ABC转运蛋白与巴西橡胶树产胶代谢

ABC转运蛋白(ATP Binding Cassette transporter)是目前已知最大、功能最广泛的蛋白家族之一。大多数ABC转运蛋白都能利用水解ATP释放的能量直接转运底物。许多研究结果显示，植物ABC转运蛋白在各种代谢产物的跨膜转运中起着重要作用。橡胶的产胶代谢是一种典型的植物类异戊二烯次生代谢，是影响橡胶产量的首要因素。相关实验结果显示，ABC转运蛋白可能参与橡胶树产胶代谢。本文介绍了模式植物拟南芥中的ABC转运蛋白研究进展，并对ABC转运蛋白与橡胶树产胶代谢的关系进行讨论。

ABC Transporters and the Latex Regeneration Metabolism of Hevea brasiliensis

ATP Binding Cassette transporters (ABC transporters) constitute the largest protein family with the most variety of functions. Most ABC transporters can utilize the energy of ATP hydrolysis to transport substances, and many researches reveal that ABC transporters play important roles in translocation of plant metabolites across membranes. Latex regeneration metabolism of Hevea brasiliensis is a typical of plant isoprenoid secondary metabolism and is the primary factor affecting rubber production. Researches reveal that ABC-transporters may be involved in the latex regeneration metabolism of Hevea brasiliensis. Base on the new advances in ABC-transporters in Arabidopsis thaliana, the relation between ABC-transporters and latex regeneration of Hevea brasiliensis was discussed in the review.
