Shoot branching plays an important role in determining plant architecture.
SLs also act as plant hormones to regulate shoot branching (Domagalska and Leyser 2011).
The architecture of the shoot branching system in Poaceae defines the growth forms within this family.
Shoot branching (tiller) is regulated by plant hormones, particularly cytokinins (CKs) and strigolactones (SLs).
Shoot branching is a major factor in plant architecture and an important agronomic trait for productivity.
In tomato, the regulatory mechanisms of shoot branching patterns have been studied mainly in mutants defective in meristem identity.
Strigolactones (SLs) negatively regulate shoot branching, and can respond to conditions of low or absent phosphate or nitrogen.
To investigate the roles of D14 in shoot branching of chrysanthemum, we isolated the D14 homolog DgD14.
Acropetal transport of cytokinin (toward the shoot apex) has also been implicated in the control of shoot branching [6].
Recent studies of highly branched mutants revealed that SL or its metabolites work as a phytohormone to inhibit shoot branching.
Tillers are produced by shoot branching and is a two-stage process comprising the formation of an axillary bud at each leaf axil and its subsequent outgrowth.
