Other claims from this paper (12)
- Method / resource The rapeseed BnHO1 gene was cloned and sequenced.
- Observation BnHO1 showed high homology with Arabidopsis HY1 proteins.
- Observation BnHO1 encodes a 32.6 kDa protein with a 54-amino-acid transit peptide and predicted mature mass of 25.1 kDa.
- Observation Mature BnHO1 expressed in Escherichia coli had haem oxygenase activity.
- Intervention effect Low-dose NaCl upregulated BnHO1 and induced lateral root formation.
- Intervention effect Low-dose PEG upregulated BnHO1 and induced lateral root formation.
- Intervention effect Higher doses of NaCl or PEG produced contrasting responses.
- Intervention effect ZnPPIX significantly blocked the induced and inhibited lateral-root responses.
- Intervention effect Low salinity or osmotic stress induced auxin response factor transcripts and auxin content in seedling roots.
- Intervention effect N-1-naphthylphthalamic acid prevented low-dose NaCl and PEG inducible responses.
- Intervention effect Haemin rescued the inducible responses blocked by the polar auxin transport inhibitor.
- Mechanism The authors infer a role for rapeseed HO-1 in stress-induced lateral root formation with possible auxin signaling interaction.
