"Over recent decades, in the fields of plant biology and crop breeding, a huge amount of sequencing data and omics-related information involving genomics, transcriptomics, proteomics, interactome, and so on, have been produced and continue to increase dramatically. In the meantime, bioinformatics tools were developed and upgraded to be capable of analyzing the resulting big data, which can reveal new aspects of biological mechanisms and networks as well as acquire the genetic information of agronomic traits to aid in breeding programs of crops. Bioinformatics tools are powerful to solve biological problems by predicting novel functions of genes, protein-to-protein interactions, and biological networks. Nowadays, these tools are indispensable, and the knowledge of bioinformatics/systems biology is increasingly prosperous"--
