Penetration of the stigma and style elicits a novel transcriptome in pollen tubes, pointing to genes critical for growth in a pistil. [PDF]
PLoS Genetics, 2009 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 medium, their trajectory is random and their growth rates are slower compared ...

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

The effect of temperature on pollen germination and pollen tube growth of pear cultivars [PDF]
Journal of Agricultural Sciences (Belgrade), 2016 The effect of three different temperatures (8, 16 and 24°C) on pollen germination and length of pollen tube in vitro was investigated in four pear cultivars (‘Butirra Precoce Morettini’, ‘Williams’, ‘Conference’ and ‘Abate Fetel’).

The Arabidopsis thaliana Class II Formin FH13 Modulates Pollen Tube Growth
Frontiers in Plant Science, 2021 Formins are a large, evolutionarily conserved family of actin-nucleating proteins with additional roles in regulating microfilament, microtubule, and membrane dynamics.

Plasma membrane H+-ATPases sustain pollen tube growth and fertilization
Nature Communications, 2020 Pollen tubes are highly polarized tip-growing cells that depend on cytosolic pH gradients for signaling and growth. Autoinhibited plasma membrane proton (H+) ATPases (AHAs) have been proposed to energize pollen tube growth and underlie cell polarity ...

Pollen Tube and Plant Reproduction [PDF]
International Journal of Molecular Sciences, 2019 The pollen tube was a fundamental step forward in the evolution of terrestrial plants; in fact, it allowed plants to liberate themselves from water demand during reproduction [...]

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 ...

Pollen Germination and Pollen Tube Growth in Gymnosperms [PDF]
Plants, 2021 Pollen germination and pollen tube growth are common to all seed plants, but these processes first developed in gymnosperms and still serve for their successful sexual reproduction. The main body of data on the reproductive physiology, however, was obtained on flowering plants, and one should be careful to extrapolate the discovered patterns to ...
