Biochemistry and Molecular Biology of Beneficial Plants presents the new concepts and insights in plant biochemistry and molecular biology. It describes the plant secondary metabolites to explore possibilities and approaches for the modification of plant metabolism and their potential antimicrobial activity. The issues discussed range from tool development to basic biochemical knowledge about how the secondary metabolites. It also discusses the potentially useful compounds from mustard leaves, velvet bean, marine plants and alga for therapeutic effects. Some chapter discusses neutraceutical milky mushroom, phytohormones, microbial interactions and role in defense responses.
