New and Future Developments in Microbial Biotechnology and Bioengineering: Crop Improvement through Microbial Biotechnology delves into the innovative techniques used to enhance plant growth and development. Edited by Ram Prasad PhD, this 1st edition book provides a comprehensive overview of microbial biotechnology’s role in sustainable agriculture, particularly focusing on gene transfer across different kingdoms to achieve desirable traits in crops. The text covers key mechanisms such as avirulence factors from bacteria and fungi, viral coat proteins, chitinase enzymes, virulence factors from nematodes and mycoplasma, insecticidal toxins from Bacillus thuringiensis, and herbicide tolerance enzymes from bacteria. It highlights the practical applications of these technologies in improving crop productivity under stress conditions, while also exploring the beneficial interactions between plants and microbes. Ideal for researchers, students, and professionals in biotechnology and agriculture, this book is essential reading for understanding how microbial biotechnology can drive advancements in crop improvement.
