Other claims from this paper (8)
- Observation WOX11 is expressed in emerging crown roots and later in cell division regions of the root meristem in rice.
- Intervention effect Exogenous auxin or cytokinin induces WOX11 expression in rice.
- Intervention effect Loss-of-function or downregulation of WOX11 reduced the number and growth rate of rice crown roots.
- Intervention effect WOX11 overexpression induced precocious crown root growth in rice.
- Observation WOX11 overexpression produced crown roots at the upper stem nodes and the base of florets in rice.
- Intervention effect WOX11 overexpression and RNA interference affected expression of auxin- and cytokinin-responsive genes in rice.
- Association WOX11 directly represses RR2, a type-A cytokinin-responsive regulator gene in rice.
- Mechanism WOX11 may integrate auxin and cytokinin signalling that feeds into RR2 to regulate cell proliferation during crown root development in rice.
