Nanoscale movements of cellulose microfibrils in primary cell walls ($)

/
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…

Roles for this ROP GTPase in subcellular and tissue-level patterning (Plant Cell)

Rho-of-plants (ROP) proteins are master regulators of cell polarity within plants and influence cell wall deposition, tissue development, and several signaling processes. However, they are quite difficult to study: attempts to form a fluorescent ROP fusion protein have proven elusive, and there are multiple…
