Studies of cells in interphase and prophase show that at all stages of the mitotic cycle in the nuclei of Einkorn wheat and onion root tips the arrangement of the chromosomes bears a definite relation to the axis of the nucleus. The establishment, by the centromeres, of the metaphase plate ...
Mitosis in onion cells of the root meristem. In the central rowof cells there is a prophase cell showing chromosomes. Below a typical anaphase can be seen. Light microscope micrograph.,站酷海洛,一站式正版视觉内容平台,站酷旗下品牌.授权内容包含正版商业图
Mitosis is a process that occurs during thecell cycle.The role of mitosis in the cell cycle is to replicate the genetic material in an existing cell—known as the “parent cell”—and distribute that genetic material to two new cells, known as “daughter cells.”In order to pass its genet...

In our recent paper, we have quantified the distribution of clathrin-coated pits and vesicles as well as of secretory structures during PPB formation of epidermal cells of onion cotyledons using a combination of high-pressure freezing and dual-axis electron-tomography techniques. Our results ...
In root tip cells of maize, the CDC2 homologue is predominantly localized in the nucleus, with the exception of the nucleolus [11]; in alfalfa cell suspension cells, CDC2MsA is exclusively localized in the nucleus of S phase- and G2 phase-arrested cells [12]; in onion root tip cells ...

Cytoplasmic microtubules of animal cells catastrophically depolymerize upon entry into mitosis but in higher plants there is a longer transition during which cortical microtubules form an increasingly narrow preprophase band, and the chromatin gradually condenses. Progression towards mitosis in onion root ...
monoclonal antibody raised against the PSTAIR sequence, which corresponds to a peptide conserved in the p 34 cdc2 protein kinase throughout the phylogenetic scale including higher plants, was used to study the intracellular localization of p 34 cdc2 during the cell cycle in onion root tip cells....
Changing patterns of tubulin immunofluorescence as onion root meristematic cells progress from a mature pre-prophase band (PPB) stage into mitosis are reported here. The PPB reaches its narrowest profile at maturity and then remains the same width throughout the rest of the transition. Concomitant ...
