Advances in Phenomics and its Application in Crop Research

Abstract

Phenomics refers to the systematic study at the genomic level of all the phenotypes of an organism or cell under a variety of different environmental conditions. With the continuous improvement of plant phenotype acquisition technology and equipment as well as the rapid development of genomics, proteomics, metabolomics, bioinformatics and big data computing technology, high-throughput phenomics analysis plays an increasingly important role in germplasm identification, genetic mapping, functional gene mining and other aspects. High-throughput phenomics research is becoming a key field to break through the future research and application of crop science, providing accurate and efficient decision support for crop breeding and cultivation management. Therefore, it is of great significance to fully exploit multi-omics information and accelerate high-throughput phenotypic studies to fully understand the relationship between crop genotypes, phenotypes and environment, to discover and reveal the regulatory genes and mechanisms of important agronomic traits and to promote the researches of crop functional genomes and crop genetic improvement. In this review, the phenotypic development of phenomics were summarized, the current phenomics research platform and imaging system and its application in crop root structure, canopy structure, biological and abiotic stress were systematically discussed, with a view to providing a reference for highthroughput acquisition and analysis of crop phenotypes and accelerating the application of phenomics in crop breeding.
