Pollen tubes extend rapidly via tip growth. This process depends on a dynamic actin
cytoskeleton, which has been implicated in controlling organelle movements, cytoplasmic …

Highlights•Microfilaments (MFs) play a crucial role in pollen tube tip growth.•MFs
organization and dynamics are precisely controlled.•Microtubules organize into two different …

The actin cytoskeleton is one of the targets of the pH gradient in tip-growing cells, but how
cytosolic pH regulates the actin cytoskeleton remains largely unknown. We here …

Pollen tubes rapidly elongate, penetrate, and navigate through multiple female tissues to
reach ovules for sperm delivery by utilizing a specialized form of polar growth known as tip …

In plant cells, calcium (Ca2+) serves as a versatile intracellular messenger, participating in
several fundamental and important biological processes. Recent studies have shown that …

Cotton (Gossypium hirsutum) fibres consist of single cells that grow in a highly polarized
manner, assumed to be controlled by the cytoskeleton,–. However, how the cytoskeletal …

A population of dynamic apical actin filaments is required for rapid polarized pollen tube
growth. However, the cellular mechanisms driving their assembly remain incompletely …

Polarized tip growth is a fundamental cellular process in many eukaryotes. In this study, we
examined the dynamic restructuring of the actin cytoskeleton and its relationship to vesicle …
