Plants grow in dense stands receive light signals of varying strength from all directions. Plant responses to light signals from below should be considered in light‐mediated plant interactions, as their consequences for plant performance differ among ecological and agricultural settings. Where to perceive, how to integrate and what type of responses can be induced by light signals from below are major questions that need to be solved to expand our understanding of light‐mediated plant interactions.

颠倒植物相互作用：来自物质下方的光信号

生长在茂密林分中的植物从各个方向接收不同强度的光信号。在光介导的植物相互作用中应考虑植物对来自下方的光信号的反应，因为它们对植物性能的影响因生态和农业环境而异。在哪里感知，如何整合以及来自下方的光信号可以诱导什么类型的反应是需要解决的主要问题，以扩大我们对光介导的植物相互作用的理解。
