Description
Jiang Li and co-authors trace how a plant protein ferries wall material in growing pollen tubes in this 2024 study. Pollen tubes grow only at the tip, racing to deliver sperm for double fertilization. Actin strands guide the vesicles that carry wall parts to that tip.
A formin protein, AtFH5, sits on those vesicles and builds actin. Screening its partners turned up many wall-related proteins. One, AGP23, appeared most often and binds the formin directly. The team shows the formin recruits and hauls that cargo. Without the pairing, tip growth falters. The work fills a gap in how plants build new wall at a moving front.
