The ERF transcription factor EPI1 is a negative regulator of dark-induced and jasmonate-stimulated senescence in .

Identification of the factors involved in the regulation of senescence and the analysis of their function are important for both a biological understanding of the senescence mechanism and the improvement of agricultural productivity. In this study, we identified an gene termed " (EPI1) as a possible regulator of senescence in . We found that EPI1 possesses transcriptional repression activity and that the transgenic plants overexpressing and expressing its chimeric repressor, , commonly suppressed the darkness-induced senescence in their excised aerial parts.
