Lateral root (LR) branches from primary root. LR is vital for plants acquiring water and nutrients from soil, especially under stress conditions. LR development involves the complicated signaling network, which has not yet been fully understood. Melatonin, a novel endogenous plant regulator, plays a role in the regulation of LR development. However, we still have limited knowledge about melatonin-modulated signaling during LR development. Our recent study identifies that reactive oxygen species (ROS) acts as downstream signaling of melatonin to facilitate LR development. The recently identified receptor of melatonin in plants controls a signaling module involving G protein, ROS, and Ca. Based on these findings, we propose a novel signaling network for LR development controlled by melatonin.
侧根（LR）从主根分支。LR 对植物从土壤中获取水和养分至关重要，尤其是在胁迫条件下。LR 的发育涉及复杂的信号网络，目前尚未完全理解。褪黑素作为一种新型内源性植物调节剂，在调节 LR 发育中发挥作用。然而，我们对褪黑素调节 LR 发育过程中的信号转导仍然知之甚少。我们最近的研究表明，活性氧（ROS）作为褪黑素的下游信号转导分子，促进 LR 的发育。最近在植物中鉴定出的褪黑素受体控制着一个信号模块，该模块涉及 G 蛋白、ROS 和 Ca。基于这些发现，我们提出了一个由褪黑素控制的新的 LR 发育信号网络。
