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.

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.

This paper introduces a plasma membrane staining method using FM4-64 to visualize living cell morphology in reproductive tissues of diverse plant species, enabling high-resolution imaging and analysis without transgenic lines.

This study shows that brassinosteroids (BRs) function as reproductive hormones in Arabidopsis, regulating gene expression in both male and female reproductive tissues during fertilization.
