Possible posttranslational modification, and its genetic control, in flax genotroph isozymes.
Environmentally induced flax genotrophs L and S show heritable shifts in the relative mobilities of peroxidase, esterase, and acid phosphatase isozymes, plus a number of nonspecific glycoproteins. All L isozymes migrated faster than corresponding S isozymes in 10% acrylamide gels. Various aspects of these shifts are reviewed here; it is proposed that posttranslational modification, probably of the carbohydrate moieties of these glycoproteins, underlies the shifts. This proposal is discussed in relation to the switch model for genotroph induction.
