Localized responses to changes in the red to far-red ratio (R:FR) allow plants to efficiently forage for light in patchy canopies, and to fine-tune physiological activities to the local light environment. Recent studies are elucidating the molecular mechanisms that mediate localized responses to R:FR and the functional implications of these responses.

植物色素的反应：放眼全球，就地采取行动

对红与远红比率（R：FR）的变化的局部响应使植物可以有效地觅食斑驳的冠层中的光，并根据当地的光环境微调生理活动。最近的研究正在阐明介导对R：FR的局部反应的分子机制以及这些反应的功能含义。
