Multicellular and socially aggregating prokaryotes contain previously undescribed, chaperone-based systems predicted to mediate defensive biological conflicts, several components of which are thematically similar antecedents of eukaryotic apoptosis pathways.

The formation of stomatal 'helper cells' (=subsidiary cells) in grasses requires two opposing polarity domains with diverse roles in establishing division asymmetry.

Implementation and characterisation of plasma-focused ion beams for volumetric imaging of cryogenically preserved cells and tissues for ultrastructural examination in their native state.

Analysis of the Arabidopsis V-ATPase reveals convergent evolution of differential targeting as well as redundancy of the endosomal and vacuolar isoforms during vegetative development.

Temperature-dependent fasciation mutants of Arabidopsis unexpectedly connect mitochondrial RNA processing to the control of cell proliferation during lateral root morphogenesis via electron transport chain activity and reactive oxygen species production.

Stromules induced during plant innate immunity dynamically interact and use the cytoskeleton to form and to direct the movement of chloroplasts.
