植物受精作用开始于雌雄性细胞的融合,虽然目前可以通过细胞学的操作,用化学或电激等方法实现雌雄配子的体外融合,形成合子.但植物在自然界的受精过程中,雌雄配子间的融合是随机的还是有所选择的,即精卵细胞之间是否存在识别尚无定论.动物受精作用的研究表明精卵细胞的融合包括许多复杂的过程.存在于哺乳动物小鼠卵膜透明带上的ZP3蛋白是其识别蛋白,卵细胞表面亦有精卵特异吸附的功能蛋白.而在植物中这些问题都没有结论.
Fertilization of plants begins with the fusion of male and female cells, although the integration of male and female gametes can be achieved in vitro by chemical or electrostimulation methods through cytology, but zygotes are formed in plants during fertilization in nature. However, Fusion is random or selected, that is, whether the identification of sperm cells there is no conclusion.Animal fertilization studies have shown that the fusion of spermocytes, including many complex processes.On the mammalian mouse zona pellucida ZP3 protein is a functional protein that recognizes proteins and also has sperm-egg-specific adsorption on the surface of egg cells, and none of these problems have been concluded in plants.
