Arabidopsis thaliana ethylene-responsive element binding protein (AtEBP), an ethylene-inducible, GCC box DNA-binding protein interacts with an ocs element binding protein.

ABSTRACT: Ocs elements are a group of promoter sequences required for the expression of both pathogen genes in infected plants and plant defense genes. Genes for ocs element binding factors (OBFs), belonging to a specific class of basic-region leucine zipper (bZIP) transcription factors, have been isolated in a number of plants. Using protein-protein interaction screening with OBF4 we have isolated AtEBP, an Arabidopsis protein that contains a novel DNA-binding domain, the AP2/EREBP domain. One class of proteins that contain this domain are the tobacco ethylene-responsive element binding proteins (EREBPs). The EREBPs bind the GCC box that confers ethylene responsiveness to a number of pathogenesis related (PR) gene promoters. AtEBP expression is inducible by exogenous ethylene in wild-type plants an
