Genomic Designing for Biotic Stress Resistant Pulse Crops

Biotic stresses, such as insects, bacteria, fungi, and viruses, cause significant yield loss in crops. Understanding the interaction between crop plants and these stresses is crucial for developing resistant varieties. Advanced genetic and genomic techniques, such as molecular breeding, transgenics, genomic-assisted breeding, and genome editing, have been used to identify genes conferring resistance to biotic stresses in pulse crops. This volume discusses the types of biotic stress agents, genetic diversity, gene pools, classical genetics, genetic engineering, molecular mapping, genomics-aided techniques, and case studies on genome editing for developing resistant crop varieties.

Biotic stresses, such as those caused by insects, bacteria, fungi, viruses, and oomycetes, significantly impact crop yields, causing losses of 31-42% during the growing season and 6-20% during post-harvest stages. Understanding the intricate interactions between crop plants and these biotic stresses is crucial for developing resilient crop varieties. Advanced genetic and genomic approaches, including molecular breeding, transgenics, genomic-assisted breeding, and the recently emerged genome editing, are vital in addressing the security of FPNEE (food, health, nutrition, energy, and environment).

Whole genome sequencing and genotyping-by-sequencing have provided precise information about the genes conferring resistance to biotic stresses, enabling gene discovery, allele mining, and shuttle breeding. This has expanded the possibilities for designing crop genomes with built-in resistance to these stresses.

This comprehensive volume, consisting of nine chapters dedicated to different pulse crops, delves into various types of biotic stress agents and their effects on crop plants. It highlights the available genetic diversity among cultivars for biotic stress resistance, explores potential gene pools for interspecific gene transfer, and discusses classical genetics and traditional breeding methods for transferring stress resistance traits. Success stories of genetic engineering in developing biotic stress-resistant varieties are showcased, along with molecular mapping of genes and QTLs underlying stress resistance and their marker-assisted introgression into elite varieties. Emerging genomics-aided techniques, such as genomic selection, allele mining, gene discovery, and other cutting-edge approaches, are also discussed.

By understanding the complex interplay between biotic stresses and crop plants, we can develop innovative strategies to enhance crop resilience and ensure food security in a rapidly changing world.
