The results suggested that the tolerance of the wheat seedlings to osmotic stress was associated with the activity of H+-ATPase and the contents of NCC-Spd and NCC-Spm and CC-Put and CC-Spd in PM of the seedling roots.

• 暗示了渗透胁迫下，小麦幼苗根核蛋白体上NCC一Spm、NCc一Spd、pIScC一put和pISCC一Spd水平的上升可能通过维持核蛋白体构象和功能的稳定以及调节基因的表达而增强幼苗适应渗透胁迫的能力。
