摘要: ABC转运蛋白超家族结构和功能复杂多样, 包含ABCA-ABCH八个亚家族。ABCB是ABC转运蛋白的一个亚家族, 多数定位于质膜, 少数定位于线粒体膜或叶绿体膜。ABCB与其它生长素转运蛋白(AUX1/LAX、PIN)共同参与调控植物生长素的极性运输, 在植物生长发育的各个阶段发挥作用。此外, ABCB转运蛋白还调控植物的向性运动和重金属抗性等过程。近年来, 随着越来越多植物全基因组测序的完成, ABCB亚家族在禾谷类单子叶植物水稻(Oryza sativa)、玉米(Zea mays)和高粱(Sorghum bicolor)中的生物学功能开始有少量报道, 然而多数ABCB转运蛋白的功能尚未得到阐释。该文对拟南芥(Arabidopsis thaliana)和禾谷类作物ABCB转运蛋白的研究进展进行综述, 以期为全面揭示ABCB亚家族生物学功能提供线索。

Abstract: The superfamily of ABC (ATP-binding cassette) transporters, which contains eight subfamilies from ABCA to ABCH, has diverse structures and complex functions. ABCB transporters, are mostly located in the plasma membrane, while others are located in the mitochondrial membrane or chloroplast membrane. ABCB transporters, together with AUX1/LAX (AUXIN1/LIKE AUXIN) and PIN (PIN-FORMED), coordinate and participate in the polar transport of auxin, and play an important role in regulating plant growth and development. ABCB transporters also function in plant tropism and resistance to heavy metals. In recent years, with the completion of whole-genome sequencing in different plants, research on ABCB genes is no longer confined to the model plant Arabidopsis thaliana, rather, preliminary studies have been carried out to explore the functions of ABCB genes in cereal including rice, maize, and sorghum. However, the functions for most of the plant ABCB transporters remain elusive. Here we reviewed the research progress and future development of ABCB subfamily transporters in Arabidopsis and cereal, in the hope of providing clues for fully revealing biofunctions of the ABCB subfamily.
