Phytochromes control almost every aspect of plant biology, including germination, growth, development, and flowering, in response to red and far-red light. These photoreceptors thus hold considerable promise for engineering crop plant responses to light. Recently, structural research has shed new light on how phytochromes work. Genomic and transcriptomic studies have improved our understanding of phytochrome loss, retention, and diversification during evolution. We are also beginning to understand phytochrome function in cyanobacteria and eukaryotic algae.
光敏色素控制着植物生物学的几乎每个方面，包括种子萌发、生长、发育和开花，以响应红光和远红光。因此，这些光感受器在设计作物对光的反应方面具有巨大的潜力。最近，结构研究为光敏色素的工作方式提供了新的线索。基因组和转录组研究增进了我们对光敏色素在进化过程中的丢失、保留和多样化的理解。我们也开始了解光敏色素在蓝细菌和真核藻类中的功能。
