The relationship between energetic parameters and content of stress proteins (alternative oxidase, uncoupling protein and HSP70) in wild grass Elymus sibiricus mitochondria during different stress exposure (cold hardening, cold shock, high-temperature stress, water deficiency and oxidative stress) has been studied. It has been shown that influence of mild stress factors (cold hardening and exogenous 0.5 mM hydrogen peroxide treatment) result in adaptive changes related to the increase of activity alternative oxidase and the increase of content such proteins as alternative oxidase, uncoupling protein and HSP70. The comparative analysis of the function of the cultured and wild plants mitochondria in stress conditions has been produced.
