Fig. 5 Gene expression of GST homologues in callus cultured for 4 hrs (dark brown bars, tissue 1.2) or for 72 hrs (light brown bars, tissue 1.3) compared to cells before transfer to PGR-free medium (tissue 1.1) presented as x-fold-change. Positive values describe up-regulation while negative values describe down-regulation.
