Highly purified plasma membrane vesicles were isolated by aqueous two-phase partitioning from wheat(Triticum sativum L) seedling roots,and then the activities of H+-ATPase and redox system in plasma membranes were determined.
两相法分离纯化小麦(Triticum sativum L)根细胞质膜微囊用于测定La3+和Eu3+对质膜H+-ATPase及氧化还原系统活性的影响。
The results indicated that under high light intensity ammonium treatment,compared with nitrate treatment,significantly decreased root biomass and root vigor,and significantly enhanced the activity of H+-ATPase and redox system of root plasmalemma,which resulted in the increase of the proton extrusion of roots simultaneously.
供应铵态氮植株根系质膜H+-ATPase和氧化还原系统活性显著高于供应硝态氮植株,且强光下差异更大,根系质子分泌速率也相应增加。
Some properties of plasma membrane redox systems in two spring wheat leaves and their responses to gradual field drought were investigated.
