Pollen Tube Growth

Pollen Tube Growth

The pollen tube is an elongated tubular cell, a typical polar growth cell, whose growth is restricted to the apical region, resulting in a heterogeneous distribution of its cell wall components along the longitudinal axis of the pollen tube. In angiosperms, pollen tubes transport sperm cells to oocytes through apical growth to complete double fertilization. Pollen tubes have been used as model plant cells to study the biogenesis and molecular mechanisms of cell signaling, protein polarity transport, cell polarity generation and maintenance, and cytoskeletal space structure. Through biophysical techniques, researchers analyze the structure and function of pollen tubes, which in turn provides a theoretical basis for the study of plant fertilization and growth and development.

CD BioSciences is committed to establishing a professional and comprehensive biophysical technology platform for plant pollen tube growth research, aiming to reveal the structure, apical growth, and mechanical force mechanisms of pollen tubes, which have important biological functions and significance for plant fertilization and fertility, as well as crop yield.

Structural Analysis of Pollen Tubes

Field emission scanning electron microscopy (FESEM) and atomic force microscopy (AFM) provide non-destructive observation and technical support for the study of pollen tube cell walls. With the advantages of in-situ, non-destructive, and high-resolution, AFM allows direct observation of the fine structure of pollen tubes in situ in the closest physiological condition and easy measurement of physical parameters of the surface structure.

Mechanical Force Test

Plants are regulated by mechanical stimuli at all stages of growth and development. Since the structure and mechanical properties of the tissues of each part of the pistil are different, the pollen tube must monitor and differentiate the pattern, level, and duration of various types of mechanical stimuli. By responding quickly and appropriately, integrity is maintained during passage through the pistil. Biophysical techniques can be utilized to measure the stiffness and elasticity of pollen tubes, thus exploring their mechanical force properties and adaptations during growth.

Tip Growth Observation

Polar tip growth of pollen tubes is a complex kinetic process with important biological functions and significance for plant fertilization and fertility as well as crop yield. The process of pollen tube growth includes many aspects, the most important of which are the dynamics of the pollen tube cytoskeleton and cytoplasmic movement. The dynamics of pollen tube cell division, elongation, and cell wall changes can be visualized through high-magnification microscopy, thus revealing the specific process of apical growth.
