Effects of lanthanum chloride on activity of redox system in plasma membrane of rice seedling roots
- 生命科学－已发表论文 
The plasma membrane was isolated and purified by using the method of aqueous two-phase partitioning from rice ( Oryza sativa) seedling roots. The effect of LaCl3 on the activity of redox system of plasma membrane has been studied. The reduction rate of Fe(CN)(6)(3-) and the oxidation rate of NADH in plasma membrane are stimulated below the concentration of 40 mumol (.) L-1, but depressed in pace with the increasing of LaCl3 over the concentration of 40 mumol (.) L-1. The possible effect of LaCl3 on the uptake of Fe element by rice seedling was also discussed.
