HHS The Arabidopsis root allows dissection of different aspects of cell polarity in plants. In maize, before the SMC asymmetric division, the SCAR/WAVE regulatory complex first polarizes to the membrane adjacent to the guard mother cell (GMC) contact sites, where PAN2 polarizes subsequently. The TMK proteins are first induced by auxin to form large nanoclusters. 2004; Huang et al. Cell polarity refers to spatial differences in shape, structure, and function within a cell. Figure 1.. PIN distribution and polarization in…, Figure 1.. PIN distribution and polarization in the plant development, Figure 2.. 2011; Zhang et al. Some proteins escape vacuolar degradation from the endosomes by returning to the PM via the recycling pathways. zarsky@ueb.cas.cz In plants, exocytosis is a central mechanism of cell morphogenesis. Considering that GNOM functions as an ARF GEF, some ARF GTPases are the possible candidates participating in this process. 2009 Feb;12(1):42-8. doi: 10.1016/j.pbi.2008.09.009. Also, it was noted that the TGN as a membrane sorting platform in plant cells plays critical roles in the establishment of the PM polarity domains. 2019). The polarity axes are established at the stage of zygote, extending to the developing embryo, and they "vectorize" subsequent plant growth and development. Additionally, AtRabA4b was found to label a TGN compartment that is polarly distributed in the growing root hairs, where RabA4b promotes polarized secretion of cell wall components to support tip growth (Preuss et al. To establish cell polarity, the small GTPases, such as RAB and ARF, may regulate vesicular trafficking between intracellular compartments by recruiting coat protein complexes to the vesicle formation sites, organizing the cytoskeleton, and docking vesicles to the destination membranes (Nielsen et al. The delivery of either newly synthesized or recycled materials back to the PM is connected to the maintenance of protein homeostasis at the PM. The morphology of living organisms is organized in four dimensions and naturally includes symmetric and asymmetric structures. The polarization of ROPs was evident in a number of cell systems, for example, the pollen tube, root hair, and pavement cells (Craddock et al.
