Description: | Ethylene has been regarded as a stress hormone to regulate myriad stress responses. But how ethylene signaling is involved in the salt stress is poorly understood. To dissect the underlying molecular mechanisms, we performed transcriptome profiling of transgenic plants overexpressing EIN3 (EIN3ox), ein3eil1 double mutant and wild type Col-0. EIN3 and EIL1 are two key transcription factors in ethylene signaling pathway. For this analysis, 5-d-old seedlings treated with or without 200 mM NaCl for 6 h were used for RNA preparation. This design enabled us to examine the overlap in expression pattern among these plants, as well as to identify salt-induced and EIN3/EIL1-dependent genes. |
