Plant root development and hormone signalling during drought stress
… In response to drought in plants, various hormones are vital regulators, because they are able to manipulate plant development and in some cases minimise the adverse impact of drought. Therefore, understanding how the plant root system will adapt to a soil drying challenge is crucial. Of …

The Integration of Metabolite and Hormone Signalling Drives Seedling Development
… plant biology, acting as structural components, signalling molecules, and sources of energy. As such, the availability of sugars has important implications for plant growth and development. Sugar levels rise and fall as part of a daily cycle, while cues from other environmental stimuli are also …

The impact of diabetes on cardiac remodelling after myocardial infarction: potential role of thyroid hormone signalling
… investigated possible implications of thyroid hormone (TH) signalling in either reducing or preventing this response. TH signalling has a regulatory role in metabolism, cardiac function, growth and ischaemic stress. Acute myocardial infarction (AMI) was induced in age–match healthy control rats …

Assessment of plant hormone quantification as a new physiological trait for crop breeding using a new classification method for crop performance under drought
… a key opportunity to test whether a stress hormone and/or hormone balance (ABA, ethylene and/or ABA/ethylene) could be used as a physiological trait for breeding for abiotic stress resilience. Due to the complexity of spatial and temporal variation of hormone accumulation (ABA and ethylene) …

Exploiting crosstalk between growth and immunity in plants : the role of the <i>Phytophthora infestans</i> effector AVR2 in potato late blight
… the BSLs, implicated in brassinosteroid pathway signalling – a major hormone signalling pathway in plants associated with growth and development. This work investigates the role of AVR2 and its host targets in pathogen virulence, with focus on the link between the brassinosteroid pathway and …

Identification of a mitogen-activated protein kinase, p56, which mediates the self-incompatibility response in Papaver rhoeas L.
… to identify and characterize components of the signalling network that mediate the SI response. Recent studies have revealed that p56, a mitogen-activated protein kinase (MAPK), is involved in activation of PCD during SI. MAPKs have been shown to be important signalling components in a range of …

Investigating the role of phytohormones during desiccation in two evolutionarily distinct resurrection plants
… loss. This thesis focused on profiling phytohormone abundances in two evolutionarily distinct resurrection plant species; Craterostigma pumilum and Xerophyta schlechteri, during a dehydration time course. The objective was to elucidate some of the molecular processes that occur in the context …

Evaluation of the toxicity of the brominated flame retardants, PBDE-47 and HBCD, in neuronal cell lines
… and lipid metabolism. Genes involved in thyroid hormone signalling, neurodegenerative diseases and nervous system development were also preferentially regulated. The fatty acid DHA altered the expression of genes that were also regulated by PBDE-47 or HBCD, and HBCD modulated DHA-induced gene …

Neurobiological and metabolic mechanisms of binge-eating in anorexia and bulimia nervosa
… the impact of acute, psychological stress on gut hormones, endocrine responses, and inhibitory control in women acutely ill with the binge-eating and purging subtype of anorexia nervosa, bulimia nervosa and matched controls. Chapters 3 through 5 report the results of this study. Chapter 3 focuses …

Characterisation of the Auxin Signalling Pathway in Vitis vinifera L. cv. Shiraz
… a finely tuned transcriptional system. The auxin signalling pathway consists of the transcription factors, auxin response factors (ARFs), the transcriptional repressors, auxin/indole-3-acetic acid (Aux/IAAs), and the transport inhibitor response 1/auxin signalling F-box (TIR1/AFB) proteins that …

Targeting the DNA damage response in hormone-driven cancers
… the DDR is explored as a therapeutic target in hormone-driven cancers. Hormone signalling has been shown to drive DNA repair, and is therefore a worthwhile model to study mechanisms of sensitisation to DNA damaging therapeutics. The androgen receptor (AR) has been linked to radio-resistance in …

An investigation into the role of deubiquitinating enzymes in plant disease resistance
… proteasome has been implicated in diverse signalling events including embryogenesis, hormone signalling and disease resistance. Ubiquitin moieties are ligated to target proteins through the sequential activities of E1, E2 and E3 enzymes leading either to proteasomal degradation or other …
