Microtubule-based perception of mechanical conflicts controls plant organ morphogenesis (Sci. Adv.)
Morphogenesis is a critical process in plants and animals that allows a cell, tissue, or organism to reach its final shape. In Arabidopsis thaliana, the formation of lateral root primordia (LRP) is an excellent example of organ morphogenesis that involves cell remodeling throughout differential growth…

Review: The mechanical feedback theory of leaf lamina formation ($) (Trends Plant Sci.)
The contribution of microtubule orientation to the direction of cell expansion is familiar to most; when microtubules wrap around the middle of a cell like a belt, the cell expands in the perpendicular direction to become longer. Recent studies have extended this idea and proposed that the mechanical…

Opposing, polarity-driven nuclear migrations underpin asymmetric divisions in stomatal patterning (Curr. Biol.)
Asymmetric cell divisions (ACDs) are often used by organisms to generate different cell sizes, each adopting a different cell fate. In plants, stomatal development provides an example of an ACD-derived patterning mechanism. Several proteins are known to be implicated in ACDs, like BREAKING OF ASYMMETRY…

Follow that Protein: SNAP-tagging Permits High-resolution Protein Localization
Protein analysis relies heavily on the production of ‘tagged’ proteins, i.e. recombinant proteins that contain both a functional peptide sequence and a peptide or chemical label (the ‘tag’). Common tags include fluorescent proteins (FPs), which make tagged proteins easier to detect, as well as…

Roles for this ROP GTPase in subcellular and tissue-level patterning (Plant Cell)
Rho-of-plants (ROP) proteins are master regulators of cell polarity within plants and influence cell wall deposition, tissue development, and several signaling processes. However, they are quite difficult to study: attempts to form a fluorescent ROP fusion protein have proven elusive, and there are multiple…
