title: The composition of free fatty acids and mitochondrial activity in seedlings of winter cereals under cold shock.
abstract: Cold shock (-4° C, 1 h) induces qualitative and quantitative changes in the composition of free fatty acids in mitochondria of winter-hardy cereals (Secale cereale L.,Triticum aestivum L.). The amount of these compounds and the degree of their unsaturation increases. Simultaneously, a marked change occurs in the oxidative and phophorylative activities of the mitochondria: respiratory control decreases, respiration in state 4 and antimycin A-resistant respiration increase. The changes in mitochondrial activity are presumed to be caused by endogenous free fatty acids, the amount of which is increased because of phospholipase activity.
