Like phytohormones, peptide hormones participate in many cellular processes, participate in intercellular communications, and are involved in signal transmission. The system of intercellular communications based on peptide-receptor interactions plays a critical role in the development and functioning of plants. One of the most important molecules are reactive oxygen species (ROS). ROS participate in signaling processes and intercellular communications, including the development of the root system. ROS are recognized as active regulators of cell division and differentiation, which depend on the oxidation-reduction balance. The stem cell niche and the size of the root meristem are maintained by the intercellular interactions and signaling networks of peptide hormone and ROS. Therefore, peptides and ROS can interact with each other both directly and indirectly and function as regulators of cellular processes. Peptides and ROS regulate cell division and stem cell differentiation through a negative feedback mechanism. In this review, we focused on the molecular mechanisms regulating the development of the main root, lateral roots, and nodules, in which peptides and ROS participate.
与植物激素一样，肽激素参与许多细胞过程，参与细胞间通讯，并参与信号传递。基于肽 - 受体相互作用的细胞间通讯系统在植物的发育和功能中起着关键作用。其中最重要的分子之一是活性氧（ROS）。ROS参与信号传导过程和细胞间通讯，包括根系的发育。ROS被认为是细胞分裂和分化的活性调节因子，这取决于氧化还原平衡。干细胞微环境和根分生组织的大小由肽激素和ROS的细胞间相互作用和信号网络维持。因此，肽和ROS可以直接和间接相互作用，并作为细胞过程的调节因子发挥作用。肽和ROS通过负反馈机制调节细胞分裂和干细胞分化。在本综述中，我们重点关注了肽和ROS参与的主根、侧根和根瘤发育的分子机制。
