Ornamental Plants: Molecular Biology and Biotechnology presents a comprehensive overview of the scientific principles that underlie the growth, breeding, and genetic enhancement of ornamental plant species. The book delves into molecular biology techniques and biotechnology applications used to develop aesthetically superior, disease-resistant, and environmentally adaptive plants. It explores plant physiology, genetic modification, tissue culture, and bioengineering strategies that drive innovation in the ornamental horticulture industry. This text bridges fundamental research with practical outcomes, including improved flower coloration, extended blooming periods, and tolerance to pests and climate stressors. The work also addresses the ethical and regulatory considerations involved in plant biotechnology. Ideal for students, researchers, and horticulturists, the book provides a solid grounding in both scientific theory and real-world application. Its multidisciplinary approach supports a deeper understanding of how cutting-edge biology is transforming ornamental plant cultivation and landscape design worldwide
