This study identifies PP2A phosphatase as a potential dephosphorylating enzyme for TRAPPII subunit TRS120 in Arabidopsis, linking kinase-phosphatase balance to membrane trafficking.

The paper develops a triple fluorescent marker for live imaging of plant cell morphogenesis, enabling high-resolution visualization of cell membrane, nucleus, and microtubule dynamics in multiple plant organs.

The paper identifies CDKB1 and CYCB3;1 as regulators of spindle architecture in Arabidopsis, showing their role in modulating the augmin pathway through phosphorylation of EDE1.

The paper quantitatively analyzes spur morphogenesis in Staphisagria picta, revealing early cell proliferation followed by anisotropic expansion, and introduces a 3D analysis pipeline for plant tissues.

The paper analyzes variability in cell division patterns in Arabidopsis thaliana embryos using 3D imaging and modeling, revealing that variability is constrained by geometric rules.
