MYB97, MYB101 and MYB120 function as male factors that control pollen tube-synergid interaction in Arabidopsis thaliana fertilization. [PDF]

PLoS Genetics, 2013
Pollen tube reception involves a pollen tube-synergid interaction that controls the discharge of sperm cells into the embryo sac during plant fertilization.

A Complex Journey: Cell Wall Remodeling, Interactions, and Integrity During Pollen Tube Growth

Frontiers in Plant Science, 2020
In flowering plants, pollen tubes undergo a journey that starts in the stigma and ends in the ovule with the delivery of the sperm cells to achieve double fertilization.

Structure and function of class III pistil-specific extensin-like protein in interspecific reproductive barriers

BMC Plant Biology, 2019
Background The transmitting tissue of the style is the pathway for pollen tube growth to the ovules and has components that function in recognizing and discriminating appropriate pollen genotypes. In Nicotiana tabacum, the class III pistil extensin-like (

Knockin’ on pollen’s door: live cell imaging of early polarization events in germinating Arabidopsis pollen

Frontiers in Plant Science, 2015
Pollen tubes are an excellent system for studying the cellular dynamics and complex signaling pathways that coordinate polarized tip growth. Although several signaling mechanisms acting in the tip-growing pollen tube have been described, our knowledge on

The effect of temperature on pollen germination and pollen tube growth of pear cultivars [PDF]

Journal of Agricultural Sciences (Belgrade), 2016
The effect of three different temperatures (8, 16 and 24°C) on pollen germination and length of pollen tube in vitro was investigated in four pear cultivars (‘Butirra Precoce Morettini’, ‘Williams’, ‘Conference’ and ‘Abate Fetel’).

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

, 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.

ROS in the Male–Female Interactions During Pollination: Function and Regulation

Frontiers in Plant Science, 2020
The male–female interactions in pollination mediate pollen hydration and germination, pollen tube growth and fertilization. Reactive oxygen species (ROS) derived from both male and female tissues play regulatory roles for the communication between the ...

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

, 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

The Tip-Localized Phosphatidylserine Established by Arabidopsis ALA3 Is Crucial for Rab GTPase-Mediated Vesicle Trafficking and Pollen Tube Growth

The Plant Cell, 2020
Arabidopsis ALA3 plays a key role in the inverted-cone distribution of phosphatidylserine at the pollen tube tip, and phosphatidylserine is crucial for the distribution and activity of certain Rab GTPases as well as pollen tube growth.
