Cortical microtubules act as a template to organize nano-scale patterning of exocytosis Targeting of exocytosis enables cellular morphogenesis, motility and polarized transport, yet relatively little is known about the targeting mechanisms in cellular systems. Here we show that the SEC/M...

Actin-mediated avoidance of tricellular junction influences global topology at the Arabidopsis shoot apical meristem The majority of newly formed cellular vertices are placed away from existing tricellular vertices during cell division at the shoot apical meristem in plants. Wang et al. here show that the actin cyto...

Spatiotemporally distinct responses to mechanical forces shape the developing seed of Arabidopsis | The EMBO Journal imageimageIn plants, organ and tissue growth is regulated by mechanical force-dependent rearrangement of cortical microtubules and resulting changes in cell wall material deposition. This study shows ...

Confined-microtubule assembly shapes three-dimensional cell wall structures in xylem vessels - Natur... In plant metaxylem, three-dimensional cell wall arches are formed over pit membranes. Here, the authors show that the microtubule-associated proteins, MAP70-5 and MAP70-1, confine microtubules within ...
