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…

Follow that Protein: SNAP-tagging Permits High-resolution Protein Localization

Protein analysis relies heavily on the production of ‘tagged’ proteins, i.e. recombinant proteins that contain both a functional peptide sequence and a peptide or chemical label (the ‘tag’). Common tags include fluorescent proteins (FPs), which make tagged proteins easier to detect, as well as…

Tracking the Courier: In Planta Imaging of NADH/NAD+ Ratios with a Genetically Encoded Biosensor

The movement of electrons between molecules and organelles via redox reactions is a cornerstone of cellular metabolism. Electron carriers such as nicotinamide adenine dinucleotide (NAD) and its phosphorylated form NADP mediate reduction or oxidation reactions via their own conversion between reduced…
