How do brassinosteroids fit in bud outgrowth models?

A network of plant hormonal signals coordinates plant branching. Brassinosteroids are important in this network, acting as repressors of the strigolactone pathway and .

The Strigolactone Pathway Is a Target for Modifying Crop Shoot Architecture and Yield.

Due to their sessile nature, plants have developed the ability to adapt their architecture in response to their environment. Branching is an integral component of plant architecture, where hormonal signals tightly regulate bud outgrowth. Strigolactones (SLs), being a novel class of phytohormone, are known to play a key role in branching decisions, where they act as a negative regulator of bud outgrowth.
