在植物中，ABC 转运蛋白 PDR（多效抗药性）亚家族由大约 15 个基因组成，其中很少有基因被分析过。我们已经鉴定出 NtPDR3，一种烟草 PDR 基因，属于之前没有功能数据的簇。 NtPDR3被发现在用茉莉酸甲酯、水杨酸、1-萘乙酸或西柏烯（一种大环二萜）处理的悬浮细胞中被诱导。与 NtPDR3 转录启动子区域中假定缺铁元件的鉴定一致，我们发现培养基中缺铁诱导 NtPDR3 表达，从而表明 PDR 转运蛋白家族的新功能。 (c) 2005 年欧洲生化学会联合会。由 Elsevier B.V. 出版。保留所有权利。
In plants, the ABC transporter PDR (pleiotropic drug resistance) subfamily is composed of approximately 15 genes, few of which have been analyzed. We have identified NtPDR3, a Nicotiana tabacum PDR gene belonging to a cluster for which no functional data was previously available. NtPDR3 was found to be induced in suspension cells treated with methyl jasmonate, salicylic acid, 1-naphthalene acetic acid, or cembrene, a macrocyclic diterpene. In agreement with the identification of a putative iron deficiency element in the NtPDR3 transcription promoter region, we found that iron deficiency in the culture medium induced NtPDR3 expression, thus suggesting a new function of the PDR transporter family.
