TLDR
Recent discoveries have uncovered how plant cells synthesize wall polysaccharides, assemble them into a strong fibrous network and regulate wall expansion during cell growth. Expand
Loosening of plant cell walls by expansins
TLDR
The recent explosion of gene sequences and expression data has given new hints of additional biological functions for expansin, which unlocks the network of wall polysaccharides, permitting turgor-driven cell enlargement. Expand
The expansin superfamily
TLDR
Experimental evidence suggests that expansins loosen cell walls via a nonenzymatic mechanism that induces slippage of cellulose microfibrils in the plant cell wall. Expand

TLDR
Experimental results indicate that cell wall enlargement may be regulated at many levels. Expand
Two endogenous proteins that induce cell wall extension in plants.
TLDR
It is found that a crude protein extract from the cell walls of growing cucumber seedlings possessed the ability to induce the extension of isolated cell walls and these proteins appear to mediate "acid growth" responses of isolated walls and may catalyze plant cell wall extension by a novel biochemical mechanism.

TLDR
A summary model for wall extension is presented, in which expansin is a primary agent of wall extension, whereas endoglucanases, xyloglucaan endotransglycosylase, and other enzymes that alter wall structure act secondarily to modulate expansin action. Expand
Crystal structure and activity of Bacillus subtilis YoaJ (EXLX1), a bacterial expansin that promotes root colonization
TLDR
The crystal structure of a secreted protein, EXLX1, encoded by the yoaJ gene of Bacillus subtilis, is solved and the discovery of a bacterial homolog opens the door for detailed structural studies of expansin function. Expand

TLDR
A pH-dependent mechanism of wall loosening, known as acid growth, is characteristic of growing walls and is mediated by a group of unusual wall proteins called expansins, which appear to disrupt the noncovalent bonding of matrix hemicelluloses to the microfibril, thereby allowing the wall to yield to the mechanical forces generated by cell turgor. Expand
Group I allergens of grass pollen as cell wall-loosening agents.
TLDR
It is proposed that group I allergens facilitate invasion of the pollen tube into the maternal tissues by loosening the cell walls of the grass stigma and style. Expand
Altered expression of expansin modulates leaf growth and pedicel abscission in Arabidopsis thaliana.

  • 15 August 2000
TLDR
The concept that expansins function endogenously as cell-wall-loosening agents and indicate that expansin have versatile developmental roles that include control of organ size, morphology, and abscission are supported. Expand
