Functional Analysis of ERF Gene Associated With Plant Defense in Arabidopsis

Abstract

The DEAR1 (DREB and EAR motif protein 1), which encodes the protein containing DREB domain and EAR motif, is likely to function as a transcriptional repressor to the DREB-binding protein. The DEAR1 overexpressor showed constitutive cell death on rosette-leaves and accelerated leaf senescence. The overexpressor also stimulated PDF1.2 gene which is controlled by ERF (ethylene-responsive element binding factor) genes. The ERF gene under the DEAR1 control will be reported.
