Sexual reproduction relies on the successful fusion of the sperm and egg cell. Despite the vast differences between plants and animals, there are similarities at a molecular level between plant and animal reproduction. While the molecular basis of fertilization has been extensively studied in plants, the process of capacitation has received little attention until recently. Recent research has started to uncover the molecular basis of plant capacitation. Furthermore, recent studies suggest that the key molecules in plants and animal fertilization are functionally conserved. Here, we review new insights for our understanding of capacitation of pollen tube and fertilization in plants and also propose that there are commonalities in the process of sexual reproduction between plants and animals.

有性生殖依赖于精子和卵细胞的成功融合。尽管动植物之间存在巨大差异，但动植物繁殖之间在分子水平上仍存在相似之处。虽然在植物中广泛研究了受精的分子基础，但是直到最近，获能的过程才受到关注。最近的研究已经开始揭示植物获能的分子基础。此外，最近的研究表明，植物和动物受精中的关键分子在功能上是保守的。在这里，我们回顾了新的见解，以了解植物对花粉管的吸收能力和受精能力，并提出在动植物之间有性生殖的过程中存在一些共性。
