Distribution patterns of phosphorylated Thr 3 and Thr 32 of histone H3 in plant...
Caperta, A.; Rosa, M.; Delgado, M.; Karimi, R.; Demidov, D.; Viegas, Wanda; Houben, A.Cell cycle dependent phosphorylation of conserved N-terminal tail residues of histone H3 has been described in both animal and plant cells. Through cytogenetic approaches using different plant species we show a detailed description of distribution patterns of phosphorylated histone H3 at either threonine 3 or threonine 32 in mitosis and meiosis. In meristematic cells of the large genome species Secale cereale, ...
Cochicine-induced polyploidization depends on tubulin polymerization in c-metap...
Caperta, A.; Delgado, M.; Ressurreição, F.; Meister, A.; Jones, R.N.; Viegas, W.; Houben, A.The microtubule cytoskeleton plays a crucial role in the cell cycle and in mitosis. Colchicine is a microtubule-depolymerizing agent that has long been used to induce chromosome individualization in cells arrested at metaphase and also in the induction of polyploid plants. Although attempts have been made to explain the processes and mechanisms underlying polyploidy induction, the role of the cytoskeleton still...
