Abstract

We examined the proteomic profiles of three registered opium poppy cultivars (Papaver somniferum L.) having different alkaloid contents. The study was conducted on both the stem and capsule organs. A high number of differentially expressed proteins (DEPs) were identified between the cultivars and the organs. We analyzed DEPs for their contribution in GO terms and KEGG pathways. The up-regulated DEPs were significantly enriched in photosynthesis and translation, for morphine-rich and noscapine-rich cultivars, respectively. The data depicted that photosynthesis is crucial for Benzylisoquinoline alkaloid (BIA) biosynthesis, but different processes are also effective on morphine and noscapine biosynthesis, which occur at different branches in the biosynthetic pathway. The protomic profiles revealed that energy demand is more effective in morphine biosynthesis, while translational control has a leading role in noscapine biosynthesis. This is the first report demonstrating the organ-based and cultivar-based protein expression differences in mature poppy plant.
