| 英文摘要 | The basic helix-loop-helix family of proteins, which function as transcription factors, have been intensively studied in plants and animals. However, the molecular mechanism of these factors contributing to stress tolerance is unknown. Here, We report on the overexpression of OrbHLH001 from Dongxiang wild rice (Oryza rufipogon) conferring salt tolerance in transgenic rice plants. The expression of OrbHLH001 was tissue specific, mainly in phloem tissues throughout the plant. Ion assay with the scanning ion-selective electrode technique showed that NaCl stress has a greater influence on Na+ efflux and K+ influx in OrbHLH001-overexpressed plants than the wild type. OrbHLH001 protein can induce the expression of OsAKT1 to regulate the Na+/K+ ratio in OrbHLH001-overexpressed plants by specifically binding to an E-box motif in the promoter region of OsAKT1. The Mechanism may have potential use in rice molecular breeding. (c) 2012 Elsevier GmbH. All rights reserved. |
