Endocytosis of cell surface material mediates cell plate formation during plant cytokinesis.
Dividing plant cells perform a remarkable task of building a new cell wall within the cytoplasm in a few minutes. A long-standing paradigm claims that this primordial cell wall, known as the cell plate, is generated by delivery of newly synthesized material from Golgi apparatus-originated secretory vesicles. Here, we show that, in diverse plant species, cell surface material, including plasma m...
متن کاملVery-long-chain fatty acids are required for cell plate formation during cytokinesis in Arabidopsis thaliana.
Acyl chain length is thought to be crucial for biophysical properties of the membrane, in particular during cell division, when active vesicular fusion is necessary. In higher plants, the process of cytokinesis is unique, because the separation of the two daughter cells is carried out by de novo vesicular fusion to generate a laterally expanding cell plate. In Arabidopsis thaliana, very-long-ch...
متن کاملThe cell plate in bacterial cytokinesis.
The first phase of bacterial cytokinesis was described by Knaysi (1951) as involving an inward growth of the cytoplasmic membrane to form a septum across the cell. Transverse plasma rnembranes or boundaries were previously reported by Migula (1894) in Bacillus oxalaticus, by Guillermond (1908) in Bacillus mycoides, by Knaysi (1930) in B. mycoides and Bacillus mesentericus, and by Robinow (1942,...
متن کاملA role of endocytosis in plant cytokinesis.
The preprophase band (PPB) of microtubules (MTs) marks the site of the future division plane irrespective of the orientation of the equatorial plane. Because the PPB MTs disappear during prometaphase, some positional information is thought to remain in the cortical cytoplasm after the disappearance of the PPB MTs. Cytoskeletal proteins are known to be excluded from the PPB site during mitosis. ...
متن کاملVesicle Dynamics during Plant Cell Cytokinesis Reveals Distinct Developmental Phases.
Cell division in plant cells requires the deposition of a new cell wall between the two daughter cells. The assembly of this plate requires the coordinated movement of cargo vesicles whose size is below the diffraction-limited resolution of the optical microscope. We combined high spatial and temporal resolution confocal laser scanning microscopy with advanced image-processing tools and fluores...
