Dynamics of polyphosphoinositides content in seedlings of winter wheat in response to cold stress

摘要

Effect of 5-60 minutes cold stress on content of polyphosphoinositides in etiolated wheat seedlings (Triticum aestivum L.) was studies. It was shown, that 10 minutes of cold treatment caused the changes in phosphatidylinositol-4,5-bisphosphate and phosphatidylinositol-4-phosphate content in shoots of winter wheat. Than the quantity of polyphosphoinositides returned to control level. It is suggested that the phosphatidylinositol cycle participates in temperature signal transduction.
