OsWRKY89, a rice WRKY transcription factor gene, is induced by UV-B radiation. To identify the cis-elements in the OsWRKY89 promoter related to UV-B response, the promoter and its deleted fragments were each fused with gus reporter gene and transformed into rice calli. The transgenic plants regenerated were used to analyze their responses to UV-B irradiation. Finally, an UV-B response cis-regulatory element was narrowed to the region of 25 bp between -1 188 and -1 213 upstream the translation start site of OsWRKY89 gene, including nucleotide sequence of AAGATCTACCATTGCTCTATAGCTT. Through analysis of the promoter of OsWRKY89 and 28 genes up-regulated by UV-B treatment, two relatively conserved UV-B response elements in the 1 500 bp protmoter region studied were located. Coincidental, the 25 bp of OsWRKY89 promoter contains one of the conserved elements. Furthermore, several conserved light-response elements including ACE^OsWRKY89, MRE^OsWRKY89 and UVBox^AtANAC13 were also found to adjoine to the 25 bp UV-B response region in the OsWRKY89 promoter, suggesting they together play roles in regulating the light responses of the gene.
