Genome Scale Pathway-Pathway Co-functional Synergistic Network (PcFSN) in Oryza Sativa

Abstract

Cohesive network modelling and systems biology have emerged as extremely potent tools which helps understanding the combinatorial effects of biomolecules. Synergistic modulation among biomolecules (e.g., enzymes, transcription factors, microRNAs, drugs, etc.) are significant in finding out complex regulatory mechanisms in biological networks and pathways. In some cases, although combinatorial interactions among some biomolecules in specific biological networks is available, our knowledge in that particular domain is very limited with context to a genomic scale. Here we explore the pathway-pathway network to identify and understand the network architecture of metabolic pathway mediated regulations at genomic and co-functional levels, in rice. Using network transformation methods, a genome scale pathway-pathway co-functional synergistic network (PcFSN) was constructed. Finally, the PcFSN modules are extracted. This in turn helps to identify the miRNAs and genes associated with the pathways, especially linked to the central metabolic network in rice.
