This module is about the application of modern biology to problems in agriculture and plant science. It aims to provide an understanding of the environmental and biological limitations on agricultural productivity and to give an appreciation of the potential impact of transgenic technology in overcoming the restrictions of classical breeding methods. The module will explore the current understanding of plant genome structure, gene cloning technologies and the techniques used in plant transformation. Applications of plant genetic engineering to disease, pest and herbicide resistance; to water use and abiotic stress tolerance, to manipulating metabolism and development will be considered.
