Other claims from this paper (14)
- Observation A genome-wide analysis identified 20 SOD genes in wheat.
- Intervention effect TaSOD7-4A overexpression in wheat significantly increased antioxidant enzyme activity.
- Intervention effect TaSOD7-4A overexpression improved drought tolerance in transgenic wheat lines.
- Mechanism TaPHL7 was identified as an upstream transcriptional regulator of TaSOD7-4A.
- Mechanism TaPHL7 directly binds to the TaSOD7-4A promoter and activates its expression.
- Observation The TaPHL7 protein is localized to the nucleus.
- Observation TaPHL7 has transcriptional activation activity, mapped to its C-terminal region.
- Intervention effect Under drought stress, TaPHL7 overexpression significantly improved drought tolerance in transgenic wheat.
- Intervention effect TaPHL7 overexpression lowered H2O2 and MDA contents under drought stress.
- Intervention effect TaPHL7 overexpression increased relative water content under drought stress.
- Intervention effect TaPHL7 overexpression increased proline accumulation under drought stress.
- Intervention effect TaPHL7 overexpression enhanced antioxidant enzyme activity under drought stress.
- Intervention effect TaPHL7 RNA interference wheat lines showed increased MDA content.
- Intervention effect TaPHL7 RNA interference wheat lines showed decreased proline levels.
