Annotated Information
Gene Symbol
- Os07g0684900 <=> OsWOX11, Os WOX11, OsWOX12A
Function
- WOX11 is involved in the activation of crown root emergence and growth.
- WOX11 may be an integrator of auxin and cytokinin signaling that feeds into RR2 to regulate cell proliferation during crown root development.
Mutation
- Loss-of-function mutation or downregulation of WOX11 reduced the number and the growth rate of crown roots, whereas overexpression of the gene induced precocious crown root growth and dramatically increased the root biomass by producing crown roots at the upper stem nodes and the base of florets.
- The expressions of auxin- and cytokinin-responsive genes were affected in WOX11 overexpression and RNA interference transgenic plants.
Expression
- WOX11 was found to be expressed in emerging crown roots and later in cell division regions of the root meristem. The expression could be induced by exogenous auxin or cytokinin.
