Abstract

This thesis will be set out in five chapters. The first outlines the introduction and the rationale of the research. Chapters 2-4 describe and discuss the methods and results of the three component studies in detail. Chapter 2 is written in the style of a manuscript for New Phytologist, and Chapters 3 and 4 are written in the style of the Journal of Experimental Botany. The intent is for these chapters to be edited and submitted for publication at a later date. The final chapter summarizes and discusses the findings of the three studies as a whole, before concluding the thesis
