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…

Tempting Fate: A Guanylate-Binding Protein Maintains Tomato Fruit Cell Differentiation

Tissues are composed of specialized cell types. As a cell matures, it acquires the characteristics associated with a specific identity, or fate. This process is called cell differentiation and is crucial for proper organ development. However, after a differentiation program is initiated, the mechanisms…
