Environmental regulation of plant nutrition: Linking secondary metabolites to cellular communication and epigenetic memory formation

The Hawkesbury Institute for the Environment (HIE) at the University of Western Sydney (UWS) is dedicated to excellence in research. The mission of the HIE is to generate insights into the impacts of a rapidly changing environment on Australia's agricultural, natural and managed ecosystems. Our academic staff build on existing national and international reputations in plant molecular (epi)genetics, physiology and terrestrial plant ecology.

ABOUT THE PROJECT
Carotenoids are colourful pigments found in plants that are essential for human health. In plants, carotenoids are required for photosynthesis, photoprotection and the production of signaling molecules (e.g. hormones and volatiles) that promote chloroplast to nucleus communication, shoot branching, microorganism (e.g. mycorrhizal) symbiosis and tolerance to drought stress (Cazzonelli and Pogson, Trends in Plant Science 2010; 15: 266-274). We have shown that perturbations in the biosynthesis of carotenoid-derived signaling molecules can affect plant development processes (Cazzonelli et al., Plant Cell 2009; Van Norman, et al., PNAS 2014; Avendaño-Vázquez et al., Plant Cell, 2014).

We identified a carotenoid mutant with altered root architecture and hypothesized mycorrhizal symbiosis. A forward genetics approach identified revertant plants that restored wild type root development and we are elucidating the molecular (genetic) and physiological (hormones) mechanisms controlling root development.
The long-term goal is to understand how carotenoids synthesized in the chloroplast signal epigenetic regulatory processes in the nucleus to facilitate stress signaling and developmental acclimation. This project can offer experience in phenotyping metabolic mutants, mutant screening, genetic mapping and the quantification of chloroplast and nuclear gene expression.

The aims are to: 1) investigate how a carotenoid enzyme and altered carotenoid accumulation can influence root development, and 2) establish links between prolonged changes in temperatures, branching and carotenoid-derived signaling metabolites. Students will have the opportunity to design and implement their own molecular experiments


The goal of the EElab (https://www.facebook.com/Environmental-Epigenetics-Laboratory-315894808574055/ ) are to understand how environmental signals such as temperature, light and wind alter metabolic signaling processes and induce structure changes to DNA or RNA thereby promoting cellular memory formation, stress acclimation and transgenerational adaptation. The PhD candidate is anticipated to commence in 2017.
