Bacterial cell shape is defined by an exoskeleton-like structure composed of peptidoglycan (PG). Polymerization and maturation of PG requires certain enzymes called penicillin binding proteins (PBPs). One of these, PBP 3, is recruited to the cell division site by the scaffold-like protein, FtsZ, to synthesize septal PG. FtsZ is the earliest known protein to move to the cell division site, where the protein polymerizes and forms a dynamic ring structure, the Z ring. The Z ring recru...

Light-Dependent Regulation of Cell Division in Ostreococcus: Evidence for a Major Transcriptional Input1[W]
Plant Physiology ; Cell division often occurs at specific times of the day in animal and photosynthetic organisms. Studies in unicellular photosynthetic algae, such as Chlamydomonas or Euglena, have shown that the photoperiodic control of cell division is mediated through the circadian clock. However, the underlying
Three Win Nobel for Medicine; American, Two Britishers Pioneered Work on Cell Division
The Washington Post ; An American and two Britishers, whose pioneering discoveries in the mechanics of cell division could have important implications for cancer treatment, won the Nobel Prize for Physiology or Medicine yesterday. The Nobel Assembly at Sweden's Karolinska Institute announced that Leland Hartwell, of
Auxin-Dependent Cell Division and Cell Elongation. 1-Naphthaleneacetic Acid and 2,4-Dichlorophenoxyacetic Acid Activate Different Pathways1
Plant Physiology ; During exponential phase, the tobacco (Nicotiana tabacum) cell line cv Virginia Bright Italia-0 divides axially to produce linear cell files of distinct polarity. This axial division is controlled by exogenous auxin. We used exponential tobacco cv Virginia Bright Italia-0 cells to dissect early
The (beta)-subunit of the arabidopsis G protein negatively regulates auxin-induced cell division and affects multiple developmental processes
Plant Cell ; Plant cells respond to low concentrations of auxin by cell expansion, and at a slightly higher concentration, these cells divide. Previous work revealed that null mutants of the a-subunit of a putative heterotrimeric G protein (GPA1) have reduced cell division. Here, we show that this prototypical

The Washington Post ; A skinned knee heals. A cancerous tumor grows. An embryo develops into a baby. Underlying all these commonplace events is one of the most extraordinary natural phenomena known to science-the ability of one living cell to transform itself into two living cells. Cell division is the act that has kept
