Photosynthesis and plant energy biology

The capture of CO2 by photosynthesis using sunlight is fundamental to the maintenance of life on earth.

About

The capture of CO2 by photosynthesis using sunlight is fundamental to the maintenance of life on earth. At the Research School of Biology, we study the energy metabolism of plants, algae and cyanobacteria, including the functioning of light capture, CO2 fixation and the interactions with respiration processes and how these determine growth and productivity of agricultural and natural ecosystems.

Our approaches range from synthetic biology to physiology and plant phenomics. The ANU node of the Australian Plant Phenomics Facility is developing new modeling and machine learning approaches to enables us to scale from leaf to field. This means we can translate our knowledge about the biochemistry and physiology of leaves and individual plants to their functioning in agroecosystems, in particular under changing climatic conditions.

Our research is embedded in the ARC Centre of Excellence for Translational Photosynthesis, the ARC Centre of Excellence in Plant Energy Biology, as well as the Bill and Melinda Gates-funded C4 Rice and RIPE (Realizing Increased Photosynthetic Efficiency) projects.

We have identified a carotenoid esterase and are looking to understand its function in plants and to manipulate it in 1-2 cereals species to enhance antioxidant and provitamin A levels.

Plant species that perform C3-C4 intermediate photosynthesis represent evolutionary steps between the most extended C3 plants and the highly efficient species that fix CO2 through the C4 pathway.

Open for Honours students

People

Genetic, biochemical and physiological tools are being used to explore which residues in Rubisco and its chiropractic helper protein, Rubisco activase, that influence their interactions.

This project explores how C4 plants, a group of stress-tolerant plants, respond to heat and drought. Knowledge learnt from this project will give insight into overcoming the current limits of photosynthesis and respiration in different plants and designing crops for improved food and energy production.

During the last decade the practice of laboratory-directed protein evolution has become firmly established as a versatile tool in biochemical research by enabling molecular evolution towards desirable phenotypes or detection of novel structure-function interactions (see Bershtein & Tawfik, 2008, Curr Opin Chem Biol 12:

Jeremy Pickett-Heaps

One of the illustrious founder members of RSBS passed away on 11 April 2021. Jeremy David Pickett-Heaps FAA, FRS worked in the (then) Department of Developmental Biology from 1968-70. His surveys of ultrastructural aspects of cell division in green algae (many collected from Lake Burley Griffin and Sullivan’s Creek) led him to a new formulation of the evolution of the Plant Kingdom, a landmark contribution in the plant sciences, now confirmed and fleshed out by sequencing data.
