Abstract

The genes enconding proteins containing plasma membrane proteolipid 3 (PMP3) domain are responsive to abiotic stresses, but their functions in maize drought tolerance remain largely unknown. In this study, the transgenic maize lines overexpressing maize ZmPMP3g gene were featured by enhanced drought tolerance; increases in total root length, activities of superoxide dismutase and catalase, and leaf water content; and decreases in leaf water potential, levels of Oand HO, and malondialdehyde content under drought. Under treatments with foliar spraying with abscisic acid (ABA), drought tolerance of both transgenic line Y7-1 overexpressing ZmPMP3g and wild type Ye478 was enhanced, of which Y7-1 showed an increased endogenous ABA and decreased endogenous gibberellin (GA) 1 (significantly) and GA3 (very slightly but not significantly) and Ye478 had a relatively lower ABA and no changes in GA1 and GA3. ZmPMP3g overexpression in Y7-1 affected the expression of multiple key transcription factor genes in ABA-dependent and -independent drought signaling pathways. These results indicate that ZmPMP3g overexpression plays a role in maize drought tolerance by harmonizing ABA-GA1-GA3 homeostasis/balance, improving root growth, enhancing antioxidant capacity, maintaining membrane lipid integrity, and regulating intracellular osmotic pressure. A working model on ABA-GA-ZmPMP3g was proposed and discussed.

摘要

编码含有质膜蛋白脂蛋白 3（PMP3）结构域的蛋白的基因对非生物胁迫有反应，但它们在玉米耐旱性中的功能在很大程度上仍然未知。在这项研究中，过表达玉米 ZmPMP3g 基因的转基因玉米品系表现出增强的耐旱性；总根长、超氧化物歧化酶和过氧化氢酶活性增加，叶片含水量降低；叶片水势、O 和 HO 水平以及丙二醛含量降低。在叶片喷施脱落酸（ABA）的处理下，过表达 ZmPMP3g 的转基因系 Y7-1 和野生型 Ye478 的耐旱性都得到了增强，其中 Y7-1 表现出内源性 ABA 增加，内源性赤霉素 1（显著）和赤霉素 3（非常轻微但不显著）减少，而 Ye478 的 ABA 相对较低，GA1 和 GA3 没有变化。ZmPMP3g 在 Y7-1 中的过表达影响了 ABA 依赖和非依赖干旱信号通路中多个关键转录因子基因的表达。这些结果表明，ZmPMP3g 的过表达通过协调 ABA-GA1-GA3 稳态/平衡、促进根系生长、增强抗氧化能力、维持膜脂完整性和调节细胞内渗透压来发挥作用。提出并讨论了一个关于 ABA-GA-ZmPMP3g 的工作模型。
