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…

More Than Just a FAD(5): Unsaturated Fatty Acids in Chloroplasts Elicit Protective Autoimmunity

Arabidopsis (Arabidopsis thaliana) chloroplast-division mutants that have abnormally large chloroplasts have been around for quite some time, not only because they can be identified relatively easily through screening (Pyke & Leech 1991) and because their spectacular morphology sparks intrigue, but…
