Other claims from this paper (13)
- Observation MTD had K(m) of 54.5 mM mannitol.
- Observation MTD had V(max) of 0.47 μmol h⁻¹ mg⁻¹ protein.
- Observation The corresponding cDNA was cloned and named OeMTD1.
- Association OeMTD1 expression correlated with MTD activity.
- Association OeMTD1 expression correlated with OeMaT1 expression.
- Association OeMTD1 expression correlated with carrier-mediated mannitol transport.
- Observation Sucrose-grown cells had only residual OeMTD activity despite high transcription.
- Mechanism OeMTD shows transcriptional and post-transcriptional regulation.
- Intervention effect Na+ repressed MTD activity and OeMTD1 expression.
- Intervention effect K+ repressed MTD activity and OeMTD1 expression.
- Intervention effect PEG repressed MTD activity and OeMTD1 expression.
- Intervention effect Salt significantly increased mannitol transport activity and OeMaT1 expression.
- Mechanism The authors infer olive stress coping involves coordinated mannitol transport and metabolism.
