有性生殖的成功对于所有高等生物的生存是必不可少的。显花植物作为地球上最繁荣、最多样化的陆生植物类群,其受精机制进化得极为复杂。为了适应陆地环境,植物进化出一种管状结构的花粉管,将静止的精细胞运送到胚珠内的卵和中央细胞中。花粉管由花粉的营养细胞(雄配子体)产生,其中有两个精细胞。花粉管在母体组织中的伸长和向胚珠的导航需要花粉管和雌性组织之间密切的细胞-细胞相互作用。单细胞花粉管是如何完成这一任务的,以及雌性组织是如何容纳花粉管的,这些问题吸引了许多植物生物学家。本文综述了近年来有关花粉管生长及其与雌性组织相互作用的分子机制的研究进展。我们还将讨论这一领域的未来前景。
Sexual reproductive success is essential for the survival of all higher organisms. As the most prosperous and diverse group of land plants on earth, flowering plants evolved highly sophisticated fertilization mechanisms. To adapt to the terrestrial environment, a tubular structure pollen tube has been evolved to deliver the immobile sperm cells to the egg and central cell enclosed within the ovule. The pollen tube is generated from the vegetative cell of the pollen (male gametophyte), where two sperm cells are hosted. Pollen tube elongation in the maternal tissue and navigation to the ovule require intimate cell–cell interactions between the tube and female tissues. Questions on how the single-celled pollen tube accomplishes such task and how the female tissues accommodate the tube have attracted many plant biologists. Here, we review recent progresses and concepts in understanding the molecular mechanisms governing pollen tube growth and its interactions with the female tissues. We will also discuss the future perspective in this field.
