The ethylene response factor (ERF) plays a key role in the transcriptional regulation of plant growth, development, and response to various environmental perturbations. Study of ERF transcription factors, especially those in cultivated crops, could facilitate their molecular genetic modification. In this study, an ERF1 gene, designated as ZmERF1, which was found to be localized in the nucleus, was isolated from popcorn (Zea mays L.). Further analysis showed that the ZmERF1 proteins could bind to the GCC box motif and act as a transcriptional activator. A clear picture of ZmERF1 expression pattern showed that ZmERF1 expression varies during different development stages of endosperm. Furthermore, its expression could be highly induced by salinity, osmotic and heat stress, suggesting that the gene is involved in stress signaling pathways in maize. Therefore, ZmERF1 could play important role in abiotic stress tolerance and endosperm development in maize.
