyle, by transporting various compounds across specific membranes of the plant.
陆地植物的 ATP 结合盒（ABC）转运蛋白基因是其他生物的两倍到四倍，包括它们的原始藻类。最近的研究发现，这些转运蛋白发生突变的植物表现出明显的表型，其中许多与陆地生活所必需的发育过程和功能有关。这些结果表明，ABC 转运蛋白在进化过程中大量增加，并获得了新的功能，使植物能够适应陆地环境条件。从这个角度研究植物 ABC 转运蛋白的文献使我们提出，多样化的 ABC 转运蛋白通过将各种化合物运输到植物的特定膜上，使植物能够适应陆地环境条件，并使植物具有许多独特而重要的生活方式。
