Mathematical modelling of the light input signalling pathways to the Arabidopsis circadian oscillators
Natural light is defined by multiple factors including photoperiod length, intensity, and wavelength, all of which regulate the dynamics of Arabidopsis circadian oscillators. Mechanistically, light regulation of the circadian oscillator occurs through multiple synergistic and/or independent …

Engineering a cyanobacteriochrome two-component system into a synthetic, light-controlled gene expression system for plants
… way. Our lab has reengineered the CcaS/R light receptor two-component system from cyanobacterium Synechocystis sp. PCC 6803 into a plant-compatible synthetic light-controlled gene expression system called Highlighter. This system was initially deployed in transiently transformed *Nicotiana …

Characterisation of mutants involved in Phytochrome A nuclear import and signal transduction
… caused shift of the action spectrum to the red light ( 657 nm) in addition to the normal action peak in the far-red light (730 nm). The mutated photoreceptor was stable and was not degraded in red light and continuous white light. The mutated photoreceptor was constitutively localised in the …

Immunogenetic Study of Autoimmunity-Associated Variants in Selected TNF Superfamily Genes
… datasets, which I used to prioritise genes and signalling pathways from GWAS summary data. This pointed to several Single Nucleotide Polymorphisms (SNPs) proximal to or intronic within genes involved in LIGHT (TNFSF14) signalling. To establish the settings in which these SNPs regulate gene …

Coordination of the Arabidopsis thaliana circadian clock
… in both constant environmental conditions and light-dark cycles. Closer examination revealed that spatial waves of clock gene expression propagate both within and between organs. A combination of modelling and experiment revealed that these spatial waves are the result of the period differences …

Exploring the Function of Cytochrome c6A
… background. Exposure to a harsh fluctuating light regime, named DISCO Light, in photomixotrophy was found to lead to a growth penalty in the absence of c6A. No other significant growth phenotypes could be observed in continuous light, continuous darkness, or milder fluctuating light regimes …

Subcellular localisation and functional analysis of UVR8, a UV-B specific signalling component in Arabidopsis
UV-B is an integral component of the daylight spectrum that regulates plant gene expression and development, but very little is known about how plants perceive UV-B. Although UV-B-induced damage and repair have been extensively investigated, the mechanisms by which UV-B is perceived as a signal, …
