The paper shows actin cytoskeleton integrates spatial information to guide cell division orientation in Arabidopsis root epidermis, deviating from geometric rules.

ROOT-ExM achieves super-resolution expansion microscopy in plants, enabling isotropic expansion and nanoscale visualization of cellular structures in Arabidopsis thaliana.

This study identifies the ERGIC in Arabidopsis as a dynamic, Golgi-independent tubular network that generates stable cisternae-like Golgi structures through sphingolipid acyl-chain length regulation.

The paper shows the ER stabilizes plasmodesmata during incomplete cytokinesis in plants by preventing fenestrae fusion and forming communication bridges between daughter cells.

The paper shows plasmodesmata function as ER-PM tubular membrane contact sites that regulate intercellular molecular exchange in plants through PI4P and MCTP proteins.
