Identify the correct sequence of events in cytokinin signaling pathway.
(His= Histidine; AHP = Arabidopsis thaliana histidine phosphotransfer protein)
1
Recpetor binding →phosphorylation of AHP→ phosphorylation of an aspartate residue → activation of His kinase
2
Receptor binding→ phosphorylation of AHP→ activation of His kinase →phosphorylation of an aspartate residue
3
Receptor binding→→ activation of His kinase→ phosphorylation of AHP
4
Receptor binding→ activation of His kinase→ phosphorylation of an aspartate residue→ phosphorylation of AHP
