Abstract:

Shoot branching is important for plant adaptation, survival competition and grain yield formation.Recent evidences suggest that phytohormonal signals play a critical role in controlling shoot branching. This review covers the synergistic regulatory roles for auxin, cytokinin and strigolactone in shoot branching in higher plants. The information will be useful for further understanding the regulating mechanism of shoot branching.

Key words: auxin; cytokinin; shoot branching; strigolactone
