title: Adenilate pool and thylakoid ATP-synthase content in pea leaves under clinorotation.
abstract: It is known that plant resistance to stress factors is connected with energy metabolism. The energy stored in the process of photophosphorylation in the form of ATP is used then to support respiration, transpiration, organic compound synthesis, growth and development as well as to restore cell structure after its damage under extremal environmental factors. Transformation of light energy into chemical energy of ATP is catalyzed by thylakoid membrane enzymatic complex of ATPsynthase-CF1CF0. Its activity and amount in the thylakoid membrane depends on plant growth conditions. The aim of this work was investigation of clinorotation effect on light-induced dynamics of adenyl nucleotides (AMP, ADP and ATP) and estimation of CF1CF0 content in thylakoids of pea leaves grown under slow clinorotation and vertical control.
