Some given statements about
the cytokinin signalling pathway;
a) Cytokinin receptor
CRE1 probably functions as a monomer
b) Two other hybrid sensor kinases (AHK2 and AHK3) may also
act as cytokinin receptors in Arabidopsis
c) Activated receptor activates their histidine kinase
activity, The phosphate is transferred to an aspartate residue (D) on the fused
receiver domains
d) The phosphate is then transferred to a conserved
histidine present in an AHP protein that transfer the phosphate to an aspartate
residue located within the receiver
domain of type-B ARRs only
e) The phosphorylation of the type-B ARR activates the
output domain to induce transcription of genes encoding type-A ARRs.
f) The phosphorylated type-A ARRs feed back to negatively
regulate cytokinin signaling, thus dampening cytokinin responses
Which of the following are the correct prediction about cytokinin signalling?
