Evidence for Two Distinct Stages in Secondary Cell Wall Formation of Xylem
Blog, Research, Research Blog, The Plant Cell, The Plant Cell: In BriefA 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…

Cell walls are complex mixtures of cellulose microfibrils, proteins and other materials. Their mechanical properties can be measured and modeled, but it is not always simple to translate these measurements to changes at the molecular level. Zhang et al. used atomic force microscopy to provide an unprecedented…
