Three genes of NsERFs (EREBPs), transcription factors for GCC box of basic PR genes, were isolated from Nicotiana sylvestris. Analyses of transgenic tobacco carrying the NsERF promoter::GUS genes showed that expression of all NsERF genes in leaves was induced by ethylene. Sequence analyses indicated that the 5'-upstream region of NsERF3 gene has the GCC box. In contrast, the promoter regions of NsERF2 and 4 have no GCC box, whereas NsERF2 has a putative EIN3 binding site. Tissue/cell specific expression is also discussed.
