Article Synopsis
- Heme oxygenase-1 (HO1) found in animals and plants protects against cell damage from oxidants, and this study focused on the wheat HO1 gene, TaHO1.
- TaHO1 encodes a protein similar to maize HO1 and clusters with other plant HO1-like sequences, showing significant activity in converting heme to biliverdin IXa under optimal conditions.
- The expression of TaHO1 can be triggered by various stress-related compounds, indicating its potential role in helping plants respond to abiotic stresses.
In Arabidopsis thaliana, a family of four genes (HY1, HO2, HO3 and HO4) encode haem oxygenase (HO), and play a major role in phytochrome chromophore biosynthesis. To characterize the contribution of the various haem oxygenase isoforms involved in salt acclimation, the effects of NaCl on seed germination and primary root growth in Arabidopsis wild-type and four HO mutants (hy1-100, ho2, ho3 and ho4) were compared. Among the four HO mutants, hy1-100 displayed maximal sensitivity to salinity and showed no acclimation response, whereas plants over-expressing HY1 (35S:HY1) exhibited tolerance characteristics.
