Geometric and mechanical guidance: Role of stigmatic epidermis in early pollen tube pathfinding in arabidopsis. [PDF]

PLoS Computational Biology
In Arabidopsis thaliana, successful fertilisation relies on the precise guidance of the pollen tube as it navigates through the female tissues to deliver sperm cells to ovules.

Pollen-expressed RLCKs control pollen tube burst. [PDF]

Plant Commun
In angiosperms, the pollen tube enters the receptive synergid cell, where it ruptures to release its cytoplasm along with two sperm cells. This interaction is complex, and the exact signal transducers that trigger the bursting of pollen tubes are not well understood.

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

Molecular 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.

Boron toxicity causes multiple effects on Malus domestica pollen tube growth

Frontiers in Plant Science, 2016
Boron is an essential micronutrient for plants. However, boron is also toxic to cells at high concentrations, although the mechanism of this stress is not known.

RALF signaling pathway activates MLO calcium channels to maintain pollen tube integrity

Cell Research, 2023
Pollen tube tip growth requires intricate Ca^2+ signaling. Recent studies have also identified rapid alkalization factor (RALF)-family peptides and their receptors as critical components for pollen tube tip growth and integrity.

Identification and functional analysis of arabinogalactan protein expressed in pear pollen tubes

Journal of Integrative Agriculture, 2023
Arabinogalactan proteins (AGPs) are widely distributed in the plant kingdom and play a vital role during the process of plant sexual reproduction. In this study, we performed a comprehensive identification of the PbrAGPs expressed in pear pollen and ...

Male fertility in Arabidopsis requires active DNA demethylation of genes that control pollen tube function

Nature Communications, 2021
Active DNA demethylation is required for sexual reproduction in plants but the molecular determinants underlying this epigenetic control are not known.

Membrane receptor-mediated mechano-transduction maintains cell integrity during pollen tube growth within the pistil.

Developmental Cell, 2021
Invasive or penetrative growth is critical for developmental and reproductive processes (e.g., pollen tube penetration of pistils) and disease progression (e.g., cancer metastasis and fungal hyphae invasion).

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.
