Research Associate in Photosymbiosis and Animal Behaviour

The role

We are seeking a highly motivated Postdoctoral Researcher to join Vengamanaidu Modepalli’s group to conduct research on the HFSP-funded project “Plant-like solar tracking in a photosymbiotic animal”. The project is for 3 years, and it is in collaboration with the Assoc. Prof. Katherina Petrou from the University of Technology Sydney, Australia. The successful candidate will work with the photosymbiotic sea anemone to uncover how endosymbiotic algae communicate with and influence host nervous systems. You will join a collaborative research environment with access to state-of-the-art molecular, aquarium, imaging, and omics facilities.

Project description:

Among marine invertebrates, many have formed mutualistic symbioses with photosynthetic partners, such as algae. In this relationship, the animal provides protection and nutrients, and in exchange, the algae provide energy through photosynthesis. This partnership is highly prevalent in corals and sea anemones, underpinning the productivity and biodiversity of coral reef ecosystems. Researchers have observed that marine animals living in symbiosis with photosynthetic algae, such as sea anemones, move in response to light (https://doi.org/10.1242/jeb.250242).

While the survival of both organisms relies on a mutually beneficial partnership, little is known about their communication or the signal driving these intriguing light-driven behaviours. Our proposed research will explore the mechanisms that connect algal photosynthesis with animal behaviour. We will do this by investigating the host nervous system and the physiology and metabolism of the photosynthetic algae. We will conduct experiments to explain how photosynthetic partners influence the behaviour of their hosts in order to gain a new understanding of this fascinating process, providing new insights into the fundamentals of the photosymbiotic relationship in animals.
