This exciting new textbook presents current knowledge of plant biology, highlighting important topics for future development and research. Starting with the evolutionary history of plants, the book addresses the dynamic nature and regulation of plant genomes, the conversion of products of photosynthesis into the vast diversity of molecules that comprise the plant body, and the nature and coordination of growth, development, and reproduction of the plant. The book next describes how these fundamental properties of plants are impacted by their surroundings: by the physical environment including light, daylength and temperature, and by interactions with other organisms - pests and pathogens, pollinators and microbes that supply nutrients. Finally, the book outlines the history, importance and future of human interactions with plants. Key features: Each chapter is prefaced with Learning Objectives directly related to the text that follows as a convenient scene-setter for both students and instructors Throughout the book, text descriptions are accompanied by informative, high-quality illustrations aiding understanding of complex concepts and mechanisms Extensive online material expands and enhances understanding of many of the topics covered, allowing students to test their knowledge of chapter content and prepare for formal examinations Carefully designed for, and written at, a level accessible to all undergraduate biologists who have a grounding in the fundamentals of molecular biology and biochemistry, Essential Plant Biology is also a valuable resource for postgraduates in plant research. For lecturers, the breadth of coverage and clear organization facilitate the teaching of both complete courses in plant science and more focused topics in plant biology.
