Cell wall assembly in Bacillus megaterium: incorporation of new peptidoglycan by a monomer addition process [PDF]

, 1991
The pattern of cross-linking in the peptidoglycan of Bacillus megaterium has been studied by the pulsed addition of radiolabeled diaminopimelic acid.

Simulations suggest a constrictive force is required for Gram-negative bacterial cell division

Nature Communications, 2019
It is unclear whether a constrictive force is exerted on the membrane from inside during bacterial cell division, or cell wall remodeling alone drives membrane constriction from outside.

Divergent Cell Wall Remodelling in Maize Under Cold or Drought

Plant Stress
The plant cell wall is the first line of defense against environmental changes. We previously described that the maize B73 is a stalk-lodging resistant inbred that undergoes extensive modifications in general physiology and cell wall composition under ...

Evolution of Cell Wall Polymers in Tip-Growing Land Plant Gametophytes: Composition, Distribution, Functional Aspects and Their Remodeling

Frontiers in Plant Science, 2019
During evolution of land plants, the first colonizing species presented leafy-dominant gametophytes, found in non-vascular plants (bryophytes). Today, bryophytes include liverworts, mosses, and hornworts. In the first seedless vascular plants (lycophytes)

Remasking of Candida albicans β-Glucan in Response to Environmental pH Is Regulated by Quorum Sensing

mBio, 2019
Candida albicans is a commensal yeast of the human gut which is tolerated by the immune system but has the potential to become an opportunistic pathogen. One way in which C.

The Glycosylphosphatidylinositol-Anchored DFG Family Is Essential for the Insertion of Galactomannan into the β-(1,3)-Glucan–Chitin Core of the Cell Wall of Aspergillus fumigatus

mSphere, 2019
The fungal cell wall is a complex and dynamic entity essential for the development of fungi. It is composed mainly of polysaccharides that are synthetized by protein complexes.

The Dynamic Remodeling of Plant Cell Wall in Response to Heat Stress

Genes
Heat stress has a significant negative impact on plant growth, development, and yield. The cell wall, a key structural feature that sets plants apart from animals, not only acts as the first physical barrier against heat stress but also plays an active role in the heat stress (HS) response through signaling pathways.

Role of the cell-wall structure in the retention of bacteria by microfiltration membranes [PDF]

, 2009
This experimental study investigates the retention of bacteria by porous membranes. The transfer of bacteria larger than the nominal pore size of microfiltration track-etched membranes has been studied for several kinds of bacterial strains.
