Effects of virus infection on expression of cell cycle regulatory proteins in the unicellular marine algae Emiliania huxleyi The authors have investigated the biochemical events by which marine algal virus infection induces cell cycle arrest. The key G2/M-phase regulat......
coliandB. subtilis, tightly regulate cell cycle progression to achieve consistent cell size distributions and replication dynamics. Many of the hallmark features of these model bacteria, including lateral cell wall elongation and symmetric growth and division, do not occur in mycobacteria. Instead, ...
Thus, in some stem or cancer cells, cell cycle duration has already been followed as a marker of asymmetric cell divisions giving rise to cells with specific cell fates10,11,12. However, whether the variability of cell cycle duration, which is observed in many cell types, itself reflects ...

This variable part is contained entirely within G1, may be controlled hormonally by the organism, and is assumed to result from a single first order random process that terminates the variable part of the cell cycle with constant probability. As originally proposed, the model failed to account ...
(Saunders et al.2010). Inactivating TOR pathway arrests the cell cycle in G2 phase, which is required for autophagy and appressorium formation. Nutrients recycled from autophagy reactivate the TOR pathway to reinitiate cell cycle progression. Due to the re-inactivation of the TOR pathway, the...
Cell membrane formation during the cellularization of the syncytial blastoderm of Drosophila. The early blastoderm of Drosophila is a syncytium in which about 6000 nuclei become localized in the peripheral cytoplasm. During cycle 14 interphase, a wa... Loncar,S J,Singer - 《Proceedings of the...
Daughter cells of the chlorococcal alga Scenedesmus quadricauda incubated under photosynthesizing conditions in a phosphate-free medium accomplished one cell cycle but divided into a lower number of daughter cells compared to the control. RNA synthesis was restricted early in the cell cycle while prot...
Each of the different cyclin-Cdk complexes serves as a molecular switch that triggers a specific cell-cycle event. We now consider how these switches initiate such events and how the cell-cycle control system ensures that the switches fire in the correct order and only once per cell cycle. ...
