Other claims from this paper (7)
- Observation Superoxide accumulates in the Arabidopsis root meristem.
- Observation Hydrogen peroxide accumulates in the Arabidopsis root elongation and differentiation zone.
- Mechanism The balance of superoxide and hydrogen peroxide controls root cell proliferation.
- Observation HD-ZIP III defective mutants alter root growth rates and ROS levels.
- Observation A PHB gain-of-function mutant had short roots and a small meristem.
- Observation Multiple loss of HD-Zip function yielded a bigger root meristem.
- Observation Gain- and loss-of-function HD-Zip mutants had contrasting ROS balances.
