Pollen Germination and Pollen Tube Growth in Gymnosperms. [PDF]

open access: yesPlants (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.

Mechanics and Hydraulics of Pollen Tube Growth. [PDF]

open access: yesNew Phytologist, 2021
All kingdoms of life have evolved tip-growing cells able to mine their environment or deliver cargo to remote targets. The basic cellular processes supporting these functions are understood with increasing details but the multiple interactions between ...

Pollen Tube Growth and Self-Compatibility in Almond [PDF]

open access: yesPlants, 2013
Although pollen tube growth has been an important criterion for self-compatibility evaluation in almond, there is not a clear-cut separation between positive and negative growth of pollen tubes in the different genotypes.

Editorial: Regulation of Pollen Tube Growth. [PDF]

open access: yesFront 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 ...

Self S-RNase reduces the expression of two pollen-specific COBRA genes to inhibit pollen tube growth in pear [PDF]

open access: yesMolecular Horticulture, 2023
Due to self-incompatibility (SI) prevents self-fertilization, natural or artificial cross-pollination has been conducted in many orchards to stabilize fruit yield.

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

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 ...

Rice UCL8, a plantacyanin gene targeted by miR408, regulates fertility by controlling pollen tube germination and growth

open access: yesRice, 2018
Background Pollen tube formation and growth are crucial steps that lead to seed production. Despite the importance of pollen tube growth, the molecular mechanisms implicated in its spatial and temporal control are not fully known. In this study, we found

WD40-domain protein GORI is an integrative scaffold that is required for pollen tube growth in rice [PDF]

open access: yesPlant 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,

Spermine Regulates Pollen Tube Growth by Modulating Ca2+-Dependent Actin Organization and Cell Wall Structure

open access: yesFrontiers in Plant Science, 2017
Proper growth of the pollen tube depends on an elaborate mechanism that integrates several molecular and cytological sub-processes and ensures a cell shape adapted to the transport of gametes.

Arabidopsis COG Complex Subunits COG3 and COG8 Modulate Golgi Morphology, Vesicle Trafficking Homeostasis and Are Essential for Pollen Tube Growth. [PDF]

open access: yesPLoS Genetics, 2016
Spatially and temporally regulated membrane trafficking events incorporate membrane and cell wall materials into the pollen tube apex and are believed to underlie the rapid pollen tube growth.
