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.
