Plant Development Over Multiple Timescales.
PhD thesis, University of York.
Abstract
Fundamental research on plant development is critical to understand plant responses to environmental stimuli and disease. Regulatory networks integrate this information over a daily timescale and a seasonal timescale, in part through the circadian clock. The clock demonstrates downstream control of important transitions, including the transition to flowering and the concurrent initiation of senescence. In this thesis, I first analyse how the clock maintains control of daily processes and interacts with changing energy availability across age. The initiation of senescence is a process that occurs rapidly alongside the production of a bolt. I introduce an extension to a technique, single-plant-omics, to understand the changing transcriptome during this rapid transition. This technique has the added advantage of finding genes whose expression can predict physiological outputs. In addition to the benefits of fundamental research, I demonstrate how the single-plant-omics technique can be applied to a crop plant, barley. This study reveals the variable responses of barley to a fungal pathogen. Altogether, these studies present new methods to understand plant development over multiple timescales.
