The paper introduces Apical3DTip, a method for 3D and 4D analysis of Arabidopsis embryo initial cell morphology using elliptic cross-sections and coordinate normalization, enabling accurate geometric characterization without mesh reconstruction.

The paper develops a deformation gradient tensor model to describe the roll-spiral transformation in protein refractile bodies, linking macroscopic morphology with microscopic lattice deformation.

The paper shows that temporal changes in surface tension at the growing tip of Arabidopsis zygotes maintain cortical microtubule bands, which guide the formation of the preprophase band and ensure asymmetric cell division.

This study shows Ca2+ oscillations drive microtubule-band turnover and support tip growth in Arabidopsis zygotes through a feedback loop, distinct from actin-based tip growth mechanisms.

The paper shows that plastids in Arabidopsis zygote undergo two-step migration via F-actin and microtubules, leading to unequal inheritance during asymmetric division.

KymoTip is a tool for analyzing live imaging data of plant cell tip growth, enabling accurate quantification of cell dynamics and intracellular events despite fluctuations in position and shape.

The paper uses an agent-based simulation to study cortical microtubule band movement in Arabidopsis zygotes, identifying self-organization processes and the role of directional cues.

The paper develops a viscoelastic-plastic model to simulate tip growth in Arabidopsis zygotes and identifies non-dimensional parameters that maintain a hemisphere-like shape.

The paper shows that cell lineages in Arabidopsis sepal develop from size uniformization to enhancement of size variability during growth.
