The yeast cell wall is a strong, but elastic, structure that is essential not only for the maintenance of cell shape and integrity, but also for progression through the cell cycle. During growth and morphogenesis, and in response to environmental challenges, the cell wall is remodeled in a highly regulated and polarized manner, a process that is principally under the control of the cell wall in...

This study aims to analyze the influence of fibrils oscillations and connections on effective hygro-elastic behavior wood cell wall. For that, two different models microstructure describing wall are introduced: model 1S, for which allowed oscillate in one direction like a sine curve, 2S, directions as helix. The associated with each is computed by numerical periodic homogenization. Then, we eff...

Previous observations (MUCK, J., AND GLASER, L., Biothem. Biophys. Res. Commun., 39, 699 (1970)) on the turnover of the cell wall of Bacillus subfilis W-23 during logarithmic growth have been extended to show that (a) freshly synthesized wall does not become available for turnover for about one-half to one generation; (b) the turnover rates of the cell wall mucopeptide and cell wall teichoic ac...

The cell wall is one of the characteristic components of plant cells. The cell wall composition differs among cell types and is modified in response to various environmental conditions. To properly generate and modify the cell wall, many proteins are transported to the plasma membrane or extracellular space through membrane trafficking, which is one of the key protein transport mechanisms in eu...

In the simplest sense, cell walls are a carbohydrate and protein structures that surround and separate cells. Perhaps the most familiar cell wall structures are cork and wood, where the cell wall remains after the cells within have degraded. Cotton, the fiber that keeps some of us clothed in our complex world, is also a type of cell wall. These are specialized examples, and it is clear that liv...

Plant cell walls display a considerable degree of diversity in their compositions and molecular architectures. In some cases the functional significance of a particular cell wall type appears to be easy to discern: secondary cells walls are often reinforced with lignin that provides durability; the thin cell walls of pollen tubes have particular compositions that enable their tip growth; lupin ...

Rice is a model plant widely used for basic and applied research programs. Plant cell wall proteins play key roles in a broad range of biological processes. However, presently, knowledge on the rice cell wall proteome is rudimentary in nature. In the present study, the tightly-bound cell wall proteome of rice callus cultured cells using sequential extraction protocols was developed using mass s...
