The RALF signaling pathway regulates cell wall integrity during pollen tube growth in maize

bioRxiv, 2023
Autocrine signaling pathways regulated by RAPID ALKALINIZATION FACTORs (RALFs) control cell wall integrity during pollen tube germination and growth in Arabidopsis.

Cell Wall Composition, Biosynthesis and Remodeling during Pollen Tube Growth

Plants, 2013
The pollen tube is a fast tip-growing cell carrying the two sperm cells to the ovule allowing the double fertilization process and seed setting. To succeed in this process, the spatial and temporal controls of pollen tube growth within the female organ ...

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.

Transcriptome analysis provides insight into the regulatory mechanisms underlying pollen germination recovery at normal high ambient temperature in wild banana (Musa itinerans)

Frontiers in Plant Science, 2023
IntroductionCultivated banana are polyploid, with low pollen fertility, and most cultivars are male sterile, which leads to difficulties in banana breeding research. The selection of male parent with excellent resistance and pollen fertility is therefore

Arabidopsis Novel Microgametophyte Defective Mutant 1 Is Required for Pollen Viability via Influencing Intine Development in Arabidopsis

Frontiers in Plant Science, 2022
The pollen intine layer is necessary for male fertility in flowering plants. However, the mechanisms behind the developmental regulation of intine formation still remain largely unknown.

Radioautographic visualization of incorporation of lipid precursors into anthers of Muscari comosum (L.) Mili.

Acta Societatis Botanicorum Poloniae, 2015
Incorporation of the following lipid precursors: DL-mevalonic acid-2 3H, 3H palmitic acid and acetic acid-3H sodium salt, into the anther cells of Muscari comosum (L.) Mili. has been investigated.

Dissecting the regulation of pollen tube growth by modelling the interplay of hydrodynamics, cell wall and ion dynamics

Frontiers in Plant Science, 2014
Hydrodynamics, cell wall and ion dynamics are all important properties that regulate pollen tube growth. Currently, the two main pollen tube growth models, the cell wall model and the hydrodynamic model do not appear to be reconcilable.

The ATP-binding cassette (ABC) transporter OsABCG3 is essential for pollen development in rice

Rice, 2018
Background The pollen wall, which protects male gametophyte against various stresses and facilitates pollination, is essential for successful reproduction in flowering plants.

Cytological and Proteomic Analysis of Ginkgo biloba Pollen Intine

Horticultural Plant Journal, 2020
The pollen intine plays important roles in pollen germination and tube growth, but related information in Ginkgo biloba remains unclear. We isolated and obtained de-exined pollen from G. biloba.
