The relative centrifugal field (g), RCF, which is the ratio of the centrifugal
acceleration at a specified radius and the speed to the standard acceleration of gravity,
can be calculated from the following equation:

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)

Instructive interaction

It occur where the responding cell has a choice of fates and will follow one developmental pathway following induction and an alternative pathway in absence of the inductive signal.
