Figure 1.

Timeline for omics technology development and typical omics-based plant studies over the past two decades. The proposal of omics concepts is shown in yellow, key events related to the development of omics technologies are indicated in green boxes and typical omics-based plant studies were illustrated by blue. Abbreviations: NGS, next-generation sequencing; SMRT, single molecule real-time; MSI, mass spectrometry imaging; Smart-seq, switching mechanism at 5′ end of the RNA transcript sequencing; ATAC-seq, assay for transposase-accessible chromatin with high-throughput sequencing; CRISPR/Cas9, clustered regularly interspaced short palindromic repeats/CRISPR-associated9; ONT, Oxford Nanopore Technology.
