Abstract
The results of the experiment which the different concentrations of calmodulin antagonist-CPZ were supplied to 1/2 Hoagland cultural solution showed that CPZ inhibited the uptake of nitrate and its transformation into organic nitrogen in wheat seedlings, and the root was more sensitive to CPZ than the leaf. Finally, CPZ resulted in the decrease of dry weight of root and upground parts of wheat seedlings. CPZ caused the increase of total calcium content in wheat seedlings. The results indicated that calmodulin, as a member of the second messenger system, probably plays an important role in regulation of nitrogen assimilation in plants.
