Bacterial L-forms require peptidoglycan synthesis for cell division

Article Abstract:

The division of L-forms (cell-wall-less bacterial variants) in the absence of cell wall synthesis is been a mystery since septum formation is an essential requisite for cell division. Genetic and biochemical evidence indicates that E. coli L-forms induced by beta-lactam antibiotics do contain small amounts of peptidoglycan, essential for their growth and probably required for septum formation.

Multicellular redox regulation: Integrating organismal biology and redox chemistry

Article Abstract:

The aspects of redox regulation are examined. The mitochondrion-rich multicellular structures are able to emit variable amounts of redox-related signals such as reactive oxygen species (ROS) in response to environmental signals.

Control of asymmetric cell divisions: will cnidarians provide an answer?

Article Abstract:

Cells in the basal metazon phylum Cnidaria are characterized by remarkable plasticity in their differentiation capacity. A glimpse of the complexities of asymmetric cell divisions in a basal metazon animal is provided.
