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