Long-distance transport of three hormones that regulate shoot branching: auxins, cytokinins, and strigolactones. Auxin is produced primarily in young expanding leaves and is transported basipetally by PIN1- mediated polar auxin transport.

Brassinosteroids are synthesized from the plant sterol campesterol, which is similar in structure to cholesterol. Members of the cytochrome P450 monooxygenase (CYP) enzyme family that are associated with the ER catalyze most of the reactions in the brassinosteroid biosynthesis pathway.

Mevalonic acid serves as a precursor of the triterpenoid pathway and is condensed and transformed to 2,3-oxidosqualene which further undergoes modification to form major plant sterols like sitosterols and campesterols.
