- Аннотация: The article presents the details of the process of structural organization, formation and disassembly of the nucleolus, chromatin condensation during the passage of the cell cycle studied by the method of classicaltransmission electron microscopy (TEM)in the cells of the meristematic zone of the wheat root.The transformations of peripheral chromosome material (PCM) in telophase,thetransformations of the nucleolar nucleolonemain the interphase and prophase,andthe chromatin transformations(condensation and decondensation)were studied and analyzedunder the conditions of the geomagnetic field, weakened magnetic field and staticmagnetic field.Using an analysis of the dynamics of structural transformations of proliferating nuclei,we observeda disturbancein the formation of the chromonema and condensed chromatin in the middle interphase, a change in the structural organization of the nucleolus during the transition from late interphase to prophase, as well as a change in the structure of PCM, pre-nucleolus and chromatin in telophase.A schemafor the generationof a specificconformation ofnucleolonemaand chromonemaand its influence on the structural organization of chromosomes in anaphase and telophasewas proposed.The nature of this structure is discussed. Possiblemechanisms oftheeffect ofmagnetic field on the nuclear compartment, regulation of chromatin decompactization, export of pre-ribosomal particles under stress, and the fine structure of the nucleolonemaare considered.
