Bamboo is one of the most important nontimber forestry products in the world. Light is not only the most critical source of energy for plant photosynthesis but also involved in regulating the biological processes of plants. However, there are few reports on how blue/red light affects Moso bamboo. This study investigated the growth status and physiological responses of Moso bamboo () to blue/red light treatments. The growth status of the bamboo plants was evaluated, revealing that both blue- and red-light treatments promoted plant height and overall growth. Gas exchange parameters, chlorophyll fluorescence, and enzyme activity were measured to assess the photosystem response of Moso bamboo to light treatments. Additionally, the blue light treatment led to a higher chlorophyll content and enzyme activities compared to the red light treatment. A tandem mass tag quantitative proteomics approach identified significant changes in protein abundance under different light conditions with specific response proteins associated with distinct pathways, such as photosynthesis and starch metabolism. Overall, this study provides valuable insights into the physiological and proteomic responses of Moso bamboo to blue/red light treatments, highlighting their potential impact on growth and development.
竹子是世界上最重要的非木材林产品之一。光是植物光合作用最关键的能量来源，也参与调控植物的生物过程。然而，关于蓝/红光如何影响毛竹的报道却很少。本研究调查了蓝/红光处理对毛竹生长状况和生理响应的影响。评估了竹子植株的生长状况，结果表明，蓝光和红光处理均促进了植株高度和整体生长。测量了气体交换参数、叶绿素荧光和酶活性，以评估毛竹的光系统对光处理的响应。此外，与红光处理相比，蓝光处理导致更高的叶绿素含量和酶活性。串联质量标签定量蛋白质组学方法鉴定了不同光照条件下蛋白质丰度的显著变化，与光合作用和淀粉代谢等不同途径相关的特异反应蛋白。总的来说，本研究为毛竹对蓝/红光处理的生理和蛋白质组学响应提供了有价值的见解，强调了它们对生长和发育的潜在影响。
