Cloning and activity analysis of the promoter of nucleotide exchange factor gene ZjFes1 from the seagrasses Zostera japonica.

ABSTRACT: After HSP70 binds to the J domain of the substrate and co-chaperone protein, ATP is hydrolyzed to ADP, and the nucleotide exchange factors (NEFs) promote the release of ADP. Under physiological conditions, the nucleotide exchange step is the rate-limiting step, which is accelerated by NEFs. In this study, the promoter of nucleotide exchange factor ZjFes1 was cloned, and its expression in tissues and under heat stress was studied to understand the regulatory mechanism of ZjFes1 and provide the molecular basis to study heat tolerance mechanism of seagrass. It was found that the promoter has common cis-acting elements in promoter and enhancer regions CAAT-box, as well as light response elements AE-box, Box 4 and TCCC-motif, a cis-acting regulatory element essential for the anaerobic induction
