Nitric oxide participates in cold-inhibited Camellia sinensis pollen germination and tube growth partly via cGMP in vitro. [PDF]

open access: yesPLoS ONE, 2012
Nitric oxide (NO) plays essential roles in many biotic and abiotic stresses in plant development procedures, including pollen tube growth. Here, effects of NO on cold stress inhibited pollen germination and tube growth in Camellia sinensis were ...

A chemical screen identifies two novel small compounds that alter Arabidopsis thaliana pollen tube growth

open access: yesBMC Plant Biology, 2019
Background During sexual reproduction, pollen grains land on the stigma, rehydrate and produce pollen tubes that grow through the female transmitting-tract tissue allowing the delivery of the two sperm cells to the ovule and the production of healthy ...

Low Concentration of Aluminum-Stimulated Pollen Tube Growth of Apples (Malus domestica)

open access: yesPlants, 2022
Aluminum (Al) is an important element in soil constitution. Previous studies have shown that high concentration of Al affects the normal growth of crops, resulting in crop yield reduction and inferior quality.

Arabidopsis LIM proteins PLIM2a and PLIM2b regulate actin configuration during pollen tube growth

open access: yesBiologia Plantarum, 2013
The pollen tube grows rapidly, exclusively at its tip, to deliver its sperm for fertilization. The polarized tip growth of pollen tubes is dependent on the highly dynamic actin cytoskeleton. Plant LIM proteins (named after initials of containing proteins

Pollen biology and hormesis: Pollen germination and pollen tube elongation

open access: yesScience of The Total Environment, 2021
This paper evaluated the occurrence of hormetic dose responses in pollen reported over the past eight decades. Hormetic doses responses were induced by a wide range of chemical and physical agents in 34 plant species for pollen germination and pollen tube growth/elongation.

PLC-Mediated Signaling Pathway in Pollen Tubes Regulates the Gametophytic Self-incompatibility of Pyrus Species

open access: yesFrontiers in Plant Science, 2017
Among the Rosaceae species, the gametophytic self-incompatibility (GSI) is controlled by a single multi-allelic S locus, which is composed of the pistil-S and pollen-S genes.

The Arabidopsis thaliana Class II Formin FH13 Modulates Pollen Tube Growth

open access: yesFrontiers 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.

Heteranthery in Clarkia: pollen performance of dimorphic anthers contradicts expectations. [PDF]

open access: yes, 2019
Premise of the studyWild plant species that require the services of pollen-feeding insects for reliable pollination may evolve features that attract and reward their mutualistic partners.

Overexpression of the Tomato Pollen Receptor Kinase LePRK1 Rewires Pollen Tube Growth to a Blebbing Mode [PDF]

open access: yes, 2014
The tubular growth of a pollen tube cell is crucial for the sexual reproduction of flowering plants. LePRK1 is a pollen-specific and plasma membrane–localized receptor-like kinase from tomato (Solanum lycopersicum). LePRK1 interacts with another receptor,

Mechanistic insights from a quantitative analysis of pollen tube guidance

open access: yesBMC Plant Biology, 2010
Background Plant biologists have long speculated about the mechanisms that guide pollen tubes to ovules. Although there is now evidence that ovules emit a diffusible attractant, little is known about how this attractant mediates interactions between the ...
