Three main classes of mutations affecting plant height have
been selected:
1. Gibberellin-insensitive dwarfs
2. Gibberellin-deficient mutants in which the gibberellin deficiency has been overcome by a second “suppressor” mutation, so the plants look closer to normal
3. Mutants with a constitutive gibberellin response (“slender” mutants)
