| Abstract: | In this study we analysed the terminal step of cytoskeleton cycle in higher plant meiosis: transition from phragmoplast to radial interphase configuration. Wild type meiosis in a range of mono- and dicotyledonous species was studied. A number of cytoskeleton abnormalities on this stage was described in meiotic mutants, haploids and wide hybrids of various species. We described processes of cytoskeleton rearrangements on this stage: disjunction of phragmoplast MTs, their shortening and the role of daughter cell membranes. The independence of the interphase radial MT system formation from the previous steps of cytoskeleton cycle and from nuclear envelope cycle is proposed. |
