Technical Abstract: Research in the life sciences in the post-genomics age is currently undergoing a dramatic transformation. Genome-scale methods are revolutionizing the study of plant-pest interactions and are revealing a complex process (including direct resistance genes and regulatory networks) involved in plant defense responses. The key components of genomics and functional genomics include map-based QTL linkage analysis, genome sequencing and gene annotation, gene expression profiling, gene modification and regulation of expression, which can be readily applied to improve our understanding of host and pest resistance, virulent factors of pests, genetic mechanisms of host defense, and regulatory aspects of expression of host resistance. By taking the advances of the integrated approach, our sorghum research program at USDA-ARS Plant Science Research Laboratory, Stillwater, Oklahoma, is currently focused of discovering of novel genes, analysis of their expression patterns in response to pest attack, and determination of their roles in host defense. The work is leading to the detailed characterization of many genes that confer resistance as well as the technologies for the precise manipulation and deployment of these resistance genes for effective and sustained controls of pests in cereal crops.
