<p>Light is essential in regulating plant growth and development across their life cycle as a crucial factor in photosynthesis and energy production. Plants adjust their morphological traits in response to light intensity and quality changes. However, the impact of light quality on pigment levels, oxidative stress, reactive oxygen species (ROS) generation, antioxidant defense mechanisms, and biomass production continues to be a subject of ongoing investigation. Specialized photoreceptors allow plants to perceive light signals across various wavelengths, activating downstream signaling pathways that modify gene expression and affect physiological and developmental processes. This review explores the recent potential of dynamic lighting strategies in regulating plant growth and development, specifically seedling development. Furthermore, it highlights the importance of the circadian system in aligning internal biological rhythms with external light cycles, which is essential for regulating seasonal growth and dormancy in plants. Further, an effort has been made to understand the molecular mechanisms of light-regulated gene transcription, the role of plant hormones in light signal transduction, and their effects on plant physiology, summarizing prior research and assessing the significant influence of light quality on plants.</p>
