[PECULIAR PROPERTIES OF SOME COMPONENTS OF MORPHOLOGICAL STRUCTURE IN A PLANT CELL VACUOLE REVEALED BY CONFOCAL MICROSCOPY].
Results of investigations of peculiar properties related to the structure of plant cell vacuolar membranes are discussed. The study was carried out using confocal microscopy, which allowed us in the process of scanning to identify membrane tubes and vesicules in the preparations of isolated vacuoles. Such membrane tubes were found both inside and outside the vacuoles, and, in the case of scanning intermittently at equal time intervals, transition of vesicles with the membrane tube was observed. Furthermore, scanning of isolated vacuoles was conducted at various distances from the glass substrate. Each time, in the upper area of the isolated vacuole lying on the substrate, we observed a large segment of vacuolar membrane and registered the effect of highly intensive fluorescing of some of membrane segments. The distributions of laurdan fluorescence generalized polarization (GP) values for the vacuolar membrane on the whole and for the intensively fluorescing membrane segments have been obtained. We have found that the microviscosity of the intensively fluorescing membrane segments essentially differs from that of the rest part of the membrane.
