Multi-Omics Reveals Light-Quality-Dependent Phytohormone and Transcription Factor Networks Regulating Flavonoid Biosynthesis in Ludisia discolor

: We propose a novel regulatory model where light-induced ROS and phytohormone cascades activate specific transcription factors, enhancing structural gene expression in the flavonoid pathway. These findings elucidate the molecular mechanisms of light-driven secondary metabolism, providing valuable insights for the sustainable agriculture and ex situ conservation of endangered medicinal orchids.
