| Summary: | Given the interest in medicinal plants that have potential pain-relieving effects without the side
effects of NSAIDS and opioids, secondary metabolite pathways in plants are being studied
extensively. However, there are several valuable compounds for which the biosynthetic
pathways are yet to be understood. Hence, the study aimed to investigate the relevant secondary
metabolite pathways in three species of medicinal plants which are known to have analgesic
properties - P. granatum, A. paniculata, T. divaricata. In P. granatum the pathways studied were
flavenoid biosynthesis pathways and Anthocyanin biosynthesis pathways. For both these
pathways, key enzymes were identified after annotation using E2P2 and PathoLogic on
PathwayTools. Pathways in A. paniculata were studied similarly, but were focused on the
synthesis of andrographolide. The pathways that lead to the synthesis of an andrographolide
precursor were identified to have high frequency scores and the enzymes involved were
identified as well. Finally, RNA samples of T.divaricata from a dwarf and wild-type plant were
extracted and transcriptomes from two organs of the dwarf plant were assembled towards the
pathway analysis. |
