Optical tools to unlock phenotypic plasticity

Aim The primary aim of this research is to investigate the potential of ultra violet radiation as a catalyst for unlocking phenotypic plasticity in Chlorella vulgaris, a common freshwater green algae. Furthermore, the project aims to explore the underlying mechanisms of these changes, hypothesized to be driven by epigenetic modifications as stress responses. The duration of these induced changes will be observed for future research considerations. This study seeks to advance our understanding of phenotypic plasticity in microalgae and the role low intensity UV stress in this process, with implications for evolutionary biology, ecology, and algal biotechnology.

Transient gene silencing in corals and coral larvae

Aim (1) The primary objective of this project is to investigate the potential of transient gene silencing, specifically utilizing antisense oligonucleotides (oligos), in mature corals and coral larvae. This aim is particularly focused on the AyRhp1 gene found in the Acropora yongei coral species.

Aim (2) To assess the possibility of using transient gene silencing as a tool for future coral research and conservation efforts: If successful, this project could set the stage for broader use of gene silencing in coral research. It might also open up new avenues for coral conservation, such as genetically modifying corals to be more resilient to climate change.

100 Diatom phenomes

Aim: To make a large interspecies comparison of diatom phenomes. The project is carried out in colaboration with the 100 Diatom Genomes consortia and will apply high-throughput phenotyping technology to 100 newly sequenced diatomes. Phenotyping is done using a combination of fluorometry, flow cytometry, spectroscopy and robotics. 

Colaborators: Professor Tomas Mock; Lilian Hoch (PhD student); Professor Peter Ralph

Sister project: 100 diatom genomes 

temperature response kinetics of coral larvae

Aim: Determine the photo-termal charscteristics of planula holobiont shortly after coral spawning. The project will leverage the use the Phenoplate 2.0 system to determine the temperature response kinetics of planulae from Hawaii barier reef spaning. 

Colaborators: Dr. Jen Matthews; Dr. Ariana Huffmyer

Location: Hawaiʻi Institute of Marine Biology

Phenotyping of corals from the Great barier reef

Aim: Phenotype corals living in mangrove ecosystems to evaluate their thermal resiliance compared to corals from the inner reef of the Great Barrier Reef (GBR). The project is part of a larger effort to characterise coral systems that could be translocated to the wider GBR to suport increased resiliance of the reef ecosystem in response to climate change. 

Colaborators: Dr. Emma Camp; Hadley Englan (PhD student); Christine Roper (PhD student); Dr. David J. Suggett;

Location: Pord Douglas - Low Isles

phosphate sensor

Aim: To demonstrate that the level of biologically active phosphate in microalgae can be determined using non-invasive fluorometry. The project builds uppon previous research where the technique has been demonstrated to be effective in higher land plants.   

Colaborators: Dr. Jan Červený; Professor Peter Ralph
