Modeling of Pollen Tube Growth
CD BioSciences is committed to providing our clients with modeling services for pollen tube growth in order to obtain important information on the expansion pressure, cellular mechanical properties and non-linear dynamics of pollen tube growth. Our dedicated research team will provide you with the best modeling solutions and real-time technical guidance throughout the process.
Background
Pollen tube growth is a process of polar cell growth that relies on two main systems: a mechanical system that deforms the cell wall, and a signaling system that brings vesicles to the site of growth. This process involves membrane growth and cell wall expansion confined to the apical region of the pollen tube by the fusion of vesicles containing cell membrane and cell wall material. By directing the apical growth region, the pollen tube can transmit sperm for fertilization through the female tissue of the plant. Studying the dynamic behavior of pollen tubes during growth can provide the basis for a deeper understanding of more complex cells that exhibit similar growth behavior.
The cell wall, hydrodynamics and ion dynamics are all important properties that regulate the growth of pollen tubes. A number of pollen growth models have been proposed to address the complex nature of apical growth. Most models attempt to explain polar growth by capturing different cellular processes in the form of differential equations. These equations are constructed based on what is known about the function of each variable (pressure, protein, cellular, ion, composition, etc.) and how these variables interact with each other, providing useful information for analyzing the dynamic processes of pollen tube growth.

Our Services
To gain insight into pollen tube growth, we are committed to providing our clients with modeling services for pollen tube growth. The services we provide include but are not limited to:
- Osmotic model of growing pollen tubes
We help our clients to develop quantitative physiological models, including the entry of water by osmosis, the incorporation of cell wall material and the diffusion of this material in the form of thin films at the tip. We determine the parameters of this model using techniques such as optical, confocal and electron microscopy. The modeling can provide important information to explain the role of turgor pressure and the constancy it observes during oscillations.
- Hydrodynamic model of growing pollen tubes
We help our clients build hydrodynamic models to investigate the mechanisms driving random and oscillatory growth and oscillations in cell signaling and ion flux during pollen tube growth.
- An integrated model of pollen tube growth
We developed a model of pollen tube tip growth with the intrinsic coupling of hydrodynamics, cell wall and ion dynamics by integrating all three into a complete system. The model can be used to analyze the role of turgor, osmotic pressure, cell wall extensibility, ion dynamics and hydrodynamics in the growth of pollen tubes.
