[Conformational fluctuations in chloroplasts]

Characteristic features of conformational changes in chloroplasts have been studied by microfilm technique at BMI-13 installation. The oscillatory character of changes in chloroplast cross-section area in time, determined earlier by the tele-lazer microscopy technique, has been confirmed by our data. When chloroplasts are simultaneously seen in the microscope it is possible to observe their synchronous oscillation. The stationarity check of conformational changes shows that is a non-stationary process in the general case. So it is concluded that the standard technique of analysing accidental non-stationary processes can be used for study of conformational changes in chloroplasts provided that the corresponding parts of their kinetics are selected or trends are eliminated depending on the type of non-stationarity.
