Plant cells are surrounded by cell walls protecting them from a myriad of environmental
challenges. For successful habitat adaptation, extracellular cues are perceived at the cell …

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

Higher plants survive terrestrial water deficiency and fluctuation by arresting cellular
activities (dehydration) and resuscitating processes (rehydration). However, how plants …

In flowering plants, sperm are transported inside pollen tubes to the female gametophyte for
fertilization. The female gametophyte induces rupture of the penetrating pollen tube …

During sexual reproduction of flowering plants, pollen tube guidance by pistil tissue is critical
for the delivery of nonmotile sperm cells to female gametes. Multistep controls of pollen tube …

Pollen tubes extend through pistil tissues and are guided to ovules where they release
sperm for fertilization. Although pollen tubes can germinate and elongate in a synthetic …

The precise delivery of male to female gametes during reproduction in eukaryotes requires
complex signal exchanges and a flawless communication between male and female tissues …
