Embryogenic cell (EC) suspension cultures derived from mature seed-embryo of rice (Oryza sativa L cv. Kye Hwa) were used for the expression patterns of isozyme and enzyme activity. EC suspension cultures were composed of cells that were densely cytoplasmic, potentially embryogenic. However, nonembryogenic cell (NEC) cultures were composed of large, elongated and vacuolated cells. These cells were analyzed for the isozyme pattern and enzyme activity of EC and NEC. Isozyme patterns of peroxidase, esterase, acid phosphatase and malate dehydrogenase exhibited striking difference in the total number of bands, specificity and intensity of band. Also, these isozymes showed very high activity in the EC. Specific band, band activity and higher enzyme activity of isozyme in EC was absent or low in NEC, which may indicate an association of these specific isozymes with morphological characterization and totipotency of embryogenic cells. These results indicate that specific pattern and activity of enzyme in EC could probably be used as a biochemical marker of EC in rice.n rice.
