Schematic diagram of TfANX- and TfRABA4D-mediated pollen tube integrity and tip growth in T. fournieri. (A) TfANX regulates pollen tube integrity in a ROS-independent way, leading to the leakage in developing pollen tubes, distinct from rupture for sperm cell release in the mature pollen tube. (B) TfRABA4D supports tip growth by coordinating pectin deposition, vesicle distribution, and ROS accumulation, preventing abnormal swelling at the tip.
