Abstract Background The bZIP class Abscisic acid Responsive Element ABRE -binding factor OSBZ8 kD has been considered to regulate ABA-mediated transcription in the suspension cultured cells of japonica rice. Still nothing is known about the expression of OSBZ8 at protein level in vegetative tissue of salt sensitive and salt tolerant rice plants. In our previous study Electrophoretic Mobility Shift Assay EMSA of 32P ABRE-DNA and nuclear extracts prepared from the lamina of Pokkali rice plants has detected the presence of an ABRE-binding factor. Northern analysis has also detected salinity stress induced accumulation of transcripts for bZIP class of factor. Therefore OSBZ8 was considered to play an important role in the regulation of transcription in the vegetative tissue of rice. The aim of this study is to find out whether OSBZ8 has any
