Cell-Type-Specific Heat-Induced Changes in the Proteomes of Pollen Mother Cells and Microspores Provide New Insights into Tomato Pollen Production Under Elevated Temperature

Proteomes
Background: Tomatoes are self-pollinating plants, and successful fruit set depends on the production of functional pollen within the same flower. Our previous studies have shown that the ‘Black Vernissage’ tomato variety exhibits greater resilience to ...

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

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.

The pollen tube: a soft shell with a hard core

, 2013
Plant cell expansion is controlled by a fine-tuned balance between intracellular turgor pressure, cell wall loosening and cell wall biosynthesis. To understand these processes, it is important to gain in-depth knowledge of cell wall mechanics.

Links between morphology and function of the pollen wall: an experimental approach

, 2016
International audienceThe wall of pollen grains exhibits morphological variation in many features including apertures, ornamentation and thickness, but the function of these characters remains to be clarified. It has been suggested that they are involved

Cell wall reformation by pollen tube protoplasts of olive (Olea europaea L.): structural comparison with the pollen tube wall

, 2002
Mature pollen grains of olive (Olea europaea L.) were germinated in vitro in Brewbaker and Kwack medium, and emerging pollen tubes were then enzymatically digested in the presence of high osmoticum.

The growth of the pollen tube wall in Oenothera organensis.

, 1975
The growth of the pollen tube wall of Oenothera is effected by the expulsion of fibrillar material from the cytoplasm into the developing wall. This material may also be seen in the cytoplasm, contained in membrane-bound vesicles. It is not clear how the

Vitis vinifera - a chemotaxonomic approach: Pollen wall proteins

, 2015
The electrophoretic pattern of the pollen wall proteins from clones of cv. Nebbiolo grown in different areas show a geographical clustering.

Pollen Wall Structure, A New Interpretation

, 1986
A new preparative procedure using potassium permanganate has enabled previously undescribed structures on the surface and in the walls of pollen grains to be visualised.

Developmental biology of the pollen wall in Arabidopsis

, 1998
Thesis (PhD) -- University of Melbourne, Faculty of Science, 1999Includes bibliographical references.By selectively removing individual genes in mutant plants, the processes involved in pollen development can be dissected and characterised.
