Unusual behavior of growing pollen tubes in the ovary of plum culture (Prunus domestica L.) [PDF]

open access: yesArchives of Biological Sciences, 2010
Unusual behavior of growing pollen tubes in different combinations of pollination was observed in the ovary of the plum (Prunus domestica L.) cv 'Čačanska Lepotica'. It primarily refers to several issues, i.e.

How pollen tubes fight for food: the impact of sucrose carriers and invertases of Arabidopsis thaliana on pollen development and pollen tube growth [PDF]

open access: yesFrontiers in Plant Science, 2023
Pollen tubes of higher plants grow very rapidly until they reach the ovules to fertilize the female gametes. This growth process is energy demanding, however, the nutrition strategies of pollen are largely unexplored.

LINC-complex mediated positioning of the vegetative nucleus is involved in calcium and ROS signaling in Arabidopsis pollen tubes [PDF]

open access: yesNucleus, 2020
Nuclear movement and positioning play a role in developmental processes throughout life. Nuclear movement and positioning are mediated primarily by linker of nucleoskeleton and cytoskeleton (LINC) complexes.

Nanoporous silica gel can compete with the flower stigma in germinating and attracting pollen tubes [PDF]

open access: yesFrontiers in Plant Science, 2022
To find nanoporous substrates with hydrodynamic properties useful for pollen hydration and germination, we used the glassy Silica gel and Vycor scales and pollen with different morphological and physiological traits, that of Crocus vernus, and that of ...

Microtubules play a role in trafficking prevacuolar compartments to vacuoles in tobacco pollen tubes [PDF]

open access: yesOpen Biology, 2018
Fine regulation of exocytosis and endocytosis plays a basic role in pollen tube growth. Excess plasma membrane secreted during pollen tube elongation is known to be retrieved by endocytosis and partially reused in secretory pathways through the Golgi ...

Transcriptome profiling of tobacco (Nicotiana tabacum) pollen and pollen tubes [PDF]

open access: yesBMC Genomics, 2017
Background Pollen tube growth is essential for plant reproduction and represents a widely employed model to investigate polarized cell expansion, a process important for plant morphogenesis and development.

A Plant-Derived Antifungal Agent, Poacic Acid, Inhibits Germination and Tube Growth of Lily Pollen [PDF]

open access: yesPlants
Poacic acid is a novel natural antifungal agent. It inhibits the growth of fungal cells, including budding yeast Saccharomyces cerevisiae, by inhibiting the synthesis of β-1,3-glucan, which is a major component of the fungal cell wall.

Possible molecular mechanisms of persistent pollen tube growth without de novo transcription

open access: yesFrontiers 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 ...

Penetration of the stigma and style elicits a novel transcriptome in pollen tubes, pointing to genes critical for growth in a pistil. [PDF]

open access: yesPLoS 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 ...

Pollen tube tip growth [PDF]

open access: yesNew 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.
