Isoperoxidases in root callus cultures

In this study, four-week-old calli derived from seedling root of sweet corn and r2 r2 stock were analyzed for their isoperoxidases by adopting standard polyacrylamide gel electrophoretic (PAGE) technique. The isozymes of 0.165, 0.47 and 0.87 were common for both the inbred lines. The isoperoxidases with Rf values of 0.09, 0.25, 0.43 and 0.81 were observed in the sweet corn line, whereas r2 r2 exhibited different isoperoxidases with Rf values 0.14, 0.52 and 0.74, suggesting that the genotypic differences in isoperoxidases also exist in callus cultures.
