An extracellular transglutaminase is required for apple pollen tube growth [PDF]

open access: yes, 2010
An extracellular form of the calcium-dependent protein-crosslinking enzyme TGase (transglutaminase) was demonstrated to be involved in the apical growth of Malus domestica pollen tube.

Nitric Oxide Participates in Aluminum-Stress-Induced Pollen Tube Growth Inhibition in Tea (Camelliasinensis) by Regulating CsALMTs

open access: yesPlants, 2022
Nitric oxide (NO), as a signal molecule, is involved in the mediation of heavy-metal-stress-induced physiological responses in plants. In this study, we investigated the effect of NO on Camellia sinensis pollen tubes exposed to aluminum (Al) stress ...

The pollen receptor kinase LePRK2 mediates growth-promoting signals and positively regulates pollen germination and tube growth [PDF]

open access: yes, 2008
In flowering plants, the process of pollen germination and tube growth is required for successful fertilization. A pollen receptor kinase from tomato (Solanum lycopersicum), LePRK2, has been implicated in signaling during pollen germination and tube ...

Immunofluorescence Labeling of Pollen Tubes

open access: yesBio-Protocol, 2014
Pollen tube is regarded as an excellent single-cell model system in plant cell studies. This protocol describes the use of a rapid and reliable immunofluorescence labeling method for studying in situ localization of proteins in pollen tubes.

Effect of boron toxicity on pollen tube cell wall architecture and the relationship of cell wall components of Castanea mollissima Blume

open access: yesFrontiers in Plant Science, 2022
Boron (B) is essential to plant development. However, excessive B is toxic to plants. This research was performed to evaluate the effects of B toxicity on cell wall architecture of Chinese chestnut (Castanea mollissima Blume) pollen tubes with emphasis ...

How pollen tubes grow

open access: yesDevelopmental Biology, 2007
Sexual reproduction of flowering plants depends on delivery of the sperm to the egg, which occurs through a long, polarized projection of a pollen cell, called the pollen tube. The pollen tube grows exclusively at its tip, and this growth is distinguished by very fast rates and reaches extended lengths.

Kanamycin resistance during in vitro development of pollen from transgenic tomato plants [PDF]

open access: yes, 1987
Effects of kanamycin on pollen germination and tube growth of pollen from non-transformed plants and from transgenic tomato plants containing a chimaeric kanamycin resistance gene were determined. Germination of pollen was not affected by the addition of

Phosphatidic acid counteracts S-RNase signaling in pollen by stabilizing the actin cytoskeleton [PDF]

open access: yes, 2018
S-RNase is the female determinant of self-incompatibility (SI) in pear (Pyrus bretschneideri). After translocation to the pollen tube, S-RNase degrades rRNA and induces pollen tube death in an S-haplotype-specific manner. In this study, we found that the

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

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,

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.
