6.3.2.3 | additional information | construction of gsh2 insertion mutants, the mutants have a seedling lethal phenotype in contrast to the embryo lethal phenotype of gamma-glutamate cysteine ligase, gsh1, EC 6.3.2.2, null mutants, overview. The mutants show hyperaccumulation of gamma-glutamylcysteine to levels 5000-fold that in the wild-type and 200fold wild-type levels of GSH, phenotype, overview. Complementation of gsh2 mutants with the cytosol-specific GSH2 give rise to phenotypically wild-type transgenic plants | Arabidopsis thaliana |
