Overview of strategies for exploration of metabolic pathways in nature producers. Pre-omics analysis methods consist of chemical analysis (e.g., isotope labeling, NMR analysis) and molecular techniques (e.g., gene deletion, gene expression, DNA sequencing by genome walking); omics technologies include genomics, transcriptomics, proteomics and metabolomics. Both of them offer powerful tools to discover new genes, gene clusters, transcription factors as well as pathways for synthesis of bioactive compounds
