[Comparation and utilization of crop-omics databases].

Omics plays an important role in life sciences, which studies all the components and their interrelations as a whole. The omics databases collected and sorted out the relevant information to support omics research. The crop-omics database, based on the major food crop information, especially on the sequencing information and data mining, is set up to improve the basic research level of crop sciences and production, which potentially benefit our grain stock. Here, we summarize crop genomics, transcriptomics, proteomics, metabolomics and phenomics, explore the development and utilization status of crop-omics, and reveal that the comprehensive utilization of multiple omics databases has become an important research method for crop sciences in the era of high throughput information.
