Cell line selection is one of the traditional and effective approaches to enhancing metabolite accumulation, and biochemical studies provide the fundamental information for the intentional regulation of secondary metabolism in plant cells. In a carrot suspension culture regulated by 2,4-dichlorophenoxyace-tic acid, Ozeki et al. [7] found that there was a correlation between anthocyanin synthesis and morphological differentiation for somatic embryogenesis they also demonstrated the induction and repression of phenylalanine ammonia lyase (PAL) and chalcone synthase correlated with formation of the respective mRNAs. Two biosynthetic enzymes, i. e., PAL and 3-hydroxymethylglutaryl-CoA reductase, were also related with shikonin formation in Lithospermum erythro-rhizon cultures [8]. 

Fig. 9.11 In the DNA of vertebrates, a proportion of the cytosines in the CG sequence are methylated. The DNA methylation pattern is faithfully maintained in the course of embryogenesis and cell differentiation, because normally the discriminating, selective action of the methyltransferase maintains the pattern of DNA methylation. once it is established. Not so in imprinted genes, for which the lack of a methylating enzyme is thought to be responsible. (This information is from ref. 42.
