Pollen Germination and Pollen Tube Growth
2001Pollen, the male gametophyte of higher plants, is a biological system playing a central role in sexual plant reproduction (Cresti et al., 1992). The understanding of the mechanisms controlling the various aspects of pollen tube development has a direct relevance to biotechnological applications since it represents a starting point to modify crop ...

Pollen tubes and the physical world
Trends in Plant Science, 2011The primary goal of our previous opinion paper (Winship, L.J. et al. (2010) Trends Plant Sci. 15, 363-369) [1] was to put two models for the control of pollen tube growth on the same theoretical and biophysical footing, and to then test both for consistency with basic principles and with experimental data.

POLLEN GERMINATION AND TUBE GROWTH
Annual Review of Plant Physiology and Plant Molecular Biology, 1997▪ Abstract Many aspects of Angiosperm pollen germination and tube growth are discussed including mechanisms of dehydration and rehydration, in vitro germination, pollen coat compounds, the dynamic involvement of cytoskeletal elements (actin, microtubules), calcium ion fluxes, extracellular matrix elements (stylar arabinogalactan proteins), and control

MARIS plays important roles in Arabidopsis pollen tube and root hair growth.
Journal of Integrative Plant Biology, 2016In flowering plants, male gametes are delivered to female gametes for double fertilization through pollen tubes. Therefore, pollen tube growth is crucial for double fertilization.

The mechanism and key molecules involved in pollen tube guidance.
Annual Review of Plant Biology, 2015During sexual reproduction of flowering plants, pollen tube guidance by pistil tissue is critical for the delivery of nonmotile sperm cells to female gametes.

Pollen Germination and Pollen-Tube Growth
1987Publisher Summary Pollen germination and pollen-tube growth events when viewed either in culture or in the style are considered as biochemically, physiologically, and structurally complex. The various processes involved are each independent in some measure, but still all are interactive—namely, the successful attainment of the delivery of two male ...

1973
The pollen tube of flowering plants may grow through as much as 50 cm of the stylar tissue, enter the micropyle of an ovule and then discharge from its tip two non-motile sperm cells in the immediate vicinity of an unfertilized egg. This review is concerned with the factors that direct the pollen tube to the egg.

Pollen Germination and Pollen Tube Growth in Vitro
1992Pollen germination and pollen tube growth are prerequisites for fertilization and seed development. Because of the involvement of the pistillate tissue in nature, physiologic and biochemical investigations on pollen germination and pollen tube growth in vivo are rather difficult. In vitro germination techniques have therefore been used extensively on a
