Other claims from this paper (14)
- Intervention effect Copper reduced grape cell growth above 100 µM in a dose-dependent manner.
- Intervention effect Copper reduced grape cell viability above 100 µM in a dose-dependent manner.
- Observation Copper accumulated in specific metal ion sinks in grape cells.
- Observation Grape cell copper transport had K(m) 583 µM.
- Observation Grape cell copper transport had V(max) 177 × 10(-6) %ΔF min(-1) protoplast(-1).
- Association Copper availability regulated the grape cell transport system.
- Intervention effect Ca(2+) stimulated the grape cell transport system.
- Intervention effect Zn(2+) inhibited the grape cell transport system.
- Mechanism Vacuolar Cu(2+) compartmentation depended on a proton gradient generated by V-H(+)-ATPase and V-H(+)-PPase.
- Intervention effect High copper decreased the proton gradient generated by V-H(+)-ATPase.
- Association CuSO(4) availability distinctly affected VvCTr1 expression.
- Association CuSO(4) availability distinctly affected VvCTr8 expression.
- Observation VvCTr1 was highly expressed in green grape berries.
- Observation VvCTr8 was highly expressed in green grape berries.
