Pollen Germination and Pollen Tube Growth in Gymnosperms. [PDF]
Plants (Basel), 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 ...

Editorial: Regulation of Pollen Tube Growth. [PDF]
Front Plant Sci, 2021 In angiosperms, the pollen tube is a simple system composed of the vegetative cell and the two sperm cells which, nevertheless, accomplishes a very important process, essential for the life of flowering plants on Earth, i.e., sexual reproduction. In its simplicity, the pollen tube allowed plants to reproduce on land, even in the absence of water ...

WD40-domain protein GORI is an integrative scaffold that is required for pollen tube growth in rice [PDF]
Plant Signaling & Behavior, 2023 The pollen tube plays a critical role in angiosperm plants by delivering sperm gametes for double fertilization. Although the molecular mechanisms underlying pollen tube germination and growth are crucial to crop plants, they are poorly understood. Here,

Possible molecular mechanisms of persistent pollen tube growth without de novo transcription [PDF]
Frontiers in Plant Science, 2022 The vegetative cell nucleus proceeds ahead of a pair of sperm cells located beneath the pollen tube tip during germination. The tip-localized vegetative nucleus had been considered to play a pivotal role in the control of directional pollen tube growth ...

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.

Identification and functional analysis of arabinogalactan protein expressed in pear pollen tubes
Journal of Integrative Agriculture, 2023 Arabinogalactan proteins (AGPs) are widely distributed in the plant kingdom and play a vital role during the process of plant sexual reproduction. In this study, we performed a comprehensive identification of the PbrAGPs expressed in pear pollen and ...

New Phytologist, 1989 summaryThis review considers pollen tube growth with regard to current information on pollen tube cytoplasm, wall structure and calcium ion interactions with pollen tubes. Pollen tubes have a marked cytoplasmic Polarity with a number of distinct zones along the tube, each with a characteristic complement of cytoplasmic and nuclear structures.

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.
