  Secondary cell walls support vascular plants and conduct water throughout the plant body, and are crucial resources for lignocellulosic feedstocks. Here the authors present convincing genetic and biochemical evidence that secondary cell wall synthesis, known already to be under complex transcriptional control, is also controlled post-transcriptionally by MUSASHI-like RNA-binding proteins. These important results point to a new mechanism for control of secondary cell wall synthesis, which will be interesting to cell biologists and biochemists studying and attempting to manipulate plant biomass.

  This is a valuable study of Arabidopsis shoot apical meristem maintenance and organ initiation, defining the expression, interactions and functions of four transcription factors (SHR, SCR, JKD, and SCL23) whose roles were initially described in the root apical meristem. The imaging, genetics and FRET-FLIM evidence supporting the claims of the authors is comprehensive, extensive, and solid, although similar mechanisms, protein interactions, and gene regulatory interactions were previously reported in the root. The work will be of interest and importance for plant developmental biologists.

  Plant intracellular ion channels are poorly understood. In this important manuscript, patch-clamp is used to define functional differences between two cation channels present in the vacuole of different plants. The authors find a calcium-biding site whose absence or presence modulate activation at lower voltages and is responsible for increased excitability in the vacuole of the faba bean plant. The experimental evidence presented is convincing and findings have practical implications for the field of plant electrophysiology and channel biophysics.
