The invention discloses a kandelia candel (L.) druce ERF (ethylene-responsive element binding factor) transcription factor as well as an encoding gene, an expression vector and application thereof. In the invention, the nucleic acid sequence of the ERF transcription factor cDNA separated from mangrove plant kandelia candel (L.) druce is as shown in SEQ ID No.1. After the ERF transcription factor cDNA is transformed to tobacco, the contents of osmoregulation substances (such as proline) of a transgenic plant are obviously increased, and the salt tolerance of the transgenic plant is obviously improved. An experimental result indicates that the ERF transcription factor can response an adverse signal, thereby effectively improving environmental stress resistances of the plant such as salt and base resistance, diseases and pets resistance and the like. |
