Chlorophyll biosynthesis in higher plants
WebFeb 17, 2024 · Thirteen KEGG pathways were identified to be significantly enriched in the DEGs identified from the L3 vs. L1 comparison, including photosynthesis, carbon fixation in photosynthetic organisms, carotenoid biosynthesis, porphyrin and chlorophyll metabolism, and plant hormone signal transduction. WebMoreover, the stimulating effect of melatonin on Amaryllidaceae alkaloids biosynthesis was observed. In plants grown in the medium enriched with melatonin the galanthamine content was, on average, 58.6 times higher, and the lycorine content was 1.5 times higher as compared with the control.
