The PP2A phosphatase associates with the Arabidopsis TRAPPII tethering complex and dephosphorylates a TRAPPII-derived phosphopeptide in vitro

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

A triple fluorescent marker for live imaging of plant cell morphogenesis

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.

Actin Counters Geometry to Guide Plant Cell Division

The paper shows actin cytoskeleton integrates spatial information to guide cell division orientation in Arabidopsis root epidermis, deviating from geometric rules.

Semi-automatic quantification of 3D Histone H3 phosphorylation signals during cell division in Arabidopsis root meristems

The paper develops a semi-automated 3D image analysis pipeline to quantify H3S10 phosphorylation dynamics during mitosis in Arabidopsis root cells, revealing small differences in phosphorylation levels between treated cells and mutants.

The cell cycle controls spindle architecture in Arabidopsis by modulating the augmin pathway

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.
