🌱🧩 How do plant cells get their shape? 🧪

Check out the new #open-access #review exploring the mechanochemical duet between auxin & the cell wall in shaping diverse plant cell types from @srobertgroup.bsky.social's Lab.

🔗 doi.org/10.1111/ppl....

#PlantBiology #CellShape #Auxin #Biomechanics

Epidermal cells acquire different cell shapes to enable their functions and maintain tissue integrity in plants. Meristematic cells differentiate and expand into diverse mature cell types, including jigsaw puzzle-shaped pavement cells (a), round stomatal guard cells (b), elongated epidermal cells in hypocotyls and the apical hook (c), and root epidermal cells with root hairs (d). The spatial distribution and arrangement of cell wall polysaccharides, such as cellulose microfibrils, xyloglucans, and pectins (e.g., homogalacturonan represent as HG), and the abundance of methylester groups on these components in differentiating cells regulate anisotropy during cell growth, enabling the acquisition of specific cell shapes. In addition, proteins like KATANIN and CLASP reorient dynamically the cortical microtubules. These cortical microtubules rearrangement is in response to mechanical cues, either self-generated (as in b, c) or from neighboring cells (a, c), leading to the resulting cell shape.

Auxin controls cell expansion by regulating cell wall biosynthesis and cell remodeling. Auxin promotes cell expansion by acidifying the cell wall and activating wall synthesis and loosening enzymes. Auxin efflux (PINs) and influx (AUX1) transporters establish concentration gradients in growing tissue. Auxin enters cells via influx transporters and activates the TRANSPORT INHIBITOR RESPONSE 1/AUXIN SIGNALING F-BOX PROTEINS-AUXIN/INDOLE ACETIC ACID (TIR1/AFB-Aux/IAA) nuclear signaling cascade, which regulates auxin-responsive genes, including AUXIN RESPONSE FACTORs (ARFs) and SMALL AUXIN UP RNAs (SAURs). Auxin activates the H+-ATPase proton pump through TRANSMEMBRANE KINASE 1 (TMK1), acidifying the cell wall and triggering loosening enzymes including PECTIN METHYLESTERASEs (PMEs), EXPANSINs, and XYLOGLUCAN:XYLOGLUCOSYL TRANSFERASEs (EXTs). Cellulose microfibrils are synthesized by the plasma membrane-bound cellulose synthase complex (CSC), with cortical microtubules guiding the exocytosis of this complex toward expanding cell edges. Auxin coordinates the reorientation of cortical microtubules and actin filaments to regulate the trafficking of cell wall polysaccharides to ensure proper cell wall expansion and specific cell shape acquisition.
