Other claims from this paper (10)
- Intervention effect pHBA at 0.4 mM suppressed Arabidopsis growth.
- Intervention effect pHBA induced accumulation of NO and H2O2 in Arabidopsis.
- Intervention effect The pHBA-induced NO and H2O2 accumulation was reversed by NO or H2O2 metabolism inhibitors or scavengers.
- Intervention effect pHBA-induced NO and H2O2 accumulation was compromised in NO synthesis mutants noa1, nia1 and nia2.
- Intervention effect Suppressing NO accumulation did not reduce pHBA-induced H2O2 accumulation.
- Intervention effect The inhibitory effect of pHBA on growth was aggravated in NO/H2O2 metabolism-related mutants.
- Intervention effect The inhibitory effect of pHBA on growth was aggravated when NO/H2O2 were reduced by different inhibitors.
- Intervention effect Adding an NO/H2O2 donor partly relieved the inhibitory effect of pHBA on wild-type growth.
- Intervention effect Adding only an NO donor, but not low-concentration H2O2 donor, could relieve the pHBA inhibition of root growth in NO metabolism mutants.
- Mechanism NO and H2O2 are proposed to mediate the Arabidopsis response to pHBA, with H2O2 acting upstream of NO.
