Ginkgo biloba L. Responds to Red and Blue Light: Via Phenylpropanoid and Flavonoid Biosynthesis Pathway

Light quality is a key environmental factor affecting plant growth and development. In this study, RNA-seq technology was used to explore the molecular mechanisms of ginkgo metabolism under different monochromatic lights. Leaves were for transcriptome sequencing analysis after being irradiated by red, blue, white LED After treatment, 2040 differentially expressed genes (DEGs) identified. Gene Ontology (GO) showed that DEGs annotated into 49 terms. Kyoto Encyclopedia Genes Genomes (KEGG) enrichment 736 enriched in 100 metabolic pathways, 13 pathways significantly enriched, especially ‘phenylpropanoid biosynthesis’ ‘flavonoid biosynthesis’. Further expression two Ginkgo biloba adapts blue light mainly promoting GbFLS synthesize quercetin, kaempferol, myncetin, red GbDFR leucocyanidin. Nine randomly selected qRT-PCR verification, gene results consistent with sequencing. conclusion, study first mechanism response lights, it will lay foundation research application cultivation leaf-use G. biloba.
