SummaryPhotoperiod is an environmental signal that varies predictably across the year. Therefore, the duration of sunlight available for photosynthesis and in turn the ability of plants to accumulate carbon resources also fluctuates across the year. To adapt to these variations in photoperiod, the metabolic daylength measurement (MDLM) system measures the photosynthetic period rather than the absolute photoperiod, translating it into seasonal gene expression changes linked to photoperiodic growth. In this Tansley Insight, we briefly summarize the current understanding of the MDLM system and highlight gaps in our knowledge. Given the system's critical role in seasonal growth, understanding the MDLM system is essential for enhancing plant adaptation to different photoperiods and optimizing agricultural production.

探索代谢日长测量系统：对光周期生长的影响


摘要Photoperiod 是一个环境信号，在一年中可以预测地变化。因此，可用于光合作用的阳光持续时间以及植物积累碳资源的能力在一年中也会波动。为了适应光周期的这些变化，代谢日长测量 （MDLM） 系统测量光合作用周期而不是绝对光周期，将其转化为与光周期生长相关的季节性基因表达变化。在这篇 Tansley Insight 中，我们简要总结了当前对 MDLM 系统的理解，并强调了我们知识中的差距。鉴于该系统在季节性生长中的关键作用，了解 MDLM 系统对于增强植物对不同光周期的适应和优化农业生产至关重要。
