Tag: Cell Walls

By Daniel Cosgrove The primary wall of a growing cell is a versatile, subtle, and dynamic structure, with unique properties and functions in the life of the plant (Burton et al., 2010). When a cell grows, its wall stretches irreversibly as the cell enlarges in volume. Cells can start and stop this…

To regulate the addition of cell wall components as cells expand and to control changes in cell wall composition as cells differentiate, there must be a feedback system that senses the state of the cell wall and transmits this information. The mechanisms underlying cell wall-intracellular signaling remain…

Plant cell walls have recently been revealed as an essential factor of plant environment monitoring system, much more than just a passive defensive barrier as previously thought. In a recent work, Bacete et al. have reviewed how changes to plant cell wall integrity affect disease resistance. More specifically,…

Plants can reach impressive heights, thanks to the mechanical stability provided by the cell walls. The required strength is ensured by coordination of cell wall deposition and cell expansion. Plant-specific calpain (DEK1) regulates axial stem growth, as lines overexpressing the calpain domain develop…

A hallmark of xylem development is the deposition of secondary cell wall material in specific patterns (reviewed in Patrick et al, 2007). These cell wall deposits structurally reinforce the xylem to withstand negative pressure during water transport and differ in different xylem cell types. While it…
