Other claims from this paper (11)
- Intervention effect Excess copper (50 microM) severely reduced root growth in wheat relative to control plants.
- Intervention effect Excess copper (50 microM) increased K(+) ion leakage from wheat roots.
- Intervention effect Excess metal supply decreased the total lipid content of wheat root plasma membrane.
- Intervention effect Excess metal supply increased the phospholipid amount of wheat root plasma membrane.
- Intervention effect Excess metal supply reduced steryl lipids in wheat root plasma membrane.
- Intervention effect Only excess copper decreased the lipid to protein ratio of wheat root plasma membrane relative to the control.
- Intervention effect Only excess copper lowered the phosphatidylcholine to phosphatidylethanolamine ratio of wheat root plasma membrane relative to the control.
- Intervention effect Copper depletion decreased the degree of unsaturation of wheat root plasma membranes, and more so after 50 microM Cu supply.
- Intervention effect Copper deficiency and excess increased NADPH-dependent superoxide-producing oxidase activities in wheat root plasma membranes.
- Intervention effect Membrane-bound lipoxygenase was not increased or activated by Cu treatments in wheat roots.
- Intervention effect Copper depletion in the growth solution had only a slight effect on the plasma membrane lipid composition of wheat roots.
