Extracellular adenosine-5'-triphosphate (ATP) induces a number of cellular responses in plants and animals. Some of the molecular components for purinergic signaling in animal cells appear to be lacking in plant cells, although some cellular responses are similar in both systems [e.g. increased levels of cytosolic free calcium, nitric oxide (NO), and reactive oxygen species (ROS)]. The purpose of this review is to compare and contrast purinergic signaling mechanisms in animal and plant cells. This comparison will aid our overall understanding of plant physiology and also provide details of the general fundamentals of extracellular ATP signaling in eukaryotes.
细胞外三磷酸腺苷(ATP)在动植物中引发了许多细胞反应。动物细胞中存在的一些用于嘌呤能信号转导的分子成分似乎在植物细胞中缺失,尽管这两个系统中的一些细胞反应是相似的[例如,细胞质游离钙、一氧化氮(NO)和活性氧(ROS)水平增加]。本综述的目的是比较和对比动物和植物细胞中的嘌呤能信号转导机制。这种比较将有助于我们全面了解植物生理学,并提供真核细胞细胞外 ATP 信号转导的一般基本原理的详细信息。
