Gibberellin is an important plant hormone that regulates
several aspects of plant growth and development. Some statements are given
below in relation to signalling
pathways:
a) The binding of gibberellin (GA) to its receptor leads to
the degradation of the DELLA repressor by the 26S proteasome
b) Gibberellin binds to the GID1 receptor and induces a
conformational change in the N-terminal domain of the receptor, allowing the
receptor to interact with the TVHYNP and DELLA domains of the DELLA repressor
c) The formation of the GID1-repressor complex promotes the
interaction between the repressor and the E3 ubiquitin ligase SCFTIR1 complex,
leading to the ubiquitination and degradation
d) The gibberellin receptor GIBBERELLIN INSENSITIVE DWARF 1
(GID1) also itself function as an F-box protein
Which one of the following is the incorrect statements about GA signalling pathway;
