Boron toxicity causes multiple effects on Malus domestica pollen tube growth
Frontiers in Plant Science, 2016 Boron is an essential micronutrient for plants. However, boron is also toxic to cells at high concentrations, although the mechanism of this stress is not known.

RALF signaling pathway activates MLO calcium channels to maintain pollen tube integrity
Cell Research, 2023 Pollen tube tip growth requires intricate Ca^2+ signaling. Recent studies have also identified rapid alkalization factor (RALF)-family peptides and their receptors as critical components for pollen tube tip growth and integrity.

A receptor-channel trio conducts Ca2+ signaling for pollen tube reception
Nature, 2022 Precise signalling between pollen tubes and synergid cells in the ovule initiates fertilization in flowering plants1. Contact of the pollen tube with the ovule triggers calcium spiking in the synergids2,3 that induces pollen tube rupture and sperm ...

The Arabidopsis GPI-anchored protein COBL11 is necessary for regulating pollen tube integrity
Cell Reports, 2023 Summary: Pollen tube integrity is required for achieving double fertilization in angiosperms. The rapid alkalinization factor4/19-ANXUR1/2-Buddha’s paper seal 1/2 (RALF4/19-ANX1/2-BUPS1/2)-complex-mediated signaling pathway is critical to maintain pollen

Durotropic Growth of Pollen Tubes [PDF]
Plant Physiology, 2020 To reach the female gametophyte, growing pollen tubes must penetrate different tissues within the pistil, the female reproductive organ of a flower. Past research has identified various chemotropic cues that guide pollen tubes through the transmitting tract of the pistil, which represents the longest segment of its growth path.

ROS in the Male–Female Interactions During Pollination: Function and Regulation
Frontiers in Plant Science, 2020 The male–female interactions in pollination mediate pollen hydration and germination, pollen tube growth and fertilization. Reactive oxygen species (ROS) derived from both male and female tissues play regulatory roles for the communication between the ...
