Characteristics of cell walls from morphological variants of Escherichia coli.
Two strains (E-26 and B) of Escherichia coli were examined for their growth response in a medium containing 0.75 yo (w/v) NaCl, 1 yo (w/v) L-lysine hydrochloride, 2 % (w/v) glucose, 2.4 % (w/v) nutrient broth, and 5 % (w/v) casein hydrolysate. Strain E-26 grew as a rod which was slightly larger than when it was grown in a defined medium. Strain B grew as a filamentous and branched form; while i...

متن کاملPlant cell walls.
Cell walls are important features of plant cells that perform a number of essential functions, including providing shape to the many different cell types needed to form the tissues and organs of a plant. Forming the interface between adjacent cells, plant cell walls often play important roles in intercellular communication. Because of their surface location, plant cell walls play an important r...

Plant cell wall (CW) polysaccharides are responsible for the mechanical strength and growth of plant cells; however, the high-resolution structure and dynamics of the CW polysaccharides are still poorly understood because of the insoluble nature of these molecules. Here, we use 2D and 3D magic-angle-spinning (MAS) solid-state NMR (SSNMR) to investigate the structural role of pectins in the plan...
متن کاملPlant Cell Walls
The cell wall is the strong, outermost layer of a plant cell, located external to the plasma membrane. The cell wall often far outlives the protoplast which synthesized it. In cork, for example, the wall serves its particular biological role (physical protection of a tree trunk) for many years after the death of the protoplast. However, the walls of living cells are not inert ‘boxes’ but comple...
