Comparative profiling examines roles of DNA regulatory sequences and accessible chromatin during cold stress response in grasses
Research, The Plant Cell, The Plant Cell: In BriefPhysical access to regulatory DNA, including cis-regulatory sequences found within proximal promoters and distal enhancer elements, is a vital property of chromatin. In turn, their access is determined by nucleosome occupancy and post-translational modification of histone proteins. A continuum of chromatin…

Close Encounters of the ARF Kind: Proximity-based ARF1 GTPase Activity Regulates Vesicle Trafficking
Research, The Plant Cell, The Plant Cell: In BriefADP-RIBOSYLATION FACTOR (ARF) proteins play essential roles in vesicle trafficking by regulating the formation of membrane vesicles that move cargo throughout the cell. Their activity is controlled by specific guanine exchange factors (ARF-GEFs) that activate ARFs by catalyzing a GDP to GTP exchange…

FRA1 Kinesin Prevents Cell Wall Deposition from Going Off the Rails
Research, The Plant Cell, The Plant Cell: In BriefCellulose, hemicellulose, and pectin are the brick and mortar of the plant kingdom, and how they are laid has substantial impacts on plant morphology. Plant cell shape is dictated by the interplay between turgor pressure and heterogeneity in cell wall composition, whereby localized cell wall loosening…
