Noxious and invasive weed species are a major problem faced globally, both in developed and developing countries. These weeds have a major impact on the agricultural sector, as they compete for nutrients and space, and can contaminate commercially important crops. The most common means of combating weeds has been in the application of herbicides, such as RoundUp (Glyphosate). However, unregulated use, coupled with a lack of research and development into novel herbicide modes of action has led to the development of several resistant weed species. My research aims to develop a novel herbicide my targetting the Diaminopimelate pathway in plants, which is responsible for the biosynthesis of the amino acid, lysine.
