Plant-type cell wall loosening
WebThe plant cell wall has high tensile strength and must be loosened to enable the cell to grow (enlarge irreversibly). [19] Within the cell wall, this expansion of surface area involves slippage or movement of cellulose microfibrils, which normally is coupled to simultaneous uptake of water. WebSep 15, 2002 · We analyzed the growth rate and the cell wall properties of coleoptiles of rice seedlings grown at 23.6 degrees C for 68.5, 91.5 and 136 h during the Space Shuttle STS-95 mission. In space, elongation growth of coleoptiles was stimulated and the cell wall extensibility increased.

However, monocot counterparts that function in kernel endosperm development have yet to be discovered. Here, we performed a multi-omic analysis to explore the function of GPI …
Webclass of cell wall proteins, "expansins," which may represent the key players in the elusive wall-loosening mechanism (7). At the very least they account for one type of wall extension. Expansins have been shown to increase the extensibility of isolated cell walls without causing time-dependent weakening (8). Expan-sins are activated at acid pH ... WebApr 1, 2009 · It is suggested that RhEXPA1 and RhXTH1 are the major paralogs involved in expansion growth of rose petals, which are probably involved in cell-wall loosening in plants. As flower opening involves the expansion of petal cells, the mechanisms of expansion growth were investigated in Rosa hybrida L. ‘FEbesa’ (syn. ‘Pretty Woman’) petals. Petal …
Web4.1 Cell biology of cell expansion—the role of expansins. Cell expansion requires the synthesis of new cell wall material and controlled loosening of the wall to allow it to stretch and increase in area. Cell-wall-associated proteins of the so-called expansin family are key components in this process. Expansins increase wall extensibility ...
