Cell Wall Composition, Biosynthesis and Remodeling during Pollen Tube Growth

open access: yesPlants, 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 ...

Sequential Deposition and Remodeling of Cell Wall Polymers During Tomato Pollen Development [PDF]

open access: yesFrontiers in Plant Science, 2021
The cell wall of a mature pollen grain is a highly specialized, multilayered structure. The outer, sporopollenin-based exine provides protection and support to the pollen grain, while the inner intine, composed primarily of cellulose, is important for ...

Rice GA3ox1 modulates pollen starch granule accumulation and pollen wall development. [PDF]

open access: yesPLoS ONE, 2023
The rice GA biosynthetic gene OsGA3ox1 has been proposed to regulate pollen development through the gametophytic manner, but cellular characterization of its mutant pollen is lacking.

Less and shrunken pollen 1 (LSP1) encodes a member of the ABC transporter family required for pollen wall development in rice (Oryza sativa L.)

open access: yesCrop Journal, 2020
Pollen fertility is an agronomic trait that strongly influences rice yield. Recent studies have revealed that the development of the pollen wall is required for pollen fertility and is regulated by several genes. However, the mechanisms underlying pollen

Comparative transcriptome analysis and ChIP-sequencing reveals stage-specific gene expression and regulation profiles associated with pollen wall formation in Brassica rapa [PDF]

open access: yesBMC Genomics, 2019
Background Genic male sterility (GMS) line is an important approach to utilize heterosis in Brassica rapa, one of the most widely cultivated vegetable crops in Northeast Asia. However, the molecular genetic mechanisms of GMS remain to be largely unknown.

Analysis of the Spatiotemporal Digestion Characteristics of Pine Pollen Processed by Different Methods in Middle-Aged Adults Using an In Vitro Digestion Model System [PDF]

open access: yesFoods
This study utilized a proprietary dynamic biomimetic digestion reactor to compare the differential behaviors of broken-wall pine pollen (PB), whole-wall pine pollen (WPB), and pine pollen wall extract (T) during simulated gastrointestinal digestion and ...

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 ...

2, 6-Dichlorobenzonitrile causes multiple effects on pollen tube growth beyond altering cellulose synthesis in Pinus bungeana Zucc. [PDF]

open access: yesPLoS ONE, 2013
Cellulose is an important component of cell wall, yet its location and function in pollen tubes remain speculative. In this paper, we studied the role of cellulose synthesis in pollen tube elongation in Pinus bungeana Zucc.

Maintenance of Methyl-Esterified Pectin Level in Pollen Mother-Cell Stages Is Required for Microspore Development

open access: yesPlants, 2023
Pectin modification and degradation are vital for plant development, although the underlying mechanisms are still not well understood. Furthermore, reports on the function of pectin in early pollen development are limited.
