Genomic Designing for Biotic Stress Resistant Vegetable Crops

Biotic stresses, such as insects, bacteria, fungi, and viruses, cause significant yield loss in crops. Understanding these interactions is crucial for developing resistant varieties. Advanced genetic and genomic techniques, including molecular breeding, transgenics, genomics-assisted breeding, and genome editing, are essential for addressing FPNEE security. This book discusses these strategies and highlights the success stories of genetic engineering in developing biotic stress-resistant varieties. It also explores emerging genomics-aided techniques for creating resistant crops with improved quantity and quality.

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, genomics-assisted breeding, and the recently emerged genome editing techniques, are vital in addressing the security of food, health, nutrition, energy, and the environment (FPNEE).

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

The nine chapters in this volume, dedicated to individual vegetable crops or crop groups, delve into various types of biotic stress agents and their effects on crop plants. They explore the genetic diversity available in cultivated cultivars with respect to biotic stress resistance. The potential gene pools for interspecific gene transfer are identified, and the classical genetics of stress resistance and traditional breeding methods for transferring these traits to cultivated varieties are discussed. Success stories of genetic engineering in developing biotic stress-resistant varieties are highlighted. Molecular mapping of genes and QTLs underlying biotic stress resistance is explored, and marker-assisted introgression into elite varieties is discussed. Emerging genomics-aided techniques, such as next-generation sequencing and bioinformatics, are also discussed in detail.

By understanding the complex interactions between biotic stresses and crop plants, utilizing advanced genetic and genomic tools, and implementing innovative approaches, we can enhance crop resilience and contribute to sustainable agricultural practices. This volume serves as a valuable resource for researchers, breeders, and policymakers in the field of crop improvement, providing insights into developing resilient and sustainable crop varieties to address the challenges posed by biotic stresses.
