1999) reported that although two of three of their lines exhibited silencing of marker genes (uidA in one, and both uidA and bar in another), expression of the HMW-glutenin genes in these same lines was stable over three generations.
5] Moreover; at least one marker gene in use has been found to confer cross-resistance to other commonly used antibiotics, and relatively common mutations in marker genes resistant to antiquated antibiotics can also lead to cross-resistance, to currently useful antibiotics, making a marke r that is presumed safe into a more risky one.
