花粉管生长的基本特征是胞外离子流的极化、胞内离子梯度和振荡动力学。这些功能在花粉管生长的调节范围广泛的时空组织功能，如胞吐和胞吞，肌动蛋白细胞骨架重组，细胞壁沉积和组装，细胞内信号，受精和自交不亲和。最近，通过建立一个房室模型，我们已经证明，在花粉管联合收割机的尖端和柄结合在一个集成和自我调节系统的离子和生长动力学。在建模和丰富的实验数据的最新发展可以用来开发一个系统模型，提供了一个综合的观点，影响花粉管生长的不同功能之间的相互作用。
Essential features of pollen tube growth are polarization of extracellular ion fluxes, intracellular ion gradients, and oscillating dynamics. These features in pollen tube growth are regulated by a wide range of spatiotemporally organized functions such as exocytosis and endocytosis, actin cytoskeleton reorganization, cell wall deposition and assembly, intracellular signalling, fertilization, and self-incompatibility. Recently, by developing a compartmental model, we have demonstrated that the tip and shank in a pollen tube combine in an integrative and self-regulatory system of ion and growth dynamics. Recent developments in modelling and the wealth of experimental data can be used to develop a systems model that provides an integrative view of the the interactions between the different functions that affect pollen tube growth.
