Crop Improvement: Biotechnological Advances – Biomedical ScienceThe field of biotechnology is advancing at a fast pace. The availability of low-cost DNA/genome sequencing technologies has led to the discovery and functional characterization of myriad of genes imparting stress tolerance and quality traits. The ‘omics’ group of technologies including genomics, proteomics, transcriptomics and metabolomics has revolutionized the agricultural biotechnology sector. The Nobel Prize-winning technology, such as the genome editing technique, is being employed to edit various gene functions in plants aiding in crop improvement. This technology may be adopted very quickly by consumers compared with the transgenic technique because the genome-edited plants have no adverse effects on the genome of the plant itself and on the environment and related species/non-target organisms. In this book, authors have attempted to compile the latest techniques of agricultural biotechnology and their applications in crop improvement. Certain chapters have been dedicated to describe the use of nanotechnology, a fast emerging new technique in the agriculture sector.Features Development, potential and safety issues in biotechnology Advances in genomics, proteomics and transcriptomics in agriculture Protein bioinformatics and its applications Genetically modified (GM) technology and its implications Genome editing in crop improvement Marker-assisted selection (MAS) in crop improvement Mutation breeding Cryobiotechnology Nanotechnology and biosensorsThis book includes real-world examples and applications making it accessible to a broader interdisciplinary readership.

Macrophomina Phaseolina: Ecobiology, Pathology and Management provides insights into the sustainable prevention and treatment of this wide-spread challenge to plant health. With a focus on agricultural as well as non-food plant challenges, the book highlights diverse approaches and provides central insights. The pathogen?of M. phaseolina affects the fibrovascular system of roots and basal internodes of its host, impeding the transport of water and nutrients to the upper parts of the plant, thus resulting in progressive wilting, premature drying and dying, loss of vigor, and reduced yield.

Finally, the book explores the interaction of M. phaseolina with soil, microbes and ecological conditions to control disease-causing strategies. Recognizing the necessity that strategies applied to manage the disease should have no or minimum effect on ecological resources, the book focuses on alternative sustainable management technologies such as mix-cropping, the use of antagonistic bacteria and fungi and microbial biosurfactants, plant growth promoting antagonistic rhizobacteria and how cultural practices may also play an important role.
