Molecular Advances in Insect Resistance of Field Crops

Abstract

In an era of intensive agriculture, insecticides play a predominant role in insect pest management, which comes at the cost of injuring the environment and human health. Therefore, efforts to manage the insect pest populations using the least amount of pesticides as possible are the chief goal of sustained production with increased productivity. Exploiting host plant resistance in crop plants to develop resistant cultivars to insect pests is a promising approach concerning public and environmental safety. Plants have several chemicals, which confer resistance to the attack by the insect pests. The level of tolerance and resistance varies with the phenotypes of the plants. Many omics technologies are being used to investigate, comprehend, and develop plant resistance. Among them, proteomics deals with the quantification, identification, and modification that alter the functions of proteins in an organism. Metabolomics entails the high-throughput characterization of metabolites and products of the biochemical pathway, while transcriptome analysis aids in the analysis of gene expression in an organism. These omics technologies assist us in identifying novel chemical compounds with the potential to be resistant to insect pests. A multi-omics approach is required to understand everything from genes to ecology. We give a quick overview of the topics in this chapter like current omics technologies and tools and methods of multi-omics, as well as approaches taken by various researchers to understand host plant resistance, its governing factors, and their utility in insect pest management.
